Tsvagiridzo nyowani kubva kuGerman yeFraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) yakaratidza kuti kusanganisa pamusoro pedenga rePV masisitimu nekuchengetedza bhatiri nemapombi ekupisa kunogona kuvandudza kushanda kwepombi yekupisa uku uchideredza kuvimba nemagetsi egidhi.
Fraunhofer ISE vaongorori vakadzidza kuti masystem ekugara padenga rePV anogona kusanganiswa sei nemapombi ekupisa uye kuchengetedza bhatiri.
Vakaongorora kushanda kwePV-heat pump-battery system yakabva pane smart-grid (SG) yakagadzirira kutonga muimba imwe chete yemhuri yakavakwa muna 1960 muFreiburg, Germany.
"Zvakaonekwa kuti kutonga kwakanaka kwakawedzera kupisa kwepombi nekusimudzira tembiricha," muongorori Shubham Baraskar akaudza pv magazine. “Kudzora kweSG-Ready kwakawedzera tembiricha yekupihwa ne4.1 Kelvin yekugadzirira mvura inopisa, izvo zvakazodzikisa mwaka wekuita factor (SPF) ne5.7% kubva pa3.5 kuenda pa3.3. Uyezve, yenzvimbo yekudziya modhi iyo smart control yakadzikisa SPF ne4% kubva pa5.0 kusvika 4.8.
Iyo SPF kukosha kwakafanana neiyo coefficient of performance (COP), nemusiyano unoverengerwa kwenguva yakareba nemamiriro emuganhu akasiyana.
Baraskar nevamwe vake vakatsanangura zvavakawana mu “Kuongororwa kwekuita uye kushanda kwe photovoltaic-battery heat pump system inobva pane data yekuyera munda,” iyo ichangobva kubudiswa munaSolar Energy Advans.Vati mukana mukuru wePV-heat pombi masisitimu ane yavo yakaderedzwa mashandisirwo egidhi uye yakaderera mutengo wemagetsi.
Iyo yekupisa pombi system ndeye 13.9 kW pasi-chinobva kupisa pombi yakagadzirwa nebuffer yekuchengetedza yekudziya nzvimbo. Inovimba zvakare netangi rekuchengetera uye chiteshi chemvura yakachena kugadzira mvura inopisa yemumba (DHW). Ese maviri matura ekuchengetera akashongedzerwa nemagetsi anobatsira hita.
Iyo PV system yakananga kumaodzanyemba uye ine tilt angle yemadhigirii makumi matatu. Iine simba rekubuda kwe12.3 kW uye module nzvimbo ye60 square metres. Bhatiri ndeye DC-yakabatana uye ine simba re 11.7 kWh. Imba yakasarudzwa ine nzvimbo inodziya yekugara ye256 m2 uye yegore yekudziya kudiwa kwe84.3 kWh/m²a.
"Simba reDC kubva kuPV uye mabhatiri mayuniti anoshandurwa kuita AC kuburikidza neinverter ine yakanyanya AC simba re12 kW uye kugona kweEurope kwe95%," vaongorori vakatsanangura, vachiona kuti SG-yakagadzirira kutonga inokwanisa kudyidzana nayo. iyo grid yemagetsi uye gadzirisa mashandiro ehurongwa zvinoenderana. "Mukati menguva yekuremerwa kwegidhi, mushandisi wegidhi anogona kudzima pombi yekupisa kuti aderedze kunetsa kwegidhi kana kuti anogonawo kuvharirwa mune imwe nyaya."
Pasi peyakarongwa sisitimu yekumisikidzwa, simba rePV rinofanirwa kutanga kushandiswa kumitoro yemba, nekuwedzera kuri kupihwa kubhatiri. Simba rakawandisa rinogona kutumirwa kunze kune grid, kana pasina magetsi anodiwa neimba uye bhatiri rakazara. Kana zvese zviri zviviri PV system nebhatiri zvisingakwanisi kuvhara simba reimba, gidhi remagetsi rinogona kushandiswa.
"Iyo SG-Ready modhi inovhurwa kana bhatiri razara kana kuti richichaja nesimba raro guru uye pachine PV yakawandisa iripo," vadzidzi vakadaro. "Kune rumwe rutivi, mamiriro ekutanga anozadzikiswa apo simba rePV rinoramba rakaderera pane yakazara chivakwa chinodiwa kwemaminetsi gumi."
Ongororo yavo yakafunga kuzvidyira mazinga, chikamu chezuva, kupisa kwepombi kushanda zvakanaka, uye kukanganiswa kwePV system uye bhatiri pane kupisa kwepombi kushanda zvakanaka. Vakashandisa yakakwirira-resolution 1-miniti data kubva muna Ndira kusvika Zvita 2022 uye vakawana kuti SG-Ready control yakawedzera kupisa kwepombi yekupisa tembiricha ne4.1 K yeDHW. Vakaona zvakare kuti sisitimu yakawana kuzvidyira kwese kwe42.9% mukati megore, izvo zvinoshandura mukubatsira mari kune varidzi vedzimba.
"Kudiwa kwemagetsi kwe [pombi yekupisa] kwakafukidzwa ne36% nePV / bhatiri system, kuburikidza ne51% mumvura inopisa yemumba uye 28% munzvimbo yekupisa," boka rekutsvaga rakatsanangura, richiwedzera kuti tembiricha yepamusoro yekunyura yakaderedzwa. kupisa kwepombi kushanda zvakanaka ne5.7% muDHW mode uye ne4.0% munzvimbo yekudziya modhi.
"Nekuda kwekupisa kwenzvimbo, kukanganisa kwehungwaru kutonga kwakawanikwa," akadaro Baraskar. “Nekuda kweSG-Yakagadzirira kudzora pombi yekupisa inoshanda munzvimbo yekudziya pamusoro petembiricha yekupisa. Izvi zvaikonzerwa nekuti kudzora pamwe kwakawedzera tembiricha yekuchengetera uye yakashanda pombi yekupisa kunyangwe kupisa kwaisadikanwa pakudziya kwenzvimbo. Zvinofanirawo kutariswa kuti tembiricha yakawandisa yekuchengetedza inogona kukonzeresa kurasikirwa kwekupisa kwekuchengetedza. "
Masayendisiti akati achaongorora mamwe maPV / kupisa pombi musanganiswa nehurongwa hwakasiyana uye kudzora pfungwa mune ramangwana.
"Izvo zvinofanirwa kucherechedzwa kuti izvi zvakawanikwa zvakanangana neayo akaongororwa masisitimu uye anogona kusiyana zvakanyanya zvichienderana nekuvaka uye simba system yakatarwa," vakapedzisa.
