Iziphumo ezinjani ezizovutha uma i-PV ihlangana ne-ESS (ESS) bese ixhuma ne-EV Charging?

Uhlelo oluhlanganisiwe lwe-PV+ESS+EV Charging luba "isixazululo esikhulu" sokunciphisa ingcindezi yenethiwekhi nokuthuthukisa ukusebenza kahle kwamandla. Uhlelo oluhlanganisiwe lwe-PV+ESS+EV Charging luhlanganisa uhlelo oluncane lwe-microgrid oluhlanganisa imithombo yamandla ye-PV esatshalaliswe, ama-ESS, izinto zokulawula ukushaja nokukhipha, kanye nezindawo zokusabalalisa. Luhlanganisa ngokuhlangana izigaba ezintathu ezinkulu zobuchwepheshe: ukukhiqizwa kwamandla e-PV, ukugcinwa kwamandla okubuyisela emuva, nokushaja okuhlakaniphile. Leli phepha lizokwenza ukuhlaziya okujulile kwezinto ezintathu eziyinhloko zalolu hlelo, livulekele ukuthi zisebenza kanjani ngokuvumelana, njengezinyathelo zamagiya ezihlangene ngokunembayo, ukwakha ikusasa lamandla ahlanzekile, ahlakaniphile, futhi ahlakaniphile.

Umsebenzi omkhulu: Ngemithombo ye-semiconductor kumaphaneli e-PV, amandla elanga aguqulwa kahle abe ugesi ohlanzekile, ubeka isisekelo samandla sohlelo lonke.

Ukuhlaziywa kwezobuchwepheshe: Izinhlelo ze-PV zingahlukaniswa zibe izinhlobo ezixhunyiwe ku-grid nezizimele. Uhlelo oluxhunyiwe ku-grid luhlanganisa kakhulu izingxenye ezibalulekile ezifana namaphaneli e-PV, izakhiwo ezisekelayo, amakhebuli kanye nezinguquko ezixhunyiwe ku-grid. Isici sayo esiyinhloko ukuthi ugesi okhiqizwayo udluliselwa ngqo ku-grid yamandla omphakathi. Ngokuphambene, uhlelo olungaxhunyiwe ku-grid luhlanganisa amaphakheji ebhethri kanye nezilawuli zokushaja-nokukhishwa ngaphezu kwezingxenye zohlelo oluxhunyiwe ku-grid, okuvumela ukugcina ugesi ngokuzimela nokusetshenziswa.

Umehluko oyisisekelo phakathi kwalezi zinhlelo ubhekisela ekubeni khona noma ekungabikhona kwesikhala sokugcina amandla. Phakathi nenqubo yokuguqulwa kwamandla, imodyuli ye-PV iqala uguqule amandla elanga abe yikurrenti eqondile (DC), bese iguqulwa yi-inverter ibe yikurrenti ephindaphindayo (AC) ehambisana nezindinganiso ze-grid. Le ndlela yokuguqula amandla iyisisekelo somgomo wezobuchwepheshe bokukhiqiza amandla e-PV.

Indima eyinhloko: Umsebenzi oyinhloko we-ESS ukuvumela ukudluliswa kwesikhathi nendawo kwamandla kagesi, ukusiza ngempumelelo ukuxazulula ukungahambisani phakathi kokukhiqizwa kwamandla nokusetshenziswa.

Ukuhlaziywa kwezobuchwepheshe: Umqondo wokusebenza kwe-ESS ungafaniswa kahle nokuthi "ibhange lamandla elikhulu", eligcina ugesi owengeziwe owenziwe ngokuqhuba amandla e-PV ngephakheji ye-battery futhi ukhipha ngesikhathi sokudinga ugesi okuphezulu. Ngesikhathi sokuthi ukuhlinzekwa kwamandla e-PV kudlula izidingo ezikhona, i-ESS ingena emodenini yokushaja. Ngokuphambene, lapho udinga ugesi kukhuphuka noma ukuhlinzekwa kwamandla e-photovoltaic kunganele, kushintsha emodenini yokukhishwa, kuguqula amandla agcinwe abuyele ekukhipheni ugesi. Le "modes yokugcina ephansi, yokukhulula ephezulu" ayigcini nje ngokufeza ukusika umthwalo ophakeme nokugcwalisa izigodi, kodwa futhi ivumela izinzuzo ezivela ekuhlukaniseni amanani kagesi phakathi kokuphakela nokudinga ngokubamba iqhaza ezimakethe zamandla. Ngaphezu kwalokho, inciphisa ukungqubuzana kokuhlinzekwa-dinga ngemuva komsebenzisi, yehlisa ukutshalwa kwezimali kwezinsiza zokukhiqiza ugesi, ikhuphule amazinga okusetshenziswa kwezinsiza zamandla, futhi inciphise ukulahleka kwemigqa.

Indima eyinhloko:

Njengoba iyinxenye yokugcina esixazululweni sokugcina nokushaja i-photovoltaic, indima eyinhloko yesistimu yokushaja ukuhlinzeka ngokusabalalisa kahle nokuhlela okuhlakaniphile kwamandla kagesi.

Ukuhlaziywa kwezobuchwepheshe:

I-station ye-PV ikhiqiza amandla ngokuhambisana nomgomo wesistimu yokukhiqiza amandla e-PV exhunywe ku-grid. Amandla kagesi aguqulwe kusukela kumandla elanga ngezi-module ze-PV awadluliselwa kuphela ebhathini ukuze agcinwe nge-PV charging controller, kodwa futhi adluliselwa ku-grid nge-inverter exhunywe ku-grid. Ngale ndlela, ingxenye yamandla kagesi isetshenziselwa ukushaja ama-EV, kanti enye ingxenye iguqulwa futhi ifakwe ku-grid. Ngaphezu kwalokho, ama-station e-PV angasebenza futhi njengemithombo yamandla yokusekela ezindaweni zokusebenza zomgwaqo.

Lapho i-unit yokubheka ohlelweni ithola ukuphazamiseka kwenethiwekhi nokuphuma kukagesi, ingakwazi ukususa ngokushesha uhlelo kunethiwekhi kagesi futhi iqale ngokushesha i-inverter yokuhlinzeka ngogesi ngaphandle kwenethiwekhi. Lapho inethiwekhi ibuyela esimweni esijwayelekile, uhlelo lungashintsha lube esimweni sokusebenza esijwayelekile.

Iziteshi Zamandla Ezingu-5

Incazelo eningiliziwe yezigaba eziyisihlanu ezinkulu

Circuit 1

Ukuze kuqinisekiswe indima yokugcina amandla ekukhiqizeni amandla e-PV: I-DC eguqulwe kusuka kumandla elanga igcinwa kuphakeji ye-battery nge-controller ehlakaniphile.

Circuit 2

Ukuze kufezwe umsebenzi wokuxhuma i-inverter ku-grid ye-battery pack ku-ESS: Igesi kagesi egciniwe ku-battery pack ku-ESS iguqulwa ibe yi-AC nge-inverter bese ifakwa ku-grid yamandla.

Circuit 3

Lo mjikelo ufinyelela ukukhiqizwa kwamandla okuxhumene nenethiwekhi kohlelo lwe-photovoltaic. Amandla e-DC akhiqizwa yi-PV module aguqulwa abe yi-AC bese edluliselwa enethwekhi. Uma kukhona amandla e-PV anele, angathengiswa enethwekhi ngale mjikelo ukuze kukhiqizwe inzuzo yezomnotho. Qaphela ukuthi ama-inverter kuMjikelo 2 no-3 ayabelwana, ngakho-ke lezi zimbili mjikelo azikwazi ukusebenza ngesikhathi esisodwa.

Circuit 4

Ithola ukuhlinzekwa kwamandla kwe-ESS: amandla agcinwe agcinwa ku-grid ngokusebenzisa ukuguqulwa kwezinyathelo ezimbili (DC/DC kanye ne-DC/AC), kusebenze njengomjikelezo wokuhlinzeka ngamandla wesekelo uma i-inverter enkulu itholakala. Uma i-Circuit 3 ivuliwe, amandla agcinwe ebhathini angahlinzekwa ku-grid ngokusebenzisa i-Circuit 4.

Circuit 5

Lo mjikelezo uvumela umsebenzi wokushaja ophumayo. Uma intengo kagesi yegridi iphansi kunezinga elijwayelekile lentengo kagesi yegridi, i-ESS ingathola ugesi ku-grid ngeCircuit 5 ukuze izishaje, ikwazi ukusebenzisa umehluko wentengo.

Ngokuthuthuka kwezobuchwepheshe kanye nezinhlelo zokweseka, imodeli ye-PV-ESS-Charging ibhekene nokuba ingxenye ebalulekile yohlelo lwamandla olusha, ihlinzeka ngoxhaso oluqinile ekufezeni izinhloso zokuba ne-carbon neutrality. Masilindele ngentshiseko leli thuba lamandla aluhlaza likhanya kakhulu esikhathini esizayo.
