Ubushakashatsi bushya bwakozwe n’Ubudage bwa Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) bwerekanye ko guhuza sisitemu yo hejuru ya PV hamwe n’ububiko bwa batiri hamwe na pompe y’ubushyuhe bishobora kuzamura imikorere ya pompe mu gihe bigabanya gushingira ku mashanyarazi ya gride.
Abashakashatsi ba Fraunhofer ISE bakoze ubushakashatsi ku buryo sisitemu yo guturamo yo hejuru ya PV ishobora guhuzwa na pompe yubushyuhe hamwe nububiko bwa batiri.
Basuzumye imikorere ya sisitemu ya PV-ubushyuhe bwa pompe-batiri ishingiye kuri smart-grid (SG) igenzura ryiteguye mu nzu yumuryango umwe yubatswe mu 1960 i Freiburg, mu Budage.
Umushakashatsi Shubham Baraskar yatangarije ikinyamakuru pv ati: "Byagaragaye ko kugenzura ubwenge byongereye ingufu za pompe mu kongera ubushyuhe bwashyizweho." “Igenzura rya SG-Ready ryongereye ubushyuhe bwo gutanga ku 4.1 Kelvin mu gutegura amazi ashyushye, hanyuma bigabanya ibihe by’ibihe (SPF) ku kigero cya 5.7% kuva kuri 3.5 bigera kuri 3.3. Byongeye kandi, ku buryo bwo gushyushya ikirere uburyo bwo kugenzura ubwenge bwagabanije SPF ku gipimo cya 4% kuva kuri 5.0 igera kuri 4.8. ”
SPF nigiciro gisa na coefficient yimikorere (COP), hamwe nikinyuranyo kibarwa mugihe kirekire hamwe nimbibi zitandukanye.
Baraskar na bagenzi be basobanuye ibyo babonye muri “Isesengura ryimikorere nigikorwa cya Photovoltaic-bateri yubushyuhe bwa pompe ishingiye kumibare yo gupima umurima, ”Iherutse gusohoka muriImirasire y'izuba.Bavuze ko inyungu nyamukuru ya sisitemu ya pompe yubushyuhe igizwe no kugabanya imikoreshereze ya gride no kugabanya amashanyarazi.
Sisitemu ya pompe yubushyuhe ni 13.9 kW-yubutaka-butanga ubushyuhe bwateguwe hamwe nububiko bwo kubika ubushyuhe. Yishingikiriza kandi ku kigega kibikwa hamwe n’amazi meza yo kubyara amazi ashyushye yo mu ngo (DHW). Ibice byombi byabitswe bifite ibyuma bifasha amashanyarazi.
Sisitemu ya PV yerekeza mu majyepfo kandi ifite inguni ya dogere 30. Ifite ingufu ouput ya 12.3 kW hamwe na module ya metero kare 60. Batare ihujwe na DC kandi ifite ubushobozi bwa 11.7 kWt. Inzu yatoranijwe ifite ahantu hashyushye ho kuba 256 m2 hamwe nubushyuhe buri mwaka bwa 84.3 kWt / m²a.
Abashakashatsi basobanuye bati: "Imbaraga za DC ziva muri PV na batiri zihindurwamo AC binyuze muri inverter ifite ingufu nini za AC zingana na 12 kW hamwe n’uburayi bukora 95%", abashakashatsi basobanuye ko igenzura rya SG rishobora gukorana na umuyoboro w'amashanyarazi no guhindura imikorere ya sisitemu. Ati: "Mu gihe cy'imitwaro myinshi ya gride, umuyobozi wa gride arashobora guhagarika imikorere ya pompe yubushyuhe kugirango agabanye imiyoboro ya gride cyangwa ashobora no gufungura ku gahato mu rubanza rutandukanye."
Muburyo buteganijwe bwa sisitemu, ingufu za PV zigomba kubanza gukoreshwa mumitwaro yinzu, hamwe nibisigaye bitangwa muri bateri. Imbaraga zirenze zishobora koherezwa muri gride gusa, niba nta mashanyarazi asabwa murugo kandi bateri yarishye rwose. Niba sisitemu ya PV na bateri byombi bidashobora guhaza ingufu inzu ikenera, umuyoboro w'amashanyarazi urashobora gukoreshwa.
Abashakashatsi bagize bati: "Uburyo bwa SG-Ready bukora iyo bateri yuzuye cyangwa ikarishye ku mbaraga zayo zose kandi haracyari amafaranga asagutse ya PV arahari". Ati: “Ku rundi ruhande, imiterere-karemano yujujwe iyo ingufu za PV ako kanya zikomeje kuba munsi y’inyubako zose zisabwa byibuze mu minota 10.”
Isesengura ryabo ryasuzumye urwego rwo kwikoresha, igice cyizuba, gukora pompe yubushyuhe, ningaruka za sisitemu ya PV na batiri kumikorere ya pompe yubushyuhe. Bakoresheje ibisubizo bihanitse byiminota 1 kuva Mutarama kugeza Ukuboza 2022 basanga igenzura rya SG-Ready ryongereye ubushyuhe bwo gutanga pompe yubushyuhe bwa 4.1 K kuri DHW. Banagaragaje kandi ko sisitemu yageze ku kwikoresha muri rusange 42.9% mu mwaka, ibyo bikaba bisobanura inyungu z’amafaranga kuri banyiri amazu.
Itsinda ry’ubushakashatsi ryasobanuye riti: "Amashanyarazi akenerwa [pompe yubushyuhe] yashyizwe kuri 36% na sisitemu ya PV / bateri, binyuze muri 51% mu buryo bw’amazi ashyushye yo mu ngo na 28% mu buryo bwo gushyushya ikirere", yongeraho ko ubushyuhe bwo hejuru bw’amazi bwagabanutse. ubushyuhe bwa pompe ikora 5.7% muburyo bwa DHW na 4.0% muburyo bwo gushyushya ikirere.
Baraskar yagize ati: "Mu gushyushya ikirere, habonetse n'ingaruka mbi zo kugenzura ubwenge." “Bitewe na SG-Yiteguye kugenzura pompe yubushyuhe ikorera mu gushyushya ikirere hejuru yubushyuhe bwashyizweho. Ibi byatewe nuko igenzura rishobora kongera ubushyuhe bwashyizweho kandi rigakoresha pompe yubushyuhe nubwo ubushyuhe butari bukenewe kugirango ubushyuhe bwumwanya. Twakagombye gutekereza kandi ko ubushyuhe bukabije bwo kubika bushobora gutuma ubushyuhe bwinshi butakaza. ”
Aba bahanga bavuze ko bazakora iperereza ryiyongera rya PV / ubushyuhe bwa pompe hamwe na sisitemu zitandukanye no kugenzura ibitekerezo biri imbere.
Bashoje bati: "Tugomba kumenya ko ibyavuye mu bushakashatsi byihariye kuri sisitemu yasuzumwe ku giti cye kandi birashobora gutandukana cyane bitewe n'inyubako ndetse na sisitemu y'ingufu".
