Ngosizo lwezilawuli zezinkampani zangaphandle ezihlakaniphile, isiyondisi sakho somoya singasiza ekunikezeni ibhalansi nokufunwa ngegridi egcwele ilanga.
Nakuba abalawuli bekhathazekile ngomthelela wamandla elanga kumanethiwekhi okusabalalisa ama-voltage aphansi, abathuthukisi bafuna izindlela zokusebenzisa umthwalo wasendlini ukuze banciphise ukucindezeleka.
Ngesonto eledlule, ngixoxe nenkampani ebizwa ngePaladin eNew Zealand.Eminyakeni emine noma emihlanu edlule, ukugxila kwenkampani bekukusilawuli, esidlulisa amandla kagesi engeziwe ukusuka ku-PV kuya ekushiseni kukagesi kwekhasimende.Inkonzo yamanzi.Lesi yisimo sokuwina: ikhasimende lithola amanzi ashibhile ashibhile, futhi i-shunt inikeza umthwalo wokuthola ugesi, ngaphandle kwalokho izobeka ingcindezi kugridi.
Lapho i-AEMO inquma ukuthi i-SA Power Networks idinga amandla ukuze ivale imicimbi “yesidingo samakhasimende” ukuze igweme izehlakalo “zesidingo esibi”, izinto ezintsha ezinjengokushuthwa kwe-solar zazibaluleke kakhulu (yathi lokhu kuphakelwa kukagesi kuzosetshenziswa nje kuyaqabukela).
Njengoba umphathi we-Paladin u-Mark Robinson abonisa, inkampani yamandla kagesi ayifuni ukuphuma phakathi kuka-10 ekuseni no-2 pm ngoba yilapho u-overvoltage kwenzeka-lapho amandla kagesi asendaweni afinyelela ku-257V, ukuhlehla Isiguquli siqala ukuvala.
Ngokuqala kwenhlekelele ye-COVID, lapho umthuthukisi oholayo wePaladin uKen Smith ezibophezele ekunikezeni isilawuli esine-interface engenantambo enenzwa yokushisa yesifudumezi samanzi, waphinde walandela umbono wokuthi isifudumezi-moya singaqeda insizakalo ngamanzi ashisayo - sisebenza njenge ukusetshenziswa endaweni Umthwalo welanga oweqile.
Okungenantambo, uSmith uthe ufuna ukuyigwema iWiFi ngoba idinga abanikazi abaningi.Esikhundleni salokho, waphendukela ezingeni lomsakazo elibizwa nge-LoRa, okuyindinganiso engenantambo yamandla aphansi yebanga elide (lokhu ukufakwa kweWikipedia).
“Ilingana cishe kubhendi yefrikhwensi efanayo nobubanzi obudala bepheyija, kodwa izinga ledatha eliphansi.Uma imikhawulo ye-LORA yeqiwe, ngaphandle kokudela ukusebenza, ngingathumela ukusakazwa kwedatha okufushane okungitshela konke okungabonwa yi-Paladin.
Lokhu kwanelisa umqondo kaSmith wokucabangela ukusetshenziswa kwama-air conditioner.Uthe isikhathi esithile, imishini yesimanje yokupholisa umoya ifake “imishini evumela ukusabela kwesidingo” noma i-DRED.
I-DRED isetshenziswa ngokuhambisana nezidingo zenkampani yamandla, ngakho-ke uma kukhona ukushoda kwamandla (isibonelo, ngesikhathi segagasi lokushisa noma lapho ukunikezwa kwamandla kuphazamiseka), inethiwekhi ingavala noma ivale isimo somoya.
USmith usitshele ukuthi umbono wakhe uphambene nendlela i-intanethi esebenza ngayo-vula noma uvule isiphephetha-moya ukuze ubambe amandla elanga engeziwe ohlelweni lwe-photovoltaic lwasekhaya.
Uthe ekuboneni kokuqala, lokhu kubonakala kuyinkinga enzima kakhulu, ngoba kunezilungiselelo eziningi ezingenzeka zama-compressor air-conditioning anamandla ahlukene.
"Kuthatha ukulala okumbalwa kanye namabhodwe ambalwa ekhofi ukuze uqaphele-ukuba yinkimbinkimbi akubalulekile.Senze ibhokisi elingathola ukusakazwa okuvela [ku-Paladin controller-SolarQuotes ekhona].Vele uyivule futhi ungakwazi ukulawula i-air conditioner.”
Isilawuli se-Paladin “silawula amandla e-compressor ukuze afane nelanga, ukuze ungachithi imali eningi ngesivinini esikhulu.”Kumsebenzisi wokugcina, ama-air conditioner amaningi angasebenzisa amasenti angu-12 (i-kilowatt ngehora) kagesi esikhundleni samasenti angu-30 kagesi.
Futhi, njengokudlulisa amandla elanga engeziwe ezinsizeni zamanzi ashisayo, kuphinde kusize igridi ngoba kunciphisa ukuthunyelwa kwamanye amazwe ngesikhathi samahora aphakeme.
"Futhi ungasebenzisa amayunithi amaningi-uma enye yama-compressor icishiwe, iyunithi yesibili ingaqalwa, njalonjalo."
Wathi kukhona enye inzuzo: ngokufanisa amandla e-air conditioner namandla elanga angaphezu kwamandla, inqubo yokuletha indlu ekushiseni okudingekayo ingase ibe kancane kakhulu kunokuba ingabikho isilawuli, kodwa iyunithi enkulu ifakwe i-compressor ye-4kW. ngeke Zama kanzima ukwehlisa izikweletu zamakhasimende.
Umphathi we-Paladin, u-Mark Robinson, wengeze ngokuthi isilawuli se-Paladin siphendula ngokushesha ngokwanele emthwalweni womndeni wonke-“izosabela njengoba amafu enyakaza”-noma uma othile ebeka iketela, isilawuli sizonciphisa ukungena kwesimo somoya sikagesi.
I-Paladin ithe intuthuko ihamba kahle, futhi uSmith wathi iqoqo lokuqala lamasosha manje selisendaweni yokusebenzela yasePaladin.
URobinson waphawula: “Ngemva kokuhlolwa kokugcina, sithemba ukuyibeka emakethe ngaphambi kukaKhisimusi.”
Uthe isikhathi sibalulekile ngoba eminyakeni embalwa edlule amanani entengo yokudla ayephezulu futhi izindlela zokunciphisa zazingaziwa, ngakho sasingekho ngempela isidingo sokudlulisela amandla emithwalweni yendawo.Kodwa manje njengoba kukhona ama-photovoltais amaningi asekhaya atholakalayo (futhi kuzoba nokunye), isimo sishintshile.
Wathi: "Uma ufuna ukuthumela ngaphandle, kusho ukuthi unephutha."Manje ingxoxo kufanele ibe ukuthi ngingawadla kangakanani amandla ami, ngoba ngiyakwazi ukulawula kangcono.”
URichard Chirgwin (uRichard Chirgwin) uyintatheli enolwazi lweminyaka engaphezu kwengama-30 ehlanganisa izihloko eziningi zobuchwepheshe ezihlanganisa i-electronics, ezokuxhumana, amakhompyutha, nesayensi.
Okuxakayo ukuthi sebezokwethula umkhiqizo omusha obizwa nge- “solar relay” zingakapheli izinsuku ezingama-60, onganika amandla noma yimuphi umthwalo kagesi.
Ama-shunts aguquguqukayo asetshenziselwa imithwalo ephikisanayo.Njengento enkulu yokushisa.Kuye ngenani lamandla elanga angaphezu kwamandla atholakalayo, amandla ahluka kusuka ku-0 kuya ku-2.8 kW.Isibonelo, uma i-1.45 kW yamandla elanga izokhishwa ngezinye izindlela, i-shunt izothumela kuphela u-1.45 kW kuleyo elementi.Kwenziwa njalo ngomzuzwana.
I-solar relay iyiswishi yokuvula/yokucima.Uyayitshela ukuthi idivayisi idla amandla angakanani, futhi uvule idivayisi kuphela uma kukhona okungenani amandla amaningi elanga asele.Isibonelo, uma unephampu yedamu lokubhukuda engu-1.2 kW, izovuleka kuphela uma kukhona okungenani u-1.2 kW wamandla elanga atholakalayo.
Ukuthwebula i-relay yamandla kungaba nzima kakhulu-futhi kungakala ukusetshenziswa kwamandla kwangempela kwedivayisi, futhi kungase kube nokucabanga okuhlakaniphile okungase "kuphushe" idivayisi kusuka kugridi kwezinye izimo.Ngizobathinta ukuze bathole imininingwane.
Ngingabhalisa kuphi?Ebusika, ngenxa yokusebenzisa amandla e-AC, ukusetshenziswa kwami ​​​​kwenyuka, futhi ehlobo, sisebenzisa amandla e-AC ngokucophelela ukuze sandise ukonga izindleko.
Nokho, abantu bahlale bekhathele hhayi njalo.Uma kunendlela yokuqinisekisa ukuthi amandla e-AC asetshenziswa kumandla elanga, ngokuyisisekelo mahhala, lokhu kuyithonya elikhulu lekhaya lami, khona-ke ngizoba yonke indawo.
Uma kuqhathaniswa namanzi ashisayo, ukushintshashintsha kwamandla kuwumthwalo ohlukile, okuwuhlobo lokugcina amandla.Isitoreji sezingxenyekazi zekhompuyutha senza umqondo omkhulu.Akukho okuvulelwe le njongo.
Uma ngingafuni/ngidinga ukuvula ukunikezwa kwamandla e-AC, isibonelo, phakathi nesikhathi esiningi sentwasahlobo, le nkinga yokukhipha amandla elanga aphansi/phezulu ivela, pho kungani uyivula emhlabeni?
Ngisho nendlu enezinga lokushisa elifanele ngokwemvelo phakathi nesikhathi esincane kakhulu sonyaka ngeke isebenzise amandla amaningi ukupholisa/ukushisisa indlu.Yingakho abantu bengasebenzisi kakhulu i-AC kuleyo sizini.
Ngicabange ukuthi ukwengeza umthwalo wezimboni kanye nesitoreji segridi eyengeziwe kungaba yisixazululo esingcono.
Ngivumelana no-Alex, kungani kudingekile ukuvula izinto ezingadingeki.Ngicabanga ukuthi ngeke kusize.Mhlawumbe ijeneretha ingahlelwa ukuba ivale ukuze ilungiswe entwasahlobo lapho isidingo sincipha.
Ngesaba ukuthi lonke lolu lwazi lobuchwepheshe lungaphezu kobuchopho bami obuncane.Kodwa kunezinkinga eziningana.
Ngiyawuqonda umqondo wokukhuphuka kwamandla kagesi aphansi phakathi kuka-10am no-2pm, lokhu kungenxa yokuthi amandla anikezwa kusukela ophahleni lwe-PV kuya kugridi yasendaweni.Kungani bedinga ukuvala amaphaneli e-photovoltaic ophahleni?Akukhona nje ukubuyisela uhlelo emuva kumajeneretha amalahle negesi yemvelo ukuze kuphehlwe ugesi?
Ngaphezu kwalokho, kungakhathaliseki ukuthi iyini imbangela ye-PV eyeqile, uma abantu abaningi bengekho ekhaya, kungani uyisebenzisela ukuvula i-air conditioner noma ukwehlisa izinga lokushisa le-air conditioner.Kubukeka kuwukumosha kimina.(Yebo, ngiyawuqonda umthelela wamanje we-Covid ngokuphathelene nabantu abaningi abavame ukungabikho ekhaya kodwa abafuna ukuba yindawo evamile).
Ngisola ukuthi le mibuzo izogqamisa ukungazi kwami, kodwa kungenzeka ukunikeza umbono omfishane lapho uphendula imibuzo engenhla.
Ngingathanda futhi ukubuza, ingabe kufanele sidlulisele amandla engeziwe kuphakethe lebhethri esikhundleni sokuwasebenzisela ukunika amandla isifudumezi-moya endlini engenalutho?
Yebo, uma kukhona ibhethri elitholakalayo, kunengqondo ukulihambisa lapho, kodwa ngokuvamile abantu abanalo nhlobo ibhethri, noma ngabe banalo ibhethri, bazokhiqiza amandla angaphezu kwamandla ebhethri. .
Ukusebenzisa ama-air conditioner uma kungekho muntu ekhaya kuzonciphisa isidingo sokuthi abantu basebenzise ama-air conditioner uma begoduka ngokuzayo.Kukhona ukulingana phakathi kokumosha amandla okupholisa noma ukushisisa okuvuza kuphela endlini, kanye nesikhathi sokusebenzisa kanye nokuba khona kwamandla.Kuyafaneleka ngempela, kodwa akunjalo ngaso sonke isikhathi.Kuzoncika ezicini eziningi, njengokugqumisa kanye nokuthi abantu baya ekhaya nini.
Ngokupholisa kusengaphambili noma ukushisa ngaphambili, isiyolisi somoya singaphinda sisebenzise amandla amancane jikelele, ngaleyo ndlela sinqobe ukulahlekelwa ukushisa okuzokwenzeka.Lokhu kungenxa yokuthi ukusebenza kahle kwe-air conditioner kuncike emehlukweni phakathi kwezinga lokushisa langaphandle kanye nezinga lokushisa langaphakathi kanye nomsebenzi onzima wokushayela i-air conditioner.Uma ukwazi ukusebenzisa i-air conditioner ngomthwalo ongu-50% ngaphambi nangemuva kokuya ekhaya, ukusetshenziswa kwayo kwamandla kungase kube ngaphansi kunalapho uya ekhaya ngo-100%.Ikakhulukazi ebusika, okunye ukushisisa ngaphambi kokupholisa kwangaphandle kungasebenzisa amandla amancane, bese kuwasebenzisa ngemva kokubuyela ekhaya ngemva kokupholisa.Kodwa-ke, ukuthi idla amandla amaningi noma amancane aphelele kuyinkimbinkimbi kakhulu futhi kuncike kakhulu ezimweni zomuntu ngamunye.
“…Uma abantu abaningi bengekho ekhaya, kungani uyisebenzisela ukuvula i-air conditioner noma ukwehlisa izinga lokushisa le-air conditioner.”
Ekuqaleni ngangicabanga ukuthi kwakunengqondo ukumisa indlu ukuthi ingashisi kuqala ngokusebenzisa isifudumezi-moya phakathi nosuku (usebenzisa amandla elanga futhi ucabange ukuthi ibhethri lasendlini lishajwe ngokugcwele), esikhundleni sokungena endlini efudumele futhi uphendulele umoya. qhubeka.Uma igumbi libanda kakhulu, libanda kakhulu Kulula ukugqoka i-jumper namasokisi kuze kube yilapho indlu iqala ukufudumala.
Ngezinye izikhathi ngithola ukuthi ngemva kosuku olushisayo (noma uchungechunge lwezinsuku ezalandela - isibonelo, izinsuku ezingu-4 ezilandelanayo nezinga lokushisa eliphakeme lama-degrees angu-44), kuyasiza ukugijima i-air conditioner phakathi namahora okungasebenzi ebusuku lapho intengo yegridi ishibhile.Lokhu kusho ukuthi ibhethri lami alikashajwa kakhulu futhi lingaqala ukushajwa ekuseni.Ngokungakhiphi ibhethri ngokujule kakhulu, impilo yebhethri (SLA) inwetshwa ngeminyaka embalwa, okusho ukuthi ngeke ngisadinga ukushintsha ibhethri njalo, ngaleyo ndlela ngisindise isikhathi esiningi.Ibhethri lami lamanje lafakwa ngo-2014 futhi lisakwazi ukuphatha umthwalo owawuphethwe ekuqaleni.Kufanele ngicabange ukuthi ukuphila kweminyaka engu-15 akuyona into elindelekile engenangqondo.
Ukukhuluma ngokupholisa ngaphambi kwesikhathi noma ukushisisa kanye “nokwenza indlu ishise kuqala” kuhle, kodwa lolu hlobo lokungalingani komthwalo wegridi kwenzeka ikakhulukazi enkathini yokushisa epholile entwasahlobo nasekuqaleni kwekwindla, ingasaphathwa eyokubeka umoya.Kushisa noma kupholile.
Ngisho noma i-air conditioner ivuliwe, ngeke idle ugesi omningi, ngoba izindlu eziningi ngalesi sikhathi sonyaka sezivele zisezingeni lokushisa elikhululekile.
Ehlobo, inkinga yokungalingani komthwalo kugridi ayibi kakhulu ngenxa yesidingo esikhulayo se-air conditioning.
Ngokuqondene nokushisa kwangaphambili / ukupholisa emazingeni okushisa aphezulu / aphansi, lokhu kuyisu elibi kakhulu kubantu abaningi ngoba kumosha amandla amaningi futhi kubiza imali eningi.
Ngisanda kukhipha imitha yamanzi ashisayo phakathi namahora okungasebenzi futhi ngaxhuma kabusha amanzi ashisayo kumjikelezo oyinhloko ngokusebenzisa i-circuit breaker kanye nesibali sikhathi sebhethri esiyisipele.Ngibeke isibali sikhathi phakathi kuka-10 ekuseni no-2 ntambama (uma ilanga seliphumile).Ezinyangeni ezifudumele, ngingahle ngikulungise kube ngu-9 ekuseni kuye ku-3 ntambama, kodwa lokhu akudingekile.Ngakho-ke, ngaphandle uma kuguqubele ngempela noma ngingenayo ishawa eshisayo ende (angikaze), cishe njalo ngisebenzisa amandla elanga ukushisa amanzi ashisayo (mahhala!).
Uma uyeka imali engenayo, akukhona “mahhala”.Izindleko zokushisisa amanzi ze-IOW ziyisisekelo sezindleko.Ngaphandle uma ngesizathu esithile unqatshelwe ukuthumela amandla ngaphandle.
Ezingxenyeni eziningi ze-New South Wales, amanani okuphakelayo axhaswa (ngezinye izikhathi aphansi kunamanani kagesi ashisayo angekho phezulu), ngakho-ke kunesikhuthazo esincane noma asikho nhlobo sokushintsha ukushisisa kwamanzi ashisayo kumandla elanga asemini.
Yiqiniso, lapho izimoto zikagesi ziqala ukuba yimithwalo kugridi, futhi ukushajwa kwasekhaya okuhlanganisa i-V2G(H) sekuyinto engokoqobo, zonke lezi zinkinga (okungukuthi, ukugcwala ngokweqile kanye nemikhawulo yokuthumela ngaphandle) zizovele zinyamalale.
Yebo, ngingenile. Ngoba vele sinamandla okudlulisa amanzi ashisayo kithi.imiphumela emihle.angisakwazi ukulinda
Indlela elula yokumunca amandla elanga engeziwe ehlobo ukukhulisa ukusebenza kwezitshalo zokukhipha usawoti emanzini ezikhona kuzo zonke izifundazwe, futhi uzibeke endaweni ephakeme kakhulu phakathi nosuku, futhi uzibuyisele emuva ebusuku.​ futhi udlulisele amanzi engeziwe kumachibi akhona.
Ngo-2007, ngathenga umshini “wamanzi asemoyeni” wokujiya nokuhlanza, opholisa umoya oswakeme futhi ukhiqize amanzi okuphuza, futhi uhlungwe ngezigaba eziningi nokuvala inzalo, okuhlanganisa i-osmosis ehlehlayo (njengezitshalo zokukhipha usawoti emanzini).Ngiphinde ngisebenzise lolu hlelo ukuze ngihlanze amanzi ethangini lokuqoqa amanzi emvula.Okwesithathu, ngezikhathi ezishisayo, ngisebenzisa ama-air conditioner aphathwayo ukuze ngipholise indlu.Lokhu kukhiqiza namanzi, futhi ngiphusha amanzi ku-condenser.“Ezinsukwini libalele” (okungukuthi, libalele futhi linomswakama), ngiyakwazi ukwelapha amalitha angu-8 amanzi.
Ngihamba ngebhayisikili nsuku zonke (ngaphakathi noma ngaphandle) futhi ehlobo ngingaphuza amalitha angu-4-5 amanzi (kuhlanganise nekhofi/itiye).
Ngakho-ke, ngethule izindlela zokulondoloza emazingeni amaningana lapha.Okokuqala, okuhlobene nalokhu ukuthi i-condenser ne-air conditioner iqhutshwa amandla elanga, ngakho-ke ngilondoloza izindleko zokungangenisi kusuka kugridi nokunciphisa i-carbon dioxide.Okwesibili, amandla "adlulele" ngeke angene kugridi, ngaleyo ndlela anciphise "ubunzima" kugridi.Ibhethri izomunca amandla athile, futhi amanzi azomunca amandla engeziwe.Okwesithathu, kwezinye izitolo, ngabona ukuthi ibhodlela le-500ml lamanzi asebhodleleni lithengiswa nge-$1.Uma ngiphuza amalitha angu-4 amanzi kuphela ngosuku, ngingonga imali efinyelela ku-$8 ngosuku uma ngingawathengi ngebhodlela.Ekugcineni, ngokungawathengi amanzi asemabhodleleni, angizange ngiwalahle la mabhodlela alahlwa endaweni yokulahla imfucumfucu, ngaleyo ndlela ngisindise indawo ezungezile.
Sawubona, nginomunye umbuzo.Angazi noma lesi sixazululo singangisiza yini.Ngihlala ku-RV ophahleni.Kunamaphaneli angu-4 x 327W Sunpower ophahleni.Lawa mabhethri alayisha.Ngemva kokuba ibhethri selishajwe ngokugcwele, ngifuna ukuvula i-AC ukuze ngizinzise izinga lokushisa ku-RV, ngakho uma sifika lapho kamuva, asikho isidingo sokwenza yonke into.Ucabanga ukuthi le divayisi izosebenza?Noma ingabe sikhona esinye isixazululo esenziwe ngomumo?Ngiyabonga
Ngizothumela iposi lebhulogi mayelana ne-Catch Power Solar Relay maduze.Le divayisi engu-$250 ingakusiza.Uma i-inverter yakho isebenzisa ukuguqulwa kwama-frequency, i-relay ingabona lapho ibhethri isishajwe ngokugcwele futhi ixhume amandla e-AC ngesixhumi.
Leon, isimo sakho se-RV asifani ncamashi, awuludingi lolu hlobo lwesilawuli, oluqondene ngqo namandla egridi.
Okudingayo i-voltage switch elula ongakwazi ukuqapha i-voltage yebhethri futhi uyisebenzise ukujikeleza i-RV AC.
Ivule ku-voltage ephezulu, bese uyivala nge-volt eyodwa noma ngaphansi.Kuzodingeka usebenzise inani likagesi elithi OFF ngoba lizokwehla ngaphansi komthwalo we-AC-kuya ngosayizi/izimo zebhethri lakho.
Lawula ishaja yebhethri “eshedini”.Ngiqinisa inani le-undervoltage elingaphansi kuka-14V, futhi i-relay ivala noma yikuphi ngaphezu kwaleli nani ukuze ngiqalise ishaja.Ngicabanga ukuthi lapho ibhethri ifinyelela ku-voltage egcwele (14.4), ungasebenzisa indlela efanayo ukunika amandla i-AC.
Lokhu empeleni kuncike ekwehleni kwe-voltage lapho i-compressor iqala.Kusakubiza kuphela cishe u-$5 ukuze uthole!
Landa isahluko sokuqala esithi “Umhlahlandlela Wamandla Elanga Enhle” esibhalwe u-Finn Peacock, umsunguli we-SolarQuotes, mahhala!Uzoqala futhi ukuthola izindaba zamasonto onke ze-SolarQuotes ukuze uhlale unolwazi mayelana nakho konke ukuthuthukiswa kwakamuva emkhakheni welanga lase-Australia.
