Isingeniso: Kusukela Kumbono Wezwe Langempela Kuya Kulawulo Lokugeleza Kwamandla Okulwa Nokubuyela Emuva
Ngemva kokuqonda izimiso ezingemuvaakukho ukuthunyelwa ngaphandlefuthiukukhawulela amandla ashukumisayo, abaklami abaningi bezinhlelo basabhekene nombuzo osebenzayo:
Uhlelo lokugeleza kwamandla oluphikisana nokubuyela emuva lusebenza kanjani ngempela ekufakweni kwangempela kwelanga endlini?
Empeleni, ukugeleza kwamandla okuphikisana nokubuyela emuva akufezwa ngedivayisi eyodwa. Kudingaukwakheka kwesistimu okuhlanganisiweokubandakanya ukulinganisa, ukuxhumana, kanye ne-logic yokulawula. Ngaphandle komklamo wesistimu ocacile, ngisho nama-inverter ahlelwe kahle angase ahluleke ukuvimbela ukuthunyelwa kwegridi okungahlosiwe ngaphansi kwezimo zomthwalo oguquguqukayo.
Lesi sihloko sethulaisifundo sendawo yokuhlala esivamile se-solar, echaza ukuthi ukulawula ukugeleza kwamandla okulwa nokubuyela emuva kusebenza kanjani ezingeni lesistimu nokuthi kunganiUkulinganisa amandla ngesikhathi sangempela endaweni yokuxhuma igridi kubalulekile.
Isimo Esijwayelekile Se-PV Yendlu Edinga Ukulawulwa Okuphambene Nezimo
Cabanga ngekhaya lomndeni owodwa elihlonyiswe ngalokhu okulandelayo:
-
Uhlelo lwe-PV lwelanga oluphahleni
-
I-inverter exhunywe kugridi
-
Imithwalo yasekhaya enokuguquguquka okuvamile
-
Imithethonqubo yezinsizakusebenza evimbela ukuthunyelwa kukagesi kwamanye amazwe
Ezimweni ezinjalo, ukusetshenziswa kwekhaya kungase kwehle ngokuzumayo—ngokwesibonelo, lapho izinto zikagesi zicima—ngenkathi ukukhiqizwa kwe-PV kuhlala kuphezulu. Ngaphandle kokulawula okuguquguqukayo, amandla amaningi azobuyela emuva kugridi ngemizuzwana.
Ukuvimbela lokhu kudingaimpendulo eqhubekayo kanye nempendulo esheshayo, hhayi ukucushwa okungaguquki.
Ukubuka Konke Kwesakhiwo Sesistimu: Izingxenye Eziyinhloko
Uhlelo lokugeleza kwamandla olunamandla oluphikisana nokuhlehla luvame ukuba nezingqimba ezine ezisebenzayo:
-
Isendlalelo Sokulinganisa Igridi
-
Isendlalelo Sokuxhumana
-
Isendlalelo Sokulawula I-Logic
-
Isendlalelo Sokulungiswa Kwamandla
Isendlalelo ngasinye sidlala indima ethile ekugcineni ukuhambisana nokuqina kohlelo.
Isendlalelo 1: Ukulinganiswa Kwamandla Egridi Yesikhathi Sangempela
Esisekelweni sohlelo kukhonaukulinganisa kwesikhathi sangempela endaweni yokuhlanganisa okuvamile (i-PCC).
Imitha yamandla ehlakaniphile efakwe ekuxhumaneni kwegridi iqhubeka nokulinganisa:
-
Amandla angenisiwe
-
Amandla athunyelwe kwamanye amazwe
-
Isiqondiso sokugeleza kwamandla e-Net
Lokhu kulinganisa kumele kube:
-
Kunembile
-
Okuqhubekayo
-
Kushesha ngokwanele ukukhombisa izinguquko zomthwalo
Ngaphandle kwalolu lwazi, uhlelo alukwazi ukunquma ukuthi ngabe ukugeleza kwamandla okuphambene kuyenzeka yini.
Isigaba 2: Ukuxhumana Phakathi Kwemitha Nesistimu Yokulawula
Idatha yokulinganisa kumele idluliselwe ohlelweni lokulawula ngokubambezeleka okuncane.
Izindlela zokuxhumana ezivamile zifaka:
-
I-WiFikwamanethiwekhi ezindawo zokuhlala
-
I-MQTTukuhlanganiswa nezinhlelo zokuphathwa kwamandla
-
I-Zigbeekwezakhiwo ezisekelwe esangweni lendawo
Ukuxhumana okuzinzile kuqinisekisa ukuthi impendulo yamandla ifinyelela ku-logic yokulawula cishe ngesikhathi sangempela.
Isigaba 3: I-Control Logic kanye Nokwenza Izinqumo
Uhlelo lokulawula—olusetshenziswa kusilawuli se-inverter noma ohlelweni lokuphatha amandla—luhlala luhlola impendulo yamandla egridi.
I-logic ejwayelekile ihlanganisa:
-
Uma ukuthekelisa > 0 W → kunciphisa umphumela we-PV
-
Uma ukungenisa > umkhawulo → vumela ukwanda kwe-PV
-
Faka ukushelela ukuze ugweme ukunyakazisa
Lo mqondo uqhubeka njalo, wakhauhlelo lokulawula oluvaliwe.
Isendlalelo 4: Ukulungiswa Kokukhipha kwe-PV
Ngokusekelwe ezinqumweni zokulawula, i-inverter ilungisa ngokuguquguqukayo umphumela we-PV:
-
Ukunciphisa ukukhiqizwa ngesikhathi somthwalo ophansi
-
Ukwanda komkhiqizo lapho isidingo semindeni sikhuphuka
-
Ukugcina ukugeleza kwamandla egridi ku-zero noma eduze no-zero
Ngokungafani nezilungiselelo zokuthumela ngaphandle kwe-static zero, le ndlela ivumela uhlelo ukuthi luphendule ezimweni zangempela.
Lapho I-Smart Energy Meter Ifaneleka Khona: Indima ye-PC321
Kulolu hlaka lwezakhiwo,I-PC321imitha yamandla ehlakaniphileisebenza njengeihange lokulinganisa lohlelo lonke.
I-PC321 inikeza:
-
Ukulinganisa kwesikhathi sangempela kokungenisa nokuthumela igridi
-
Izibuyekezo zedatha ezisheshayo ezifanelekela ama-loop okulawula aguqukayo
-
Ukuxhumana nge-I-WiFi, i-MQTT, noma i-Zigbee
-
Isikhathi sokuphendula esikwazi ukusekelaukulungiswa kwamandla kwemizuzwana emi-2
Ngokunikeza impendulo enembile yamandla egridi, i-PC321 ivumela uhlelo lokulawula ukulawula ukuphuma kwe-PV ngokunembile—ukuvimbela ukugeleza kwamandla okuphambene ngaphandle kokunciphisa ngokungadingekile ukukhiqizwa kwelanga.
Okubalulekile, i-PC321 ayizilawuli i-inverter ngokwayo. Kunalokho, iyazilawula.kwenza ukulawula okuthembekile ngokunikeza idatha yokulinganisa encike kuzo zonke izinqumo zezinga eliphezulu.
Kungani Ukuthunyelwa Kwe-Zero Okungaguquki Ngokuvamile Kuhluleka Emakhaya Angempela
Ezindaweni zokuhlala zangempela, izinguquko zomthwalo azibikezeleki:
-
Izinto zikagesi ziyavuleka futhi zivaliwe
-
Amashaja e-EV aqala ngokuzumayo
-
Amaphampu okushisa kanye nomjikelezo wezinhlelo ze-HVAC
Izilungiselelo ze-zero-export ezisekelwe ku-inverter ezimile azikwazi ukuphendula ngokushesha ngokwanele kulezi zenzakalo. Umphumela uba yilokhu okulandelayo:
-
Ukuthunyelwa kwegridi yesikhashana
-
Ukunciphisa i-PV ngokweqile
Ukulawula okunamandla, okusekelwe kumitha kunikeza ikhambi elizinzile nelisebenza kahle.
Izinto Okucatshangelwayo Ngokusetshenziswa Kwezinhlelo Zokulwa Nokuhlanekezela Kwezindawo Zokuhlala
Uma uklama uhlelo lokugeleza kwamandla olunamandla oluphikisana nokubuyela emuva, cabanga ngalokhu:
-
Indawo yokufaka imitha e-PCC
-
Ukuthembeka kokuxhumana phakathi kwamadivayisi
-
Isikhathi sokuphendula se-loop yokulawula
-
Ukuhambisana namapulatifomu e-inverter noma e-EMS
Ukwakheka okuklanywe kahle kuqinisekisa ukuhambisana ngaphandle kokulahla ukusetshenziswa kwamandla.
Isiphetho: Ukwakhiwa Kwezakhiwo Kubaluleke Kakhulu Kunokuba Amadivayisi Ngamunye
Ukulawula ukugeleza kwamandla okulwa nokubuyela emuvaakufezwa ngokuvimbela ukukhiqizwa kwelanga. Kungumphumela we-ukwakheka kwesistimu okuhlelwe kahlelapho ukulinganisa, ukuxhumana, kanye nokulawula kusebenza ndawonye ngesikhathi sangempela.
Njengoba izinhlelo ze-PV zokuhlala ziba namandla kakhulu,amamitha wamandla ahlakaniphile esibonakalayo segridi abe yingxenye eyisisekeloamasu okugeleza kwamandla asebenzayo okulwa nokuphenduka.
Kumaphrojekthi elanga ezindlu adinga ukulawulwa okuqondile kokuthunyelwa kwamanye amazwe, ukuqonda ukwakheka kwesistimu kuyisinyathelo sokuqala sokufakwa okuzinzile nokuhambisanayo.
