Upoko 4: Ngā Hikohiko Mana Taumata-MW me te Whai Huatanga o te Tahuritanga

4.1 Te Huringa o te Silicon Carbide (SiC)

I te tauine 1.2MW, ko ia ōrau o te whai huatanga ka rite ki te 12kW o te wera ekāoreme whakawātea. Ko ngā IGBT tuku iho e hangai ana ki te Silicon (Insulated Gate Bipolar Transistors) kua kaha ake te mana o te umanga, engari he uaua ki a rātou te karo i ngā mate whakawhiti i ngā auau teitei. Ko ngā MOSFET Silicon Carbide (SiC) te paerewa hou mō te utu MW nā te mea:

4.3 Rere Mana Ahu-rua (V2G/V2H)

Ehara i te mea he kaihoko noa iho te teihana 1.2MW; he rawa whatunga pea. Mā te hiko hiko rua-ara, ka taea e te kahui taraka hiko te mahi hei tipu hiko mariko nui. I ngā wā e nui ana te tono whatunga, ka taea e te DEMS te tohu ki ngā rihi hiko kia tangohia te kaha mai i ngā pākahiko o ngā taraka ki te whatunga (Waka-ki-Whatunga). Me whai rauropi whakahaere matatau tēnei kia mōhio ai kei te nui tonu te utu o ngā taraka mō ā rātou wehenga kua whakaritea, engari ka hangaia he awa moni hou mō ngā kaiwhakahaere kahui.

4.4 Ngā Whakawhiti Ngāwari me ngā Whakawhiti Āhuatanga

Hei whakatairanga ake i ngā rohe o te whai huatanga, he maha ngā pūnaha 1.2MW e whakamahi ana i ngā momo āhua resonant (pēnei i te LLC, i te DAB rānei – Dual Active Bridge). Mā ēnei tikanga ka taea te Whakawhiti Ngaohiko Kore (ZVS) te Whakawhiti Auaha Kore rānei (ZCS), ā, ka tata kore te mana i ngaro i te wā e whakawhiti ana i waenga i ngā āhua ON me OFF o ngā transistors. He mea nui tēnei hei pupuri i te whai huatanga o te teihana o >97% mai i te tāuru AC ki te putanga DC.

Upoko 5: Ngā Pūnaha Whakamatao Wai: Te Whakahaere Wera i te Tauine

5.1 Te Ahupūngao o te Wera i roto i te Utu Megawatt

Ko te ngaronga o te pūngao i roto i te āhua o te wera te hoariri nui rawa atu o te utu hiko teitei. Mena he 95% te whai huatanga o te utu hiko 1.2MW, ka puta he 60kW o te wera. Hei tauira, he nui te wera hei whakamahana i ētahi whare nunui i te takurua. E toru ngā wāhi e arotahi ana tēnei wera:

2. Te Taura Utu me te Hononga.
3. Te Pūhiko me ngā Pae Pahi o roto o te Waka.

5.2 Ngā Taura Whakamatao-Wai: Te Whiti i te Ārai Taumaha

Hei kawe i te 1,200A mā te whakamahi i te parahi hau-whakamatao tuku iho, he matotoru, he taumaha hoki te taura, kāore e taea e te tangata te hapai. Ka whakamahia e ngā taura wai-whakamatao he whakamatao motuhake (he ranunga wai-glycol, he wai dielectric rānei) e rere ana i roto i ngā awa e karapoti ana i ngā kawe parahi. Mā tēnei ka taea te hanga i tētahi wāhanga parahi iti ake, kia ngāwari ai, kia māmā ai hoki te taura, me te pupuri tonu i te pāmahana mahi haumaru (i raro iho i te 60°C te nuinga).

• Ngā Pito Whakamua Kaha (AFE):Ka whakamahia e ngā pūnaha 1.2MW ngā AFE hei whakarite kia tino rite te iahiko e tangohia ana mai i te whatunga hiko ki te sinusoidal, ā, kia rite hoki te āhua ki te ngaohiko (Power Factor ≈ 1.0).
• Te Whakapōturitanga Harmoni Katoa (THD):E whakahau ana ngā paerewa ture (pērā i te IEEE 519) kia noho tonu te THD i raro i te 5%. Hei whakatutuki i tēnei i ngā tauine MW, me tātari matatau me te whakahaere PWM auau-tiketike (Pulse Width Modulation).

6.4 Te Otinga: Ngā Pūnaha Rokiroki Pūngao Pūhiko (BESS)

Hei whakaiti i te pānga ki te whatunga hiko, kāore i te maha te hono tika o tētahi teihana 1.2MW ki te whatunga hiko i te wā kotahi. Engari, ka honoa ki tētahi BESS.

Mā te whakaurunga o te kawenga 1.2MW ki roto i te whatunga tohatoha ka tino whakarerekē te āhua o te hiko. E ai ki te pihi PV (hononga Mana-Ngaohiko), i te pikinga ake o te mana hohe (P), ka heke te hiko (V) i te pūwāhi hononga noa (PCC). Mēnā ka nui ake te kawenga i te "pūwāhi ihu" o te pihi, ka pāngia te pūnaha e te hinganga hiko. Mō ngā teihana 1.2MW, ka whakahaerehia e ngā miihini ngā rangahau rere kawenga hei whakarite kia noho tonu te whatunga i roto i te rohe pumau. He maha ngā wā ka hiahiatia he tāutanga o ngā Static Var Compensators (SVC) me ngā STATCOM (Static Synchronous Compensators) hei tautoko i te mana tauhohe, e "tautoko" ana i te hiko i te wā e utu ana i te au teitei.

• Te Whakaiti i te Āhuatanga:He nui ake te whai hua o ngā tātari LCL i ngā tātari L noa i ngā auau teitei ake, engari ka taea e rātou te whakararu i te haruru. Ka whakamahia e ngā pūnaha 1.2MW ngā rauropi "Active Damping" i roto i te pūmanawa whakahaere hei pehi hiko i ēnei haruru me te kore e tāpiri i ngā ātete nunui, koretake hoki.

Ko te "Kimimi" e pā ana ki ngā piki me ngā heke o te kaha o te mārama e puta mai ana i ngā huringa ngaohiko. Ina piki ake, ina heke iho rānei te utu hiko 1.2MW, ka taea e ia te whakaputa i ngā RVC e neke atu ana i ngā rohe kua whakatakotoria e ngā paerewa pēnei i te IEC 61000-3-7. Hei whakaiti i te kimimi, ka whakatinanahia e te DEMS he kawa "Tīmata-Ngāwari" me te "Mutu-Ngāwari". Engari i te peke tonu mai i te 0 ki te 1.2MW, ka whakanuia te mana mō te wā 5-10 hēkona. Mā tēnei ka taea e ngā kaiwhakahaere ngaohiko aunoa (AVR) o te whatunga me te BESS o te teihana te whakatikatika haere i te huringa.

6.8 Te Kaiwhakahaere Ipurangi Iti me te Āhua Mariko

I roto i tētahi pāka whakahaere rauemi hiko e mau ana i ngā taputapu hiko pūngao rā, BESS, me ngā taputapu utu hiko 1.2MW, ka mahi te papa katoa hei whatunga iti. Ka whakahaerehia e te kaiwhakahaere whatunga iti te "Anga Tohutoro Tukutahi" (SRF) hei pupuri i te pumau.

• Te Āhuatanga Mariko:Ka taea te whakarite i ngā kaitahuri hiko 1.2MW hou kia rite ki ngā miihini hurihuri tuku iho. Mā te werohanga, te mimiti rānei i te iti o te hiko hei whakautu ki ngā huringa auau, ka whakaratohia e rātou te "Inertia Mariko," e āwhina ana ki te whakau i te whatunga rohe katoa i te mea ka whakakorehia atu ngā tipu waro me te hau.

Me aroturuki e te DEMS te whakamahinga katoa o te papa kawe waka—tae atu ki ngā rama whare putunga, ngā pūnaha aunoa, me ngā waeine pouaka whakamātao. Mēnā ka tata te kawenga katoa ki te rohe o te whare, ka "whakakore" te DEMS i te kawenga mai i ngā utu EV i te tuatahi, ka whakaitihia te mana mō te wā poto kia pahemo rā anō te tihi. Ka oti pai tēnei me te kore e pakaru ngā pakaru.

7.4 Te Matapae me te Ako Mīhini

Ka whakamahia e ngā tūāpapa DEMS matatau te AI hei matapae i te tono utu i runga i ngā raraunga o mua, te huarere (e pā ana ki te whānuitanga o te EV), me ngā whakahōutanga waka i te wā tūturu. Mā te matapae ka tae mai ētahi taraka Akomanga 8 e rima i waenga i te 2:00 PM me te 2:30 PM, ka taea e te DEMS te utu wawe i te BESS me te whakamatao i mua i ngā pūnaha whakamatao o te teihana.

7.5 Haumarutanga Ipurangi i roto i te Whakahaere Pūngao

Nā te mea e hono ana te DEMS ki te whatunga hiko (mā OpenADR, mā ngā tikanga rite rānei) me ngā raraunga whakahaere o te waka, he tino whainga nui tēnei mō ngā whakaekenga ipurangi. He mea nui te whakamunatanga pakari, ngā kōwae haumarutanga taputapu (HSM), me te manatoko API tino pakari. Ka taea te whakamahi i tētahi DEMS kua pakaru hei whakararuraru i te whatunga hiko ā-rohe, hei whakararuraru rānei i ngā mahi whakahaere a te kamupene.

Upoko 8: Ngā Āhuatanga ā-Tinana me ngā Rauemi o ngā Hononga Taumata-MW (MCS)

8.1 Te Paerewa Pūnaha Utu Megawatt (MCS)

Mō ngā tau maha, i whakawhirinaki te umanga ki te CCS (Combined Charging System), engari ko te pāmahana o te CCS he 500A anake. Kia eke ki te 1.2MW, i whānau mai he paerewa hou: ko te MCS. He mea hanga motuhake te MCS mō ngā whakaritenga ergonomic me te hangarau o ngā waka taumaha.

8.2 Whirihoranga Pine me te Ātete Whakapā

He nui ngā pine mana o te hononga MCS ka taea te whakahaere i te hiko tae atu ki te 1250V me te 3000A i ngā whakamahinga o muri mai.

• Tikanga Maukati:I te mea he nui te iahiko, me raka pūmau te hononga ki te waka i mua i te tīmatanga o te rere o te hiko. Ka whakamahia e te MCS he pine raka aunoa pakari e taea ai te tu atu i te ahotea ā-pūkaha o tētahi taura taumaha.

8.4 Te Pūmau me te Huringa Ora

He uaua te ora o ngā hononga arumoni. Ka tukua ki runga i te raima, ka tukuna ki te tote rori, ā, ka whakamahia kia maha ngā wā i te rā. Ka whakamatautauria ngā hononga MCS mō ngā huringa taumau neke atu i te 10,000. Kei roto hoki i ēnei he pūoko pāmahana kua whakauruhia ki roto i te kakau me te taha o ngā pine, e whakarato ana i ngā raraunga wā-tūturu ki te rihi hei whakawhāiti i te hiko mēnā ka tīmata te hononga ki te wera rawa.

8.5 Te Whatunga Ātete Wera o te MCS

Hei whakahaere i te 1.2MW, ka whakatauirahia e ngā kaihangarau te hononga mā te whakamahi i tētahi whatunga ātete wera (R-th).

• Ātete Whakapā (R-whakapā):Ka whakaitihia mā roto i ngā hononga puna pēhanga teitei me ngā mata honohono hiriwa-ki-hiriwa.
• Ātete Arataki (R-cond):Me rere te wera mai i ngā pine ki te koropiko whakamatao. Ka whakanuia tēnei mā te whakamahi i ngā matū kohua e kawe ana i te wera engari e ārai ana i te hiko i roto i te kakau hononga.
• Ātete Whakawhitiwhiti (R-conv):Ko te pai o te mimiti wera e te wai e rere ana. Mā te whakanui ake i te aueue o te rere o te wai whakamatao (te tau Reynolds teitei ake) ka pai ake te R-conv engari me nui ake te mana papu.

Mā te whakataurite i ēnei ātete e toru, ka taea e te MCS te pupuri i te pāmahana pā o te kakau i raro i te 50°C ahakoa he iti noa te henimita e rere ana te 1.2MW.

8.6 Te Hototahitanga Hikohiko (EMC) i roto i ngā Hoahoa MCS

Ka taea e ngā iahiko DC nui e whakawhiti ana i ngā auau teitei (mai i ngā kaitahuri o te teihana) te whakaputa i te haruru hikohiko nui. Me mahi te taura me te hononga MCS hei pūnaha ārai hei ārai i te pokanoa ki ngā pahi whakawhitiwhiti tairongo o te taraka (pēnei i te CAN, i te Automotive Ethernet rānei). Kei roto i tēnei:

• Parenga 360-Ngā Tohu:Mā te whare whakarewa o te mono MCS ka whakaratohia he whare herehere Faraday tonu.
• Ngā Pīra Ferrite:He maha ngā wā ka whakauruhia ki te huihuinga taura hei pehi i te haruru aratau-noa auau-tiketike.

Upoko 9: Hanganga Pūmanawa: Ngā Kawa, te Haumarutanga Ipurangi, me ngā Whakawhitiwhiti Kōrero

9.1 ISO 15118-20: Te Pūtake o te Utu MW

He tino uaua ake te whakawhitiwhiti kōrero i waenga i te rihi hiko 1.2MW me te taraka arumoni i te rūrū ringa noa o te rihi hiko kāinga. Kua whakapūmau te umanga i te ISO 15118-20 (te putanga "Dash 20"), e whakauru ana i ētahi āhuatanga nui mō te wā megawatt:

• Mono & Utu:Mā tēnei ka taea e te taraka te whakamana me te whakamana aunoa i te utu ina monohia, mā te whakamahi i ngā tiwhikete matihiko kua rongoatia i roto i te waka. Mō tētahi rōpū waka, ka kore e hiahiatia he kāri RFID, he taupānga rānei, ka tere ake te wā hurihanga.
• Mana Whakahaere Hihiri:Mā tēnei ka taea e te waka me te rihi hiko te whiriwhiri anō i ngā taumata hiko i ia hēkona ruarua. He mea nui tēnei mō te utu hiko 1.2MW, ka tere te huri o te kaha o te pākahiko ki te tango hiko i a ia e whakakī ana, e wera ana hoki.
• Tautoko ā-rua:E whakamārama mārama ana i ngā tikanga mō te whakawhiti pūngao V2G (Waka-ki-te-Whatunga).

9.2 OCPP 2.0.1: Te Whakahaere i te Hanganga

Ahakoa e whakahaerehia ana e te ISO 15118 te kōrero i waenga i te motuka me te taputapu utu, ka whakahaerehia e te Open Charge Point Protocol (OCPP) 2.0.1 te kōrero i waenga i te taputapu utu me te kapua. Mō tētahi wāhi 1.2MW, he mea nui te OCPP 2.0.1 nā te mea:

• Whakahaere Pūrere:E whakarato ana i ngā raraunga matatini mō te hauora o te pūnaha whakamatao wai, te pāmahana o ngā pine MCS, me te tūnga o ia waeine hiko.
• Utu Atamai:Mā tēnei ka taea e te DEMS pokapū te tuku i ngā kōtaha utu uaua ki te teihana, kia mau tonu ai te pāka i roto i ōna rohe whatunga.
• Haumarutanga Tauwhitinga:Ka whakarei ake i te haumarutanga o ngā raraunga utu, he mea nui mō ngā nama arumoni nui.

9.3 Te Whakaurunga Waea Pūkoro

Kāore te teihana 1.2MW e mahi noa i te koretake. Me whakauru atu ki te pūnaha whakawhitiwhiti kōrero a te kahui (hei tauira, Geotab, Trimble).

• Matapae SoC:I te whakatata atu o te taraka ki te papa whakahaere waka, ka tukuna e te pūnaha waea te Āhua o te Mana Whakahaere o nāianei me te wā taenga mai e matapaetia ana ki te DEMS. Kātahi ka taea e te teihana te "whakamahana" te "whakamatao" rānei i te hanganga hei whakarite.
• Te Arotautanga o te Ara:Mena ka mōhio te DEMS ko te wāhanga e whai ake nei o te haerenga a te taraka he 100km noa iho, ka whakatau pea rātou ki te utu i te taraka ki te 50% anake i te 1.2MW, ka penapena i te hauora o te pākahiko me te whakaiti i te kawenga i runga i te whatunga hiko.

9.4 Te Haumarutanga Ipurangi i roto i te Pūnaha Rauropi MW

Nā te kaha nui o tētahi teihana 1.2MW ka waiho hei ūnga mō te "Whakamataku Pūngao." Ka taea e te kaiwhakaeke e whiwhi ana i te mana whakahaere o tētahi rōpū o ēnei teihana te pātītī me te whakaweto i a rātou hei hanga i ngā wiri auau i roto i te whatunga hiko ā-motu.

• Ngā Kōwae Haumarutanga Pūmārō (HSM):Whakamahia ana i roto i ngā rihi hei penapena haumaru i ngā kī whakamuna.
• Whakamunatanga Mutunga-ki-Mutu:Me whakamuna ngā raraunga katoa i waenga i te taraka, te rihi, me te kapua mā te whakamahi i te TLS 1.3.
• Hanganga Kore Whakawhirinaki:Me wehewehe te whatunga i te pāka whakahaere rauemi hiko kia kore ai e taea te uru atu ki te hanganga utu mēnā ka pakaru te hononga Wi-Fi o te tari.

9.5 Te Aromatawai PKI mō te Mono me te Utu

Ko te whakatinanatanga o te ISO 15118-20 Plug & Charge me whai hanganga kī tūmatanui (PKI) matatau.

• Pūtake V2G CA:He mana whakahaere taumata-runga pono e tuku tiwhikete ana ki ngā OEM waka me ngā Kaiwhakahaere Teihana Utu (CSO).
• Ngā Tiwhikete Kirimana:Ina rongoatia ki roto i te taraka, ka whakaatu ēnei he kirimana whai mana tā te rangatira o te waka me tētahi kaiwhakarato ratonga nekenekehanga (hei tauira, Shell Recharge, ChargePoint rānei).
• Te Whakarato OEM:Ka whakawhiwhia te taraka ki tētahi tuakiri ahurei i te wā e hangaia ana, kia taea ai e te rihi te manatoko i tōna pono i mua i te whakawhiti i tētahi wati kotahi o te pūngao. Nā tēnei i ārai i ngā taraka "kore whakamanatanga" ki te whakamahi i tētahi pokapū kawe hiko tūmataiti 1.2MW.

9.6 OCPP 2.0.1 Te Whakatauira Raraunga me te Whakahaere Pūrere

He mea whakahau te neke mai i te OCPP 1.6 ki te 2.0.1 mō ngā pūnaha 1.2MW nā te mea kua whānui ake te tauira raraunga.

• Tauira Pūrere:I roto i te 2.0.1, ko ia wāhanga (pā hau, papu, kōwae SiC, whakapā) ka kiia he "Taurangi" ka taea te aroturuki me te whirihora. Mā tēnei ka taea e te pokapū mahi matua te mahi i te "Tiaki Matapae." Hei tauira, ki te piki haere te kukume o te iahiko o te papu whakamatao i roto i te wā, ka taea e te pūnaha te tohu kia whakakapia.i mua ika rahua, ā, ka motu te hiko o te teihana 1.2MW.
• Ngā Waehere Hapa Ritenga:He nui ake ngā waehere hapa whakamārama a te OCPP 2.0.1, e wehewehe ana i waenga i te hekenga o te ngaohiko taha-pūnaha, te wera rawa o te kakau hononga, te hapa BMS taha-waka rānei. Mā tēnei ka whakaitihia te "Wā Tohatoha ki te Whakatika" (MTTR), he mea nui mō ngā mahi kawe waka e nui ana te tūponotanga.

Upoko 10: Te Whakatauira Ōhanga me te Tātari TCO mō ngā Pāka Whakahaere

10.1 Te Āhua Pūtea o te Hanganga MW

He haumitanga nui te hanga i tētahi teihana 1.2MW. Ka taea te utu mō tētahi teihana kotahi, tae atu ki te hononga whatunga, ngā hikohiko, me te tohatoha MCS, i waenga i te $300,000 me te $600,000. Ina tāpirihia he BESS 2MWh me te 500kW o te pūngao rā, ka taea e te tapeke o te utu kaupapa mō tētahi pokapū kawe hiko iti te neke atu i te $2.5 miriona. Heoi, ka rerekē te tatau ina tirohia mā te tirohanga o te Utu Katoa o te Mana Whakahaere (TCO).

10.2 Wehenga o te CAPEX

Mō tētahi tāutanga 1.2MW 4-koki noa i tētahi pāka whakahaere ratonga:

1. Hononga Whatunga me ngā Whakawhiti:20-30% o te utu. Kei roto i tēnei ko ngā utu ratonga mō te kawe mai i te hiko ngaohiko-waenga ki te papaanga.
2. Ngā Taputapu Utu (PCS me ngā Pūwhakaputa):40-50% o te utu. He utu nui ngā kāpata modular SiC kounga teitei me ngā mīhini tohatoha MCS whakamatao-wai.
3. Ngā Mahi ā-Iwi me te Tāutanga:15-25% o te utu. Te keri i ngā taura nunui, te riringi i ngā papa raima, me te tāuta i te whakahaere taura o runga.
4. Ngā Utu Ngāwari:5-10% (Te whakaaetanga, te hangarau, me te whakatūnga).

10.3 OPEX me te Raru "Utu Tono"

He rerekē rawa te whakahaere i tētahi teihana 1.2MW i te whakahaere i tētahi DCFC paerewa.

• Ngā Utu Tono:Ko te nuinga o ngā ratonga whakahaere e utu ana i ngā kaihoko arumoni i runga i tā rātoutihite whakamahinga hiko i ia marama. Mā te pikinga kotahi o te 1.2MW ka hua ake he utu tono $15,000-$30,000 mō taua marama anake. Koia te take ehara a BESS me DEMS i te mea hangarau noa iho—he mea nui hoki mō te whakahaere i te OPEX.
• Te Tiaki:Me tirotiro auau ngā pūnaha whakamatao wai me te mahi i ngā papu. Nā te nui o te whakamahinga, me whakakapi pea ngā hononga MCS i ia 12-24 marama.

10.4 Tātaitanga ROI: Tīhiera me te Hiko 1.2MW

Me whakarite tātou i tētahi kahui taraka tīhiera Akomanga 8 e 10 ki ngā taraka hiko e 10 e whakamahi ana i tētahi pokapū 1.2MW.

• Ngā Penapena Wahie:Ko te hiko he iti ake i te 40-70% te iti ake i te maero i te tīhiera, ina koa mēnā ka whakamahia e te pāka kawe waka te rā me te utu atamai hei karo i ngā utu pīrahi.
• Ngā Penapena Tiaki:He iti ake ngā wāhanga e neke ana o ngā taraka hiko, ā, ka whakaitihia ngā utu tiaki mā te ~30%.
• Te Whai Hua o te Whakahaere:Mā te 1.2MW te kaha e utu ana, ka taea e ngā taraka hiko te pupuri i ngā huarahi me ngā wātaka rite tonu ki ngā taraka tīhiera. Mēnā me whakamahi rātou i ngā utu puhoi 150kW, e 12-14 ngā taraka e hiahiatia ana e te rōpū hei mahi i taua mahi, ā, ka nui ake te pikinga o te CAPEX.
• Wā Whakahoki:I roto i te maha o ngā mākete, me ngā whakatenatena o nāianei, ko te wā whakahoki mō ngā hanganga me te utu nui o ngā taraka kei waenganui i te 3.5 me te 5 tau. I te mea he maha ngā wā ka noho ngā taraka arumoni ki te mahi mō te 8-10 tau, he tino pai te ROI mō te wā roa.

10.5 Tātaritanga Tairongo: Te Pānga o ngā Taurangi

He maha ngā āhuatanga e pā ana ki te tauira ōhanga:

• Te utu o te tīhiera:Mā te pikinga $1 o te hinu tīhi mō ia karani ka taea te whakapoto i te ROI mā te tau kotahi.
• Te Ora o te Pūhiko:Mena ka tere ake te pakaru o te pākahiko i te mea e tumanakohia ana mā te utu 1.2MW, ka pāngia te TCO. Heoi, kei te whakaatu ngā pākahiko LFP (Lithium Iron Phosphate) me ngā pākahiko nikara-nui i te kaha ake o te ātete ki ngā reiti C-teitei i tērā i whakaarohia i mua.
• Ngā Tautoko a te Kāwanatanga:Ka taea e ngā whiwhinga tāke (pērā i te IRA i te US) te kapi i te 30% o te utu hanganga, ā, ka tino rerekē te pāngarau.

Upoko 10b: Te Whakatauira Ōhanga Tauanga mō ngā Rōpū Whakahaere

10.6 Te Utu Whakatauranga o te Utu (LCOC)

Hei whakataurite pono i te hiko me te tīhiera, me tatau tātou i te LCOC. Koinei te utu katoa mō ia kWh ka tukuna ki te waka i te roanga o te oranga o te taputapu (10-15 tau te nuinga). Ko te tātai mō te LCOC ko:LCOC = (CAPEX Tuatahi + Tapeke (OPEX Ā-Tau) + Tapeke (Utu Hiko)) / Pūngao Katoa i Tukuna (kWh)Mō tētahi pāka kawe waka 1.2MW, ko te utu LCOC noa kei waenga i te $0.15 ki te $0.25 mō ia kWh. He rerekē, ko te utu pūngao ōrite mō te tīhiera (kua whakatikatikaina mō te whai huatanga o te miihini) he $0.35 ki te $0.50 mō ia kWh. Ko te delta te tohu o te kaha penapena nui mō ngā kaiwhakahaere o ngā waka.

10.7 Ngā Pānga o ngā Hanganga Tari Whakamahinga

Me whakatere ngā pāka whakahaere waka i ngā utu ratonga matatini.

• Ngā Reiti Wā-Whakamahinga (TOU):E rima ngā wā ka nui ake te utu o te hiko i te 4:00 i te ahiahi i tō te 4:00 i te ata. Mā te utu hiko 1.2MW i te wā hē ka pakaru pea ngā penapena mō te wiki.
• Ngā Kaupapa Whakautu Hiahia (DR):Mā te tuku i te kamupene hiko ki te whakaiti i te mana utu o te teihana 1.2MW i ngā wā ohorere o te whatunga hiko, ka taea e te kaiwhakahaere te whiwhi moni whakahoki nui, i ētahi wā ka utua te utu tiaki ā-tau katoa o te teihana.

10.8 Te Huringa Ora o te Pūhiko me ngā Utu Whakakapinga

He hoari mata rua te utu hiko-teitei i te 1.2MW (tata ki te 2C ki te 3C mō te pākahiko arumoni 400-600kWh): ka whakahokia ngā waka ki te mahi i roto i ngā meneti, engari ka tere ake te koroheketanga o ngā pūtau mēnā kāore te whakahaere wera me ngā ānau utu o te pākahiko i hangaia hei mimiti i te ahotea.

I ngā tere 2C-3C, ka tere ake te whakakikorua o ngā pūtau lithium-ion me te pakaru o te hikohiko mēnā kāore e tika te whakaiti i te iahiko utu. E toru ngā tikanga e āraihia ai tēnei e ngā pākahiko taumaha hou: te whakamatao wai kaha e pupuri ana i te pāmahana pūtau i roto i te awhi piri ahakoa te kaha teitei, ngā anode kua tāpirihia ki te silicon e manawanui ana ki ngā iahiko utu teitei ake, me ngā ānau utu BMS matatau e whakaiti ana i te mana i te pikinga o te SoC - te "taper" e mōhiotia ana e tiaki ana i te 20% whakamutunga o te kaha.

Mō te kaiwhakahaere o te waka, ko te pātai whaihua ko te roa o te pākahiko. Ka taea e te kete e whakahaeretia pai ana me te nuinga o te utu i te 1C ki te 2C te pupuri i te 80% o te kaha i muri i te 3,000-5,000 huringa; mā te utu tonu i te 3C+ ka taea te whakaiti i tēnā ki te 1,500-2,500 huringa. I ngā utu pākahiko arumoni o nāianei o te $90-120/kWh, ko te utu mō te whakakapi i tētahi kete 500kWh he $45,000-60,000 - he mea tino nui tēnei i roto i tētahi take pakihi 1.2MW.

Ko ngā rautaki whakaitiiti:

• Te utu whai wāhitanga:Whakamahia te hiko 1.2MW mēnā e tika ana; me whakamahi i te 150-350kW te utu i te pō mō te nuinga o te whakawhiti hiko.
• Te whakatikatika wera:Ka whakamahanatia, ka whakamataotia rānei e te BMS te putea i mua i te wā megawatt kua whakaritea, nō reira ka tīmata te utu me ngā pūtau i roto i te matapihi pai 25-35°C.
• Pūhiko-hei-Ratonga (BaaS):He maha ngā kaiwhakahaere e rīhi ana i ngā pākahiko, e whakawhiti ana i te uara toenga me te mōrearea whakakapinga ki te kaiwhakarato, e huri ana hoki i te nama CAPEX hei raina OPEX e taea te matapae.

Ka kati te porowhita i te tiaki matapae.Ka aroturuki tonu ngā whare putunga hou i te hauora o te kete: ka aroturukihia te tipu ātete-roto, ngā rerekētanga o te pihi utu, me te whanonga wera mō ia waka, ka tukuna ki te pūnaha whakahaere waka. Ina kī mai ngā raraunga o te kete he tere te koroheketanga, ka neke aunoa te kaiwhakarite i taua waka ki ngā kōtaha utu ngāwari ake, ka tohu kia tirohia — ka whakaroa i te roa o te kete mā te 20-30% me te kore he huringa o te taumata ratonga. Mā tēnei huarahi e ahu mai ana i ngā raraunga ka huri te huringa ora o te pākahiko mai i te whakaaro tauākī hei taputapu whakahaere, ā, koinei tonu te momo mātauranga e wehewehe ana i tētahi whare putunga 1.2MW e whakahaere pai ana mai i tētahi e tahuna puku ana i ngā tahua whakakapinga.

10.9 Te Take Pakihi Rōpū Whakakotahi

Ina whakatauirahia ngātahitia te LCOC, te whakahaere taripa, me te huringa ora o te pākahiko, ka puta he tauira mārama: ehara te pūnaha 1.2MW i te mea he utu hiko nui ake noa iho — engari ko te pokapū o te pūnaha hiko. I te honoa ki te BESS e whakaiti ana i te pikinga o te tono me te pūngao rā e whakakore ana i ngā hokonga whatunga awatea, ka noho te utu hiko megawatt hei punga mō te pokapū hiko o te whare putunga hiko, ko te utu hiko katoa he iti iho i te utu tīhiera me te utu hiko 150kW noa.

Ngā Whakaaro Matua

• He nui te rerekētanga o te LCOC mō tētahi whare putunga hiko 1.2MW (ko te tikanga he $0.15-0.25/kWh) ki te $0.35-0.50/kWh e rite ana ki te tīhiera.
• Ka whakawhiwhia ngā kaiwhakahaere e whakarite ana i ngā wā megawatt me te mohio ki ngā utu a ngā TOU me ngā kaupapa urupare-tono.
• Ko te roa o te pākahiko te taurangi huna: me hono te utu 2-3C me te whakamatao wai me ngā ānau whakarara hei tiaki i te roa o te wā e mau ana te putea.
• Ka hurihia e te arai BESS te nama utu-tono hei awa moni whiwhi ratonga whatunga.

Whakapā mai Kei te hangaia e MIDA Power te heke mai o te utu megawatt i ēnei rā — mai i ngā utu tere DC kaha-teitei ki ngā pūnaha putunga hiko whakauru-BESS i hangaia mō te 1.2MW me tua atu. Mō te tauira LCOC taipitopito, te tautoko hoahoa papa, te utu whakatau tata rānei, whakapā mai ki tā mātou tīma. Ka āwhina mātou i a koe ki te hanga i ngā tau i mua i te hanganga o te papa.
