Iqhutywa ziinjongo "zekhabhoni ephindwe kabini" (i-carbon peaking kunye nokungathathi hlangothi kwekhabhoni), imboni ye-photovoltaic yaseTshayina ifumana utshintsho olungazange lubonwe ngaphambili kunye nokutsiba.Kwikota yokuqala ka-2024, i-photovoltaic entsha yokuvelisa amandla egridi yegridi-eqhagamshelwe umthamo wafikelela kwi-45.74 yezigidi zeekilowatts, kunye nomthamo odibeneyo wegridi we-cumulative wadlula i-kilowatts yezigidi ezingama-659.5, ephawula ukuba imboni ye-photovoltaic ingene kwinqanaba elitsha lophuhliso.Namhlanje, siza kuphonononga nzulu ukubunjwa kunye nokuhlelwa kwegridi-exhunyiwe kwiinkqubo zokuvelisa amandla e-photovoltaic.Nokuba "kukusebenzisa ngokwakho amandla e-photovoltaic asasaziweyo kunye negridi edityaniswe nentsalela yamandla", okanyeuqhagamshelwano lwegridi enkuluye-photovoltaic ephakathi.Ungabhekisa kuyo ngokusekelwe kumxholo wombhalo.
Ukuhlelwa kweigridi-iqhagamshelweiinkqubo zokuvelisa amandla e-photovoltaic
Iinkqubo zokuvelisa amandla e-photovoltaic ezidityanisiweyo zegridi zinokwahlulwa zibe ziinkqubo ezidityanisiweyo zegridi ezichaseneyo, iinkqubo ezidityanisiweyo ezingenayo i-non-countercurrent, ukutshintshwa kweenkqubo ezidityanisiweyo zegridi, i-DC kunye ne-AC edityaniswe ne-AC, kunye neenkqubo ezidityanisiweyo zegridi zengingqi ngokuhambelana nokuba umbane amandla athunyelwa kwinkqubo yamandla.
1. Inkqubo yokuvelisa umbane edibana negridi edibeneyo
Xa amandla aveliswa yinkqubo yokuvelisa amandla elanga photovoltaic anele, amandla aseleyo angathunyelwa kwigridi yoluntu;xa amandla anikezelwe yinkqubo yokuvelisa amandla elanga photovoltaic ayanelanga, igridi yamandla inika amandla kumthwalo.Ekubeni amandla anikezelwa kwigridi kwicala elichaseneyo negridi, ibizwa ngokuba yinkqubo yokuvelisa amandla e-photovoltaic countercurrent.
2. Inkqubo yokuvelisa umbane eqhagamshelwe kwigridi ngaphandle kokunye
Nangona inkqubo yokuvelisa amandla elanga ye-photovoltaic ivelisa amandla aneleyo, ayinikezeli amandla kwigridi yoluntu.Nangona kunjalo, xa inkqubo yokuvelisa amandla elanga ye-photovoltaic inika amandla anganeleyo, iya kunikwa amandla yigridi yoluntu.
3. Ukutshintsha inkqubo yokuvelisa umbane eqhagamshelwe kwigridi
Inkqubo yokuvelisa amandla egridi edibeneyo inomsebenzi wokutshintsha okuzenzekelayo ngeendlela ezimbini.Okokuqala, xa inkqubo yokuvelisa amandla e-photovoltaic ivelisa amandla anganeleyo ngenxa yemozulu, ukungaphumeleli kokumhlophe, njl., umtshintshi unokutshintshela ngokuzenzekelayo kwicala lonikezelo lwamandla egridi, kwaye igridi yamandla inika amandla kumthwalo;okwesibini, xa igridi yamandla ngokukhawuleza ilahlekelwa amandla ngenxa yesizathu esithile, inkqubo yokuvelisa amandla e-photovoltaic Iyakwazi ukutshintshela ngokuzenzekelayo ukwahlula igridi yamandla ukusuka kwinkqubo yokuvelisa amandla e-photovoltaic kwaye ibe yinkqubo yokuvelisa amandla e-photovoltaic ezimeleyo.Ngokuqhelekileyo, ukutshintsha igridi-edityaniswe ne-photovoltaic iinkqubo zokuvelisa amandla zixhotyiswe ngezixhobo zokugcina amandla.
4. Igridi yokugcina amandla edityaniswe nenkqubo yokuvelisa amandla
Inkqubo yokuvelisa amandla e-photovoltaic edibeneyo yegridi kunye nesixhobo sokugcina amandla kukulungisa isixhobo sokugcina amandla ngokweemfuno kwiindidi ezikhankanywe ngasentla ze-grid-ezixhunyiwe kwiinkqubo zokuvelisa amandla e-photovoltaic.Iinkqubo ze-Photovoltaic ezinezixhobo zokugcina amandla zisebenza kakhulu kwaye zinokusebenza ngokuzimeleyo kwaye zinikeze amandla kumthwalo ngokuqhelekileyo xa kukho ukuphuma kwamandla, umda wamandla okanye ukungaphumeleli kwigridi yamandla.Ngoko ke, inkqubo yokuvelisa amandla e-photovoltaic edibeneyo yegridi kunye nesixhobo sokugcina amandla ingasetyenziselwa njengenkqubo yokubonelela umbane kwiindawo ezibalulekileyo okanye imithwalo engxamisekileyo njengombane wonxibelelwano olungxamisekileyo, izixhobo zonyango, izikhululo zegesi, isibonakaliso sendawo yokukhupha kunye nokukhanyisa.
5. Isixokelelwano sombane esikhulu esiqhagamshelwe kwigridi
Inkqubo yokuvelisa amandla e-photovoltaic yegridi enkulu idityaniswe ziiyunithi ezininzi zokuvelisa umbane we-photovoltaic.Iyunithi nganye yokuvelisa amandla e-photovoltaic iguqula amandla e-DC aveliswa luluhlu lweseli yelanga ibe yi-380V AC amandla ngokusebenzisa i-photovoltaic grid-eqhagamshelwe inverter, kwaye emva koko ijike ibe yi-10KV AC yamandla aphezulu-voltage ngokusebenzisa inkqubo ye-booster.Emva koko ithunyelwa kwinkqubo ye-35KV ye-transformer kwaye idibaniswe kumandla we-35KV AC.Kwigridi yamandla e-high-voltage, i-35KV AC i-high-voltage power iguqulwa ibe yi-380 ~ 400V AC amandla ngokusebenzisa inkqubo ye-step-down njenge-backup power supply yesikhululo samandla.
6. Inkqubo yokuvelisa amandla asasaziweyo
Inkqubo yokuvelisa amandla e-photovoltaic esasazwayo, ekwabizwa ngokuba yimveliso yamandla asasaziweyo okanye unikezelo lwamandla asasazwayo, ibhekisa kulungiselelo lweenkqubo ezincinci zobonelelo lwamandla ephotovoltaic kwindawo yomsebenzisi okanye kufutshane nesiza sokusetyenziswa kwamandla ukuhlangabezana neemfuno zabasebenzisi abathile kunye nokuxhasa uqoqosho lwe-photovoltaic. uthungelwano olukhoyo losasazo.ukusebenza, okanye zombini.
7. Inkqubo ye-Microgrid ehlakaniphile
I-Microgrid ibhekiselele kumbane omncinci wokuvelisa kunye nenkqubo yokusabalalisa eyenziwe ngamajelo asasazwayo ombane, izixhobo zokugcina amandla, izixhobo zokuguqula amandla, imithwalo ehambelanayo, ukubeka iliso kunye nezixhobo zokukhusela.Yinkqubo enokuqonda ukuzeyisa, ukhuselo nokhuseleko.Inkqubo yokuzimela elawulwayo inokusebenza ngokubambisana negridi yamandla yangaphandle okanye ngokuzimeleyo.I-microgrid ixhunyiwe kwicala lomsebenzisi kwaye ineempawu zexabiso eliphantsi, i-voltage ephantsi kunye nokungcola okuphantsi.I-microgrid inokudibaniswa kwigridi yamandla amakhulu, okanye inokuqhawulwa kwigridi eyintloko kwaye iqhube ngokuzimeleyo xa igridi yamandla ihluleka okanye iyadingeka.
Ukuqulunqwa kwenkqubo yokuvelisa amandla e-photovoltaic kwigridi
I-photovoltaic array iguqula amandla elanga kumandla e-DC, idibanise ngebhokisi yokudibanisa, kwaye iguqule amandla e-DC kumandla e-AC ngokusebenzisa i-inverter.Umgangatho wombane wesikhululo samandla e-photovoltaic esiqhagamshelwe kwigridi yamandla simiselwa ngokomthamo wesikhululo samandla se-photovoltaic esichazwe buchwephesha bokudibanisa isikhululo samandla e-photovoltaic kwigridi yamandla., emva kokuba i-voltage iphakanyiswe yi-transformer, ixhunyiwe kwigridi yamandla kawonkewonke.
