Ungawaklama Kanjani Amandla Angcono Kakhulu Wesipele Sebhethri Wasekhaya?

Ngokuthuthukiswa kobuchwepheshe obusha bamandla kanye nezinkinga zemvelo ezandayo emhlabeni wonke, ukwandisa ukusetshenziswa kwamandla ahlanzekile njengamandla elanga namandla omoya kuba enye yezindikimba zesikhathi sethu. Kulesi sihloko, sizogxila ezindleleni zokusebenzisa amandla elanga futhi sikwethule indlela yokuklama okuhle kakhulu ngokwesayensiamandla okulondoloza ibhethri ekhaya. Imibono Eyiphutha Evamile Lapho Uklama Uhlelo Lokugcina Amandla Wasekhaya 1. Gxila kuphela kumthamo webhethri 2. Ukumiswa kwesilinganiso se-kW/kWh kuzo zonke izinhlelo zokusebenza (akukho isilinganiso esinqunyiwe sazo zonke izimo) Ukuze kuzuzwe umgomo wokwehlisa izindleko ezimaphakathi zikagesi (i-LCOE) kanye nokwandisa ukusetshenziswa kwesistimu, izingxenye ezimbili ezibalulekile zidinga ukucatshangelwa lapho kwakhiwa uhlelo lokugcina amandla ekhaya lwezinhlelo zokusebenza ezahlukene: uhlelo lwe-PV kanyeuhlelo lokusekela ibhethri lasekhaya. UKUKHETHWA OKUNEMBILE KOHLELO LE-PV KANYE NOHLELO LWESIPELE NGEBHATHI EKHAYA KUDINGA UKUNAKEKELA AMAPHUZU ALANDELAYO. 1. I-Solar Radiation Level Ukuqina kokukhanya kwelanga kunomthelela omkhulu ekukhetheni uhlelo lwe-PV. Futhi ngokombono wokusetshenziswa kwamandla, amandla okukhiqiza amandla ohlelo lwe-PV kufanele anele ukumboza ukusetshenziswa kwamandla kwansuku zonke kwasendlini. Imininingwane ehlobene nokushuba kokukhanya kwelanga endaweni ingatholwa nge-inthanethi. 2. Ukusebenza Kwesistimu Ngokuvamile, uhlelo oluphelele lokugcina amandla e-PV lulahlekelwa amandla cishe ngo-12%, okuhlanganisa ikakhulukazi ● Ukulahlekelwa kokusebenza kahle kokuguqulwa kwe-DC/DC ● Ukulahlekelwa ukusebenza kahle komjikelezo wokushajwa kwebhethri/wokukhipha ● Ukulahlekelwa kokusebenza kahle kokuguqulwa kwe-DC/AC ● Ukulahleka kokushaja kwe-AC Kukhona nokulahlekelwa okuhlukahlukene okungenakugwenywa ngesikhathi sokusebenza kwesistimu, njengokulahlekelwa kokudlulisela, ukulahlekelwa kolayini, ukulahlekelwa kokulawula, njll. Ngakho-ke, lapho siklama isistimu yokugcina amandla e-PV, kufanele siqinisekise ukuthi amandla ebhethri aklanyelwe angahlangabezana nesidingo sangempela njengoba kakhulu ngangokunokwenzeka. Uma kucatshangelwa ukulahleka kwamandla esistimu iyonke, umthamo wangempela webhethri odingekayo kufanele ube Amandla ebhethri adingekayo = umthamo webhethri oklanyelwe / ukusebenza kahle kohlelo 3. Isistimu Yesipele Sebhethri Lasekhaya Ikhono Elitholakalayo “Amandla ebhethri” kanye “nomthamo otholakalayo” kuthebula lepharamitha yebhethri yizinkomba ezibalulekile zokuklama isistimu yokugcina amandla ekhaya. Uma umthamo okhona ungakhonjiswa kumapharamitha webhethri, ungabalwa ngomkhiqizo wokujula kwebhethri lokuphuma (DOD) kanye nomthamo webhethri.

Uma usebenzisa ibhange lebhethri ye-lithium ene-inverter yokugcina amandla, kubalulekile ukunaka ukujula kokukhishwa ngaphezu komthamo otholakalayo, ngoba ukujula okusethiwe kokukhishwa kungase kungafani nokujula kokukhishwa kwebhethri ngokwayo. uma isetshenziswa ne-inverter ethile yokugcina amandla. 4. Ukufaniswa kwepharamitha Lapho uklama auhlelo lokugcina amandla ekhaya, kubaluleke kakhulu ukuthi imingcele efanayo ye-inverter ne-lithium battery bank ifaniswe. Uma amapharamitha engafani, isistimu izolandela inani elincane ukuze isebenze. Ikakhulukazi kumodi yamandla elindile, umklami kufanele abale ukushajwa kwebhethri nezinga lokuphuma kanye namandla okuphakela amandla ngokusekelwe kunani eliphansi. Isibonelo, uma i-inverter eboniswe ngezansi ifaniswe nebhethri, inani eliphezulu lokushaja/lokukhipha amandla esistimu lizoba ngu-50A.

5. Izimo Zokusebenza Izimo zohlelo lokusebenza nazo ziwukucatshangelwa okubalulekile lapho uklama isistimu yokugcina amandla ekhaya. Ezimweni eziningi, indawo yokugcina amandla ingasetshenziselwa ukukhulisa izinga lokusebenzisa amandla amasha kanye nokunciphisa inani likagesi elithengwe igridi, noma ukugcina ugesi okhiqizwa yi-PV njengohlelo lokulondoloza ibhethri lasekhaya. Isikhathi Sokusetshenziswa Amandla okulondoloza ibhethri ekhaya Ukuzakhela kanye nokuzidla Isimo ngasinye sinomqondo wokuklama ohlukile. Kodwa yonke i-logic ye-design nayo isekelwe esimweni esithile sokusebenzisa ugesi wasekhaya. Inkokhelo Yesikhathi Sokusebenzisa Uma inhloso yamandla ebhethri ayisipele ekhaya kuwukumboza isidingo somthwalo ngezikhathi eziphakeme kakhulu ukugwema amanani aphezulu kagesi, amaphuzu alandelayo kufanele aqashelwe. A. Isu lokwabelana kwesikhathi (iziqongo nezigodi zamanani kagesi) B. Ukusetshenziswa kwamandla ngesikhathi samahora aphakeme (kWh) C. Isamba sokusetshenziswa kwamandla kwansuku zonke (kW) Ngokufanelekile, umthamo otholakalayo webhethri ye-lithium yasekhaya kufanele ube phezulu kunesidingo samandla (kWh) phakathi namahora aphakeme. Futhi umthamo wokuphakelwa kwamandla wesistimu kufanele ube phezulu kunomthamo wamandla osetshenziswa nsuku zonke (kW). Amandla Ayisipele Sebhethri Ekhaya Esimeni sesistimu yokusekela ibhethri yasekhaya, iikhaya lithium ibhethriikhokhiswa uhlelo lwe-PV kanye negridi, futhi ikhishelwa ukuhlangabezana nesidingo somthwalo phakathi nokucisha kwegridi. Ukuze kuqinisekiswe ukuthi ukuphakelwa kukagesi ngeke kuphazamiseke ngesikhathi sokucisha kukagesi, kuyadingeka ukuthi kuklanywe uhlelo olufanele lokugcina amandla ngokulinganisa isikhathi sokunqamuka kukagesi kusenesikhathi kanye nokuqonda inani eliphelele likagesi osetshenziswa imizi, ikakhulukazi isidingo sikagesi. imithwalo yamandla aphezulu. Ukuzakhela kanye nokuzidla Lesi simo sohlelo lokusebenza sihlose ukuthuthukisa izinga lokuzikhiqiza kanye nokuzisebenzisela uhlelo lwe-PV: lapho uhlelo lwe-PV lukhiqiza amandla anele, amandla akhiqizwayo azonikezwa umthwalo kuqala, futhi okweqile kuzogcinwa ebhethrini ukuze kuhlangatshezwane nayo. isidingo somthwalo ngokukhipha ibhethri lapho isistimu ye-PV ikhiqiza amandla anganele. Lapho uklama uhlelo lokugcina amandla ekhaya ngale njongo, inani eliphelele likagesi elisetshenziswa yikhaya usuku ngalunye liyabhekwa ukuze kuqinisekiswe ukuthi inani likagesi okhiqizwa yi-PV lingahlangabezana nesidingo sikagesi. Idizayini yezinhlelo zokugcina amandla e-PV ngokuvamile idinga ukucatshangelwa kwezimo zohlelo lokusebenza eziningi ukuze kuhlangatshezwane nezidingo zikagesi wasekhaya ngaphansi kwezimo ezihlukene. Uma ufuna ukuhlola izingxenye ezinemininingwane eyengeziwe zomklamo wesistimu, udinga ochwepheshe bezobuchwepheshe noma izifaki zesistimu ukuze unikeze ukwesekwa kobuchwepheshe okwengeziwe. Ngesikhathi esifanayo, umnotho wezinhlelo zokugcina amandla ekhaya nawo uyinkinga ebalulekile. Uyithola kanjani imbuyiselo ephezulu ekutshalweni kwezimali (i-ROI) noma ukuthi kukhona ukwesekwa okufanayo kwenqubomgomo yoxhaso, kube nomthelela omkhulu ekukhetheni kwedizayini yesistimu yokugcina amandla ye-PV. Okokugcina, uma kucatshangelwa ukukhula okungenzeka esikhathini esizayo kwesidingo sikagesi kanye nemiphumela yokuncipha kwamandla asebenzayo ngenxa yokubola kwezingxenyekazi zekhompiyutha, sincoma ukukhulisa umthamo wesistimu lapho siklama.amandla okusekela ibhethri ezixazululo zasekhaya.
