Kutarisira simba kwakangwara kunoshandisa sisitimu yekutonga simba panzvimbo (EMS) kuti igare ichisarudza nguva yekuchaja bhatiri, magovero esimba pakati pemachaja, uye nguva yekuburitsa simba kuti bhatiri rive rakareba, kufambisa mutoro, kana mhinduro yekudiwa. Nzira nhatu dzine simba guru dzinoyerwa inyaya ye peak-shaving dispatch, dynamic charger power caping kuburikidza neOCPP 2.0.1, uye kuronga mitengo kunoshandisa tariff spreads. Kana zvikashandiswa pamwe chete, zvinoderedza mutengo wesimba renzvimbo ne20–40%, zvinodzivirira machaja kubva kumiganhu yegrid, uye zvinogadzira mari itsva kubva kumapurogiramu emagetsi. Chinyorwa ichi chinotsanangura EMS hierarchy, nzira huru, uye maprotocol anoita kuti otomatiki ive yakavimbika pahub scale.

Zvinhu Zvinokosha Zvaunofanira Kuziva

• EMS ndiyo pfungwa yekudzora inobatanidza mabhatiri, machaja, PV, uye grid tariffs mudambudziko rimwe chete rekugadzirisa.
• Kugera ndebvu zvakanyanya ndiyo nzira inonyanya kukosha: kuvharira nguva yekuda kwemunhu mumaminitsi gumi nemashanu kunoderedza mutengo mukuru wezvinhu.
• Kutarisira mutoro unorema (DLM) kunoita kuti grid rekubatanidza risingakoshi rishande kune machaja makuru.
• Kuronga nguva zvichienderana nemitengo uye mhinduro yekudiwa kwezvinhu zvinoshandura nzvimbo yekuchengetera zvinhu kuita pfuma, kwete kungoshandisa nzira yekudzivirira mari chete.
• OCPP 2.0.1, ISO 15118, uye IEC 61851 kushanda pamwe chete ndizvo zvinhu zvisingachinjiki pakudzora otomatiki.

Chii Chinoita Kuti Nzvimbo Yekuchaja Ive "Yakangwara" Nhasi

Makore gumi apfuura, nzvimbo yekuchaja yeEV yaive muunganidzwa wemachaja akabatana nemita. Chaja yega yega yaitaurirana simba nemotokari yega, nzvimbo yacho yaitora chero nguva yayaitora, uye mushandi aigadzirisa kukuvara kwacho pakupera kwemwedzi. BESS hub yakangwara yakasiyana nemaumbirwo ayo: kufamba kwesimba rega rega kunoyerwa, sarudzo yega yega inogadziriswa, uye nzvimbo yacho inoita sechinhu chimwe chete chinogona kudzorwa.

Zvinhu zvinoumba hub yakangwara ndeizvi:

1. Kuyera panguva chaiyomutoro wenzvimbo, mamiriro ebhatiri ekuchaja (SoC), simba rekuchaja, uye—pazvinenge zvichibvira—kugadzirwa kwePV. 2.Kufanotaurakudiwa kwemotokari, simba remagetsi rinobuda nezuva, uye mahwindo emitero. 3.Kugadzirisaiyo inogadzirisa mari yakaderera kana mari yepamusoro mukati mezvirambidzo zvemuviri uye zvechibvumirano. 4.Kuurayiwaiyo inotumira zviratidzo zvekudzora kumachaja, PCS yebhatiri, uye nzvimbo yekubatanidza grid. 5.Kutevedzera mitemonezvibvumirano zvekubatanidza grid, mitemo yekuyera, uye zvinodiwa zvekuchengetedzwa kwemakombiyuta.

Hub isina hunyanzvi uhu ingori purazi hombe yekuchaja. Nadzo, inova chinhu chesimba chine mushandi anogona kuvimbisa kambani iyi kuti ichapa dhiraivha yakatwasuka uye oiendesa.

Hutungamiriri hweEMS: Mutongi weSaiti, Network yeChaja, Grid Edge

Kutarisira simba kwakangwara kunoshanda pazvikamu zvitatu zvakakomberedzwa, uye mashandisirwo akanakisa anoita kuti zvese zvitatu zvirambe zvakabatana:

Chikamu 1 — Mutongi wenzvimbo (EMS).EMS ndiyo inoita sarudzo. Inoshandisa data remitero, parameter yehutano hwebhatiri, mamiriro echaja, uye zvinongedzo zvekufungidzira, yobva yaburitsa hurongwa hwekutumira: nzvimbo dzekuchaja/kuburitsa bhatiri, miganhu yesimba rechaja, uye zvinangwa zvekutumira grid. Mapuratifomu eEMS ekutengeserana anovandudza hurongwa uhwu maminetsi ese 1-15, zvichienderana nekusagadzikana kwemusika.

Danho rechipiri — Network yekuchaja.Macharger anoita chirongwa ichi kuburikidza neOCPP. MuOCPP 2.0.1, EMS inogona kuisa miganhu yesimba rinoshanduka pane yega yega nguva yekuchaja, ichidzora nguva yega yega kuti nzvimbo irambe iri mukati memuganhu wayo. Iyi ndiyo nzira inoshandura kubatana kwe500 kVA kuita hub inokwanisa 960 kW: macharger anoshanda nesimba rakazara kana bhatiri rabuda, uye anodzikira kana risingabude.

Chikamu 3 — Mupendero wegrid.Nzvimbo yekubatanidza inoshuma data remita uye, muzvirongwa zve smart-grid, inogamuchira zviratidzo zvekunze—zviitiko zvekupindura zvinodiwa, maokisheni emagetsi, kana kutenderera kwemitengo panguva yekushandisa. EMS inoona izvi sezvipingamupinyi kana kuti zvinopinda mumitengo mukugadzirisa kwayo.

Nzira yekukundikana yekudzivirira ndeyekudzora bhatiri zvisina kuvharwa: kana bhatiri richitungamirirwa nemutengesi mumwe, machaja nemumwe, uye PV nechikamu chechitatu, hapana optimizer imwe chete iripo. Ndosaka mapuratifomu akabatanidzwa e [BESS charging station](https://www.midapower.com/bess-charging-station/)—apo EMS inotumirwa nebhatiri nemachaja—anogara achipa mhedzisiro iri nani pane mastacks emhando yepamusoro akabatanidzwa pamwe chete panzvimbo yacho.

Kutarisira Mutoro: Kuveura Nekugera Uye Kuchinja Mutoro

Nzira mbiri dzinoshanda dzeBESS hub energy management ndedzekugera nekuchinjisa mutoro. Dzinowanzo vhiringika, asi dzinonangana nezvikamu zvakasiyana zvemitero.

Kuveura ndebvu zvakanyanyaInovhara kudiwa kwegridi yepamusoro yenzvimbo kwemaminitsi gumi nemashanu. EMS inotarisa hwindo rekudiwa kwemagetsi; kana peak yakarongwa yasvika pamucheto, inoburitsa bhatiri nesimba rinodiwa. Kubatsira kwacho kudzivirira kubhadhariswa kwemagetsi - kazhinji mutengo mukuru unodzorwa pabhiri rekuchaja. Pahub ine peak ye1.2 MW uye mutengo we$15/kW, kuchekwa kwemagetsi kwe300 kW kunochengetedza $54,000 pagore.

Kutamiswa kwemutoroInofambisa kushandiswa kwesimba panguva imwe chete. Bhatiri rinochaja panguva dzisina simba (kana simba riri $0.03–$0.06/kWh) uye rinopa simba rekuchaja panguva dzine simba (kana simba riri $0.15–$0.30/kWh). Kubatsira kwaro kudzikiswa kwemari yesimba pamwe chete, mune mamwe misika, mari inowanikwa nearbitrage.

Tafura iri pazasi inoenzanisa nzira dzacho nekushandisa chinangwa, chinotungamira pakudzora, uye kuchengetedza kwakajairika:

EMS yakanyatsogadziriswa inoita zvimwe zveizvi panguva imwe chete: kubvisa peak, kufambisa mutoro pakati pemahwindo emitero, uye kupindura zviitiko zveDR kana mutengo wakarurama.

Mhinduro yeKudiwa uye V2G: Kuchengetera seGrid Asset

Kupfuura mita, BESS hub inogona kutora chikamu mumabasa egrid anobhadhara kuchinjika. Zvirongwa zveDemand response (DR) zvinobhadhara nzvimbo dzekuderedza kushandiswa—kana simba rekutumira kunze—kana grid iri kumanikidzwa. BESS inokwanisa 240 kW inogona kuderedza mutoro kwemaawa mana inomiririra inoda kusvika 1 MWh yekuchinjika kunogona kutumirwa, inokosha $12,000–$36,000 pagore mumisika yeDR inoshanda.

Mota-ku-grid (V2G) inoenderera mberi nepfungwa imwecheteyo kune marori kana mabhazi pachawo. Nemachaja maviri-directional uye mota dzinoshandiswa neISO 15118, depot inogona kuunganidza mabhatiri emotokari dzakamiswa senzvimbo yemagetsi chaiyo. Izvi zvakaoma kushandisa—zvirambidzo zvekuwanikwa kwemotokari zvinofanira kuremekedzwa—asi zvinoshandura midziyo isingashandiswi zvakanyanya (mabhatiri emotokari akamiswa) kuita mari. Vazhinji vanoshanda vanotanga V2G mushure mekugera zvakanyanya uye DR zvinoratidzwa, sezvo izvo zvisingade kushandira pamwe kwemotokari.

Kuronga Kwakavakirwa paAI uye Kudzora Kufanotaura

EMS yakavakirwa pamitemo isingachinji—"kubuda kubva na4pm kusvika na9pm"—inosiya mari patafura nekuti mitoro chaiyo nemitengo zvinosiyana zuva nezuva. Kudzora kwekufanotaura kunowedzera kufanotaura: EMS inofanotaura kudiwa kwekuchaja mangwana kubva kumagetsi ekufambisa, simba rezuva kubva kudata remamiriro ekunze, uye mutengo kubva kumakarenda emitero, yobva yagadzirisa hurongwa hwebhatiri munzvimbo yese.

Kuvandudzwa kwekudzidza kwemuchina kunoenderera mberi, kudzidza maitiro ewebsite vhiki nevhiki uye kugadzirisa mutemo wekutumira otomatiki. Mhedzisiro inoyerwa panzvimbo dzinoshanda dzinosanganisira:

• Kuderedzwa kwemari yekuwedzera ne10–20%kutumira zvinhu zvichibva pamitemo, kubva panguva iri nani yemabhatiri;
• Mabhatiri mashoma pa kilowatt-awa imwe neimwe anopihwa, kuwedzera hupenyu hwekufamba kwemhepo nekuenzanisa simba rekuburitsa zvinhu nemutoro chaiwo;
• Kuvandudzwa kwekutevedzera mitemo ye peak-cappanguva dzemazuva asina kujairika (mazororo, mafungu ekupisa, zviitiko) izvo zvinorambidza.

Kune [2 MWh 960 kW megawatt BESS charging station] (https://www.midapower.com/2mwh-960kw-bess-charging-station-megawatt-ev-charger-solar-battery-storage-system-product/), uko kutenderera kamwe chete kusina nguva kunogona kudhura mazana emadhora mukuora pamwe nekuwanda kwezvinodiwa, kutonga kwekufanotaura hakusi kweumbozha - ndiyo nzira yekushanda.

Kushanda pamwe chete kweprotocol: OCPP 2.0.1 uye ISO 15118

Nzira dzese dzakangwara dzatsanangurwa pamusoro dzinoenderana nekuti EMS itaure mutauro wakafanana nemachaja nemota. Mitemo mitatu inotsanangura mutauro iwoyo:

• OCPP 2.0.1— chiyero chekuchaja kubva kubhaketi kuenda kubhaketi. Kushanda kwayo kweSmartCharging kunoita kuti EMS igadzire miganhu yesimba repasesheni, kudzora mashandisirwo emari, uye manejimendi yemudziyo kure. Inotsiva OCPP 1.6J kune mahub matsva nekuda kwekuchengetedzeka kuri nani (TLS), kubata zvikanganiso zviri nani, uye kuchaja kwakangwara.
• ISO 15118— mwero wekuti mota ishandise mota imwe chete. Plug & Charge inosimbisa kuti mota yacho ndeyechokwadi, uye nzira iyi inotakura mamiriro ebhatiri remotokari uye zvirambidzo zvekuchaja kuEMS, zvichiita kuti pave nezvikamu zvakagadziriswa pane kuchaja zvine mwero wakatarwa.
• IEC 61851— chiyero cheEVSE chinoshandisirwa nechaja yemazuva ano, uye chinoshandiswa neOCPP neISO 15118.

Kutsanangura zvese zvitatu panguva yekutenga ndiyo inishuwarenzi yakachipa inogona kutengwa nemuridzi wehub. Izvi zvinovimbisa kuti [BESS yezvivakwa zveEV](https://www.midapower.com/news/bess-for-ev-infrastructure-fast-flexible-and-grid-friendly-ultra-fast-charging-solutions/) inogona kufambiswa nechero EMS yemazuva ano, inogona kubatana nezvirongwa zveDR zvemangwana, uye inogona kugamuchira mota kubva kune chero OEM isina adapter workarounds.

Mhedziso

Kutarisira simba nekuchenjera ndiko kunoparadzanisa hub yeBESS kubva mubhatiri. EMS—ine hunyanzvi hwekugera ganda, kutonga mutoro unochinja-chinja, kuronga mitengo, uye nzira dzakavhurika—inoshandura nzvimbo yekuchengetera zvinhu kuita muchina wekuderedza mari uye wekuwana mari uku ichichengetedza charger yega yega ichipa. Vashandi vanofanirwa kukoshesa puratifomu yakabatanidzwa pane kutenga zvikamu, kuisa OCPP 2.0.1 neISO 15118, uye kutanga nekugera ganda usati waisa arbitrage, DR, uye pakupedzisira V2G. Strategy stack yakaratidzwa, inoyerwa, uye inowedzera musiyano uripo pakati penzvimbo yekuchaja inorarama munzvimbo yayo yemitero neiyo inobudirira mairi.
