Kutheni le nto isisombululo sonikezelo lwamandla enkampini sibalulekile?
Umbane ozinzileyo ongekho kwigrid uyafuneka kwiindawo ezikude zemigodi, iindawo zolwakhiwo lohola wendlela kunye neendawo ekuchithelwa kuzo iiholide.
Kukho iindlela ezimbini eziphambili zobugcisa okwangoku: ukwakhiwa kwegridi ngabavelisi bedizili kunye nokwenza igridi nge-PV-energy-storage systems.
Eli nqaku lithelekisa izisombululo ezimbini ukusuka kwimilinganiselo emine: indlela yobugcisa, iimeko ezisebenzayo, iindleko kunye nokuzinza.
Ukwenziwa kweGridi nguMvelisi weDizili
Indlela yobuGcisa: Ijeneretha yedizili enolawulo lwamandla ombane we-AVR, yamkele inkxaso yamandla ombane.
Imeko Esebenzayo: Iinkampu zokwexeshana ezinobude bexesha lokwakha elingaphantsi kweenyanga ezi-6, iziza ezinokukhanya kwelanga okungonelanga, okanye iiprojekthi ezifuna umbane ongxamisekileyo.
Uhlalutyo lweendleko: Ixabiso lokuqala eliphantsi lokuthenga (iyunithi engama-30kW: malunga ne-$4,434‑7,390). Iindleko zokusebenza zonyaka zokuvelisa i-diesel zijikeleze i-65,000 yeedola (i-diesel fuel + ukugcinwa). Ukuthuthwa kwepetroli kunzima kwiindawo ezikude, nto leyo enokukhokelela ngokulula ekunqongophelweni kwamafutha.
Uzinzo: Kwisisombululo se-diesel-generator: ukuguquguquka kwamandla ombane ≤ ± 5%, ukuguquguquka rhoqo ≤ ± 0.2Hz. Ixesha lokuphendula elicothayo (5-6s), umthamo obuthathaka wokumelana noxinzelelo lwangoku (3-5 amaxesha omthwalo) ngexesha lokuqalisa kwemoto. Umsebenzi wokuqalisa omnyama awufumaneki emva kokucinywa kwegridi yamandla.
Ukwenziwa kweGridi ngePV‑Energy‑Storage System
Indlela yobuGcisa: Ibhetri ye-Photovoltaic + i-lithium-iron-phosphate + i-off-grid PV inverter + inkqubo yolawulo lwamandla e-microgrid (EMS). Ijenereyitha yedizili isetyenziswa kuphela njengomthombo wamandla ogcinayo.
Imeko Esebenzayo: Iinkampu zexesha elide ezinexesha lokusebenza ngaphezu konyaka omnye, ukusetyenziswa kwamandla emihla ngemihla ngaphezu kwe-300kWh, iisayithi ezinokukhanya okwaneleyo kwelanga, okanye iiprojekthi ezixhomekeke kwiimfuno zovavanyo lokukhutshwa kwekhabhoni.
Uhlalutyo lweendleko: Utyalo-mali lokuqala oluphezulu (20kW PV + 167kWh ugcino lwamandla: malunga ne-$52,000‑74,000); iindleko zokusebenza ngonyaka $35,000. Ixabiso elilinganayo lamandla yi-$0.11‑0.16/kWh kuphela.
Xa kubandakanywa ukusetyenziswa kwe-diesel engxamisekileyo, iindleko zonyaka malunga ne-6,207 yeedola, ezimele ukunciphisa iindleko ze-90.1%. Ixesha lokuhlawula lidla ngokuba yiminyaka emi-3-5.
Uzinzo: Kwisisombululo se-PV‑-energy-storage: ukuguquguquka kwamandla ombane ≤ ± 3%, ukuguquguquka kwamaxesha ≤ ± 0.1Hz; ixesha lokutshintsha imithombo emininzi ≤10ms. Inika impendulo ekhawulezayo, ulawulo oluchanekileyo kunye nomgangatho ophezulu wobonelelo lwamandla.
Iingcebiso zoKhetho
Iindleko zizonke kumjikelo weminyaka emi-5 wobomi obupheleleyo: malunga. I-$ 350,000 yesisombululo se-diesel-generator; malunga. I-$97,000 yesisombululo se-PV-energy-storage, kunye ne-74.2% yokunciphisa ixabiso lilonke lokhetho lwe-PV-energy-storage.
Uhlahlo lwabiwo-mali oluluqilima, ixesha elifutshane leprojekthi, ukungonelanga kwelanga: Khetha igridi eyenziwe nge-diesel-generator.
Landela ukonga iindleko zexesha elide, gxininisa ukhuseleko lokusingqongileyo, ukukhanya kwelanga okwaneleyo: Khetha igridi eyenziwe ngePV-energy-storage-formed.
Isisombululo esisiso: Yamkela "i-PV-energy-storage-diesel" imowudi yegridi encinci. Amandla abonelelwa yiPV ngeentsuku ezinelanga, ngokugcinwa kwamandla ngeentsuku ezinamafu, kunye nejenereyitha yedizili iyasebenza kuphela phantsi kweemeko zemozulu ezimandundu.
