Ungaxazulula Kanjani Ukucindezeleka Kwekhono Legridi Yeziteshi Zokushaja Okusheshayo?

Impendulo Esheshayo

Ukuxazulula ingcindezi yomthamo wegridi yeziteshi zokushaja okusheshayo kudinga indlela enezingqimba eziningi:Izinhlelo Zokugcina Amandla Ebhethri (BESS)isebenza njenge-buffer yokushefa imithwalo ephezulu,Ukulinganisela Umthwalo Oguquguqukayoyenza ngcono ukusatshalaliswa kwamandla kuzo zonke izihlinzeki eziningi, futhiAma-algorithm okushaja ahlakaniphileisidingo sokushintsha ngokusekelwe kumasignali egridi. Ngokuhlanganisa isitoreji, opharetha bangasebenzisa amashaja ashesha kakhulu (360kW+) ngisho nakumagridi akhawulelwe ku-100kW, okunciphisa kakhulu izindleko zokuthuthukisa ingqalasizinda kanye nezimali zegridi.

Izinto Ezibalulekile Okufanele Uzicabangele

• I-BESS Buffering: Izinhlelo zokugcina zikhishwa ngesikhathi seseshini ephezulu, okuvumela ukushaja kwamandla aphezulu ngaphandle kokudlula imikhawulo yegridi.
• Ukushefa Okuphakeme: Kunciphisa izindleko zokufunwa ngokuvala amandla aphezulu athathwe kuhlelo lokusebenza.
• Ukwabelana Ngomthwalo Oguquguqukayo: I-logic yokwabiwa okuhlakaniphile kwe-MIDA isabalalisa amandla phakathi kwezibhamu ngokusekelwe ezicelweni ze-BMS zezimoto zesikhathi sangempela.
• Ukusebenza kahle: Ama-PCS asekelwe ku-SiC (Amasistimu Okuguqula Amandla) afinyelela ukusebenza kahle okungu-≥97.1%, okunciphisa imfucuza yamandla.
• Ukuthobela imithetho: Ihambisana ngokugcwele ne-ISO 15118-20 ye-V2G kanye nokusebenzisana kwegridi ehlakaniphile.
• Ukuqinisekisa Ikusasa: Isekela amapulatifomu e-voltage ephezulu angu-1000V kanye nokupholisa uketshezi ukuze kushajwe i-500A+.
• Imali engenayoIzinhlelo ezihlanganisiwe zivumela ukubamba iqhaza kwempendulo yesidingo, ziguqula ukuphathwa kwamandla kube yisikhungo senzuzo.

Ukucwila Okujulile: Ukuxazulula Inkinga Yegridi

1. Inselele: Isidingo Esiphezulu vs. Ingqalasizinda Yegridi

Njengoba ukwamukelwa kwe-EV kukhula, isidingo samashaja asheshayo angu-360kW kanye no-480kW siyanda. Kodwa-ke, izindawo eziningi zasemadolobheni kanye nemigwaqo emikhulu zibhekene nemingcele yegridi, lapho ama-transformer endawo engakwazi ukusekela amaseshini anamandla aphezulu ngasikhathi sinye. Ukuthuthukiswa kwegridi yendabuko kuhamba kancane, kuyabiza, futhi kuvame ukuhilela ukuvunyelwa okuyinkimbinkimbi kwemithetho.

2. I-BESS njenge-“Power Reservoir”

UkuhlanganisaIzinhlelo Zokugcina Amandla Ebhethri (BESS)ivumela abaqhubi beziteshi ukuthi "bagcine" amandla ngezikhathi zokudingeka okuncane futhi "bawakhulule" lapho imoto ixhuma.

• Isibonelo: Indawo enoxhumano lwegridi engu-100kW ingasekela iseshini yokushaja engu-360kW ngokudonsa i-100kW kusuka kugridi kanye ne-260kW kusuka ku-BESS.
• Inzuzo ye-TCOLokhu kuqeda isidingo sokuthuthukiswa okukhulu kwe-transformer, okungabiza ngaphezu kuka-$100,000 endaweni ngayinye.

3. Ukulinganisela Umthwalo Oguquguqukayo Nokushaja Okuhlakaniphile

Ama-MIDAIziteshi zokushaja okusheshayo ze-DC ezingama-480kWsebenzisa amamojula wamandla ahlakaniphile angabiwa ngendlela eguquguqukayo. Uma izimoto ezimbili zishaja, uhlelo lubeka phambili leyo ene-State of Charge (SoC) ephansi noma lusabalalise amandla ngokulinganayo, ukuqinisekisa ukuthi inani eliphelele alidluli umkhawulo wesayithi.

4. Ukuhlanganiswa Kwelanga kanye nama-Micro-grid

Ukuhlanganisaizinhlelo zokushaja ze-EV zesitoreji selanga kanye nesitorejikudala indawo yegridi encane. Amandla elanga anika amandla ngqo amashaja noma ashaje i-BESS, okunciphisa kakhulu ukuthembela kugridi futhi kunciphisa ukuqina kwekhabhoni.

Imibuzo Evame Ukubuzwa

1. Iyiphi indlela engabizi kakhulu yokusingatha imikhawulo yegridi?Ukuhlanganiswa kwe-BESS kuyisisombululo esisebenza kahle kakhulu, njengoba kuvumela ukushefa okuphezulu futhi kugwema izindleko eziphezulu zokwandiswa kwegridi.

2. Ngingafaka ishaja engu-360kW kugridi engu-150kW?Yebo, ngokusebenzisa isisombululo esihlanganisiwe se-BESS, unganciphisa amandla futhi unikeze amandla angu-360kW ngenkathi udonsa amandla angu-150kW kuphela kuhlelo lokusebenza.

3. Ingabe ukushaja okuhlakaniphile kuyayithinta ijubane lokushaja?Ukushaja okuhlakaniphile kuthuthukisa isivinini ngokusekelwe empilweni yegridi kanye ne-BMS yemoto, okuqinisekisa ukushaja okusheshayo ngangokunokwenzeka ngaphakathi kwemikhawulo yokuphepha kanye nomthamo.

4. I-BESS isiza kanjani ekunciphiseni izikweletu zikagesi?Kuyasiza ngokunciphisa "izindleko zokufunwa" — izimali ezisekelwe ekusebenziseni kwakho amandla okuphezulu kakhulu — ngokuvala ukudonsa okuphezulu kusuka kugridi.

5. Ingabe ikhambi le-MIDA liyahambisana nelanga?Impela. I-MIDA inikeza i-integratedIziteshi zokushaja ze-BESSyakhelwe ukuxhumanisa i-DC yelanga engenamthungo.

6. Yiziphi izindinganiso ezilandelwa yilezi zinhlelo?Zihambisana ngokugcwele ne-IEC 61851-23 futhi zisekela i-ISO 15118-20 yokuxhumana kwegridi okuthuthukisiwe.

7. Ingabe lezi zinhlelo zinganikeza amandla okusekela?Yebo, okwethuIzixazululo zokushaja ze-V2Gisekela imodi yokubeka phansi amandla okusekelayo ngesikhathi sokungasebenzi.
