I-Retrofit Plan yeziteshi ezikhona

Eziteshini ezikhona eziyisisekelo zokuxhumana (ikakhulukazi amagumbi emishini emibhoshongo/izindawo zekhabhinethi ezingaphandle), zuza ukuthuthukiswa okungenakutshalwa kwezimali kumthamo wamandla okulondoloza ikhophi nokongiwa kwamandla ngokusebenzisa izixazululo "ze-photovoltaic + energy storage".

1. Ukubhekana nezinhlungu
   • Amabhethri e-lead-acid anikeza isikhathi sokulondoloza esilinganiselwe (amahora angu-2–3 kuphela)
   • Izindleko zokushintsha ibhethri eziphezulu (cishe ¥4,000 isayithi ngonyaka)
   • Ukushoda kokuqapha kwemvelo kuholela empilweni yebhethri efinyeziwe ngenxa yokwehluleka kwesimo somoya
   • Akwanele ekunqamukeni okuhleliwe (>amahora angu-3)

2. Ukwahlukaniswa Kwezixazululo

(1) Izixazululo ze-DC Energy Storage

• Izici:Ukuxhumeka okuqondile kubha yebhasi engu-48V, akukho ukuguqulwa kwesistimu yokuqala yokuphakelwa kwamandla okudingekayo.
• Izinzuzo:

• Ukubuyisela kabusha okulula, izindleko eziphansi
• Ukuguqulwa okuhlanzekile kwe-DC-DC, ukusebenza kahle okuphezulu (>96%)
• Isixhumi esibonakalayo esigciniwe se-PV ukuze sinwetshwe esikhathini esizayo
• Isekela ukushefa okuphezulu kanye nokugcwaliswa kwesigodi (ukushaja ngesikhathi samahora okungasebenzi, ukushaja ngesikhathi samahora aphezulu/e-spike)

(2) AC Energy Storage Solutions

• Izisetshenziswa eziwumgogodla: Isistimu Yokuguqula Amandla (PCS)

• Imodeli: EPCS15 / EPCS30 (15kW / 30kW)
• Isekela ububanzi bokufaka kagesi obungu-150–750V, obuhambisana namaseli ebhethri angu-280Ah angumthamo omkhulu
• I-Energy Management System (EMS) eyakhelwe ngaphakathi engasindi (i-EMS) esekela i-microgrid, izindlela zokuzikhiqizela wena nezindlela zokuzisebenzisa, nokunye.
  • Izimo ezisebenzayo:Amasayithi adinga ukumbozwa ngasikhathi sinye kokulayishwa kwe-AC (isb., isimo somoya)
  • Izinzuzo:Umthamo omkhulu wokugcina amandla, inzuzo ephezulu ye-peak-to-off-peak arbitrage

3. Ukukhethwa Kwebhethri (Iziteshi Ezikhona)

• Ibhethri ye-lithium eqinile (280Ah)

• Ukuminyana kwamandla ≥165Wh/kg
• Impilo yomjikelezo ifika emijikelezweni engu-26,000 (0.5C, 100% DOD)
• Ukuphepha okuphezulu (i-solid-liquid hybrid electrolyte, ingozi ephansi yomlilo/ukuqhuma)
  • Ibhethri elijwayelekile le-Lithium (100Ah/200Ah)
• Idizayini eyimojuli, ekalayo ifike ku-50kWh ngokuhambisana

4. Amaphuzu Avelele Emodeli Yebhizinisi
   • I-Zero Investment Kwabasebenzi: Ukutshalwa kwezimali kwebhethri, ukusebenza nokunakekelwa, kanye nezindleko zokulahla zikhava nguzakwethu
   • Ukwabelana Ngezindleko zikagesi: Jabulela cishe isaphulelo sika-3% kumanani kagesi
   • Ubude Besikhathi Samandla Esipele Esandisiwe: Kunyuswe kusuka emahoreni angu-2-3 ukuya phezulu 7 amahora
   • Ukufinyelela Kwedatha: Ukunikezwa kwamahhala kokuxhumana kwedatha yemvelo nokusetshenziswa kukagesi

Uhlelo Lokuqinisekisa Ukuphepha (Imikhiqizo Yesitoreji Samandla)

• Ukuqapha ukuphepha kwamaseli ebhethri anamazinga amaningi
• Ukufakwa kwe-thermal okusebenza kahle kakhulu + i-valve yokusiza ingcindezi + ukwakheka okuhlanganisiwe
• Ukucindezelwa komlilo okukhaliphile (isicishamlilo esiqondiswe ku-perfluorohexane)
• Ukulawulwa kokushisa okupholisa uketshezi (ukulawula okuhlukile kwezinga lokushisa okunembile)
• Ukuqapha kokutholwa komlilo ekugcineni kuya ekupheleni

Izixazululo Zesimo Sesicelo Esijwayelekile

Isimo 1: Amandla Egridi + Isitoreji Samandla Esiyisipele

• Izingxenye: Amandla amakhulu + Ibhethri + Ukuqapha kwe-FSU
• Umsebenzi: Inikeza amandla ngesikhathi sokusebenza kwamapayipi amakhulu; inikeza amandla ekhophi yasenqolobaneni yesikhashana ngesikhathi sokunqamuka kwamapayipi amakhulu
• Izicelo: Iziteshi zasemadolobheni, izindawo ezinamagridi kagesi azinzile

Isimo sesi-2: Amandla egridi + Isitoreji Samandla + Ijeneretha Yedizili

• Izingxenye: Amandla amakhulu + Ibhethri + Ijeneretha yeDizili + FSU
• Umqondo: Amandla kagesi → Ibhethri → Ijeneretha yedizili (ukuvikelwa kwezigaba ezintathu)
• Isicelo: Izindawo ezikude ezinamandla kagesi kodwa zihamba ngezikhathi ezithile

Isimo 3: I-PV + Amandla Egridi + Isitoreji Samandla + Ijeneretha Yedizili (IHybrid Egcwele)

• Amandla Abalulekile Abalulekile: I-PV > Amandla Egridi > Ibhethri > Isiphehlisi Sedizili
• Izingxenye: I-Rectifier Power Supply + Ikhabhinethi Yamandla e-PV + Ibhethri + I-Dizeli Generator + FSU
• Ifanele: Izindawo ezingenawo amandla egridi azinzile nokukhanya kwelanga okwanele (isb., amathafa, iziqhingi)

Isimo 4: I-Photovoltaic + Isitoreji Samandla + Ijeneretha Yedizili (Uhlobo Lwe-Off-Grid)

• Alukho uxhumano lwegridi; ukuthembela ngokugcwele kumandla avuselelekayo + isipele sejeneretha yedizili
• Okusemqoka: Ilanga > Ibhethri > Ijeneretha yeDizili (DC)
• Isebenza: Amasayithi okuxhumana angaphandle kwegridi ngokugcwele
