Njengoba amanani kagesi ekhuphuka kanye nomfutho wokusimama ukhula ngamandla, ihhotela e-Czech Republic lalibhekene nezinselele ezimbili ezinkulu: ukukhuphuka kwezindleko zikagesi namandla angathembekile avela kugridi. Iphendukela ku-RENAC Energy ukuze ithole usizo, ihhotela lamukele ikhambi langokwezifiso le-Solar+Isitoreji manje esinika amandla ukusebenza kwalo ngendlela ephumelela kakhulu nangokuzinzile. Isixazululo? Amasistimu amabili we-RENA1000 C&I All-in-one Energy Storage abhangqwe namaKhabhinethi amabili e-STS100.
Amandla Athembekile Ehhotela Elimatasatasa
*Amandla esistimu: 100kW/208kWh
Ukuba seduze kwaleli hhotela efekthri i-Škoda kulibeka endaweni yamandla adingeka kakhulu. Imithwalo ebalulekile ehhotela njengeziqandisi nokukhanya okubalulekile kuncike ekunikezeni amandla okuzinzile. Ukuze kulawuleke ukukhuphuka kwezindleko zamandla kanye nokunciphisa izingozi zokunqamuka kukagesi, ihhotela litshale imali ezinhlelweni ezimbili ze-RENA1000 namakhabethe amabili e-STS100, lakha isisombululo sokugcina amandla esingu-100kW/208kWh esisekela igridi ngenye indlela ethembekile, neluhlaza.
I-Smart Solar+Isitoreji Sekusasa Elisimeme
Okugqamile kwalokhu kufakwa yi-RENA1000 C&I All-in-one Hybrid ESS. Akukhona nje kuphela mayelana nokugcinwa kwamandla—kuyigridi encane ehlakaniphile ehlanganisa kalula amandla elanga, ukugcinwa kwebhethri, ukuxhumeka kwegridi, nokuphatha okuhlakaniphile. Ifakwe inverter eyi-hybrid engu-50kW kanye nekhabhinethi yebhethri engu-104.4kWh, isistimu ingakwazi ukumelana nokufika ku-75kW okokufaka kwelanga ne-DC enamandla kagesi angu-1000Vdc. Ihlanganisa ama-MPPT amathathu kanye nokokufaka kwezintambo eziyisithupha ze-PV, i-MPPT ngayinye eklanyelwe ukuphatha kufika ku-36A wamanje futhi imelane namaza omjikelezo omfushane afika ku-40A—ukuqinisekisa ukubanjwa kwamandla okuphumelelayo.
*Umdwebo wesistimu we-RENA1000
Ngosizo lweKhabhinethi ye-STS, lapho igridi ihluleka, isistimu ingashintsha ngokuzenzakalelayo kumodi ye-off-grid ngaphansi kuka-20ms, igcine yonke into isebenza ngaphandle kokuphazanyiswa. Ikhabhinethi ye-STS ihlanganisa imojula engu-100kW STS, i-100kVA isolation transformer, nesilawuli segridi encane, kanye nengxenye yokusabalalisa amandla, ukulawula kalula ukushintsha phakathi kwegridi namandla agciniwe. Ukuze uthole ukuguquguquka okwengeziwe, isistimu ingaphinda ixhume kujeneretha kadizili, inikeze umthombo wamandla oyisipele uma kudingeka.
*Umdwebo wesistimu we-STS100
Okwenza i-RENA1000 ihluke i-Smart EMS yayo eyakhelwe ngaphakathi (Uhlelo Lokuphathwa Kwamandla). Lolu hlelo lusekela izindlela zokusebenza eziningi, okuhlanganisa imodi yesikhathi, imodi yokuzisebenzisela wena, ukunwetshwa okuguquguqukayo kwemodi yesiguquli, imodi yokwenza ikhophi yasenqolobaneni, ukuthekelisa okuyiziro, nokulawulwa kokufunwa. Ukuthi isistimu isebenza kugridi noma i-off-grid, i-Smart EMS iqinisekisa uguquko olungenazihibe nokusebenzisa amandla afanele.
Ukwengeza, inkundla yokuqapha ehlakaniphile ye-RENAC yakhelwe amasistimu ahlukahlukene wamandla, okuhlanganisa amasistimu e-PV akugridi, amasistimu okugcina amandla okuhlala, amasistimu okugcina amandla e-C&I kanye neziteshi zokushaja ze-EV. Ihlinzeka ngokuqapha nokuphatha ngesikhathi sangempela, ukusebenza okuhlakaniphile nokunakekelwa, kanye nezici ezifana nokubala imali engenayo kanye nokuthunyelwa kwedatha.
Inkundla yokuqapha yale phrojekthi ngesikhathi sangempela inikeza idatha elandelayo:
Isistimu ye-RENA1000 yokugcina amandla ingaphezu nje kokusebenzisa amandla elanga—ivumelana nezidingo zehhotela, iqinisekisa amandla athembekile, angaphazamiseki kuyilapho inciphisa ukuncika emithonjeni yamandla evamile.
Ukonga Kwezezimali kanye Nomphumela Wemvelo Kokukodwa
Lolu hlelo lwenza okungaphezu nje kokugcina amandla evuliwe—liphinde longe imali yehhotela futhi lisize imvelo. Ngokulondolozwa okulinganiselwe konyaka okungu-€12,101 ezindlekweni zamandla, ihhotela lisethubeni lokubuyisela utshalomali lwalo ngeminyaka emithathu nje. Ngasohlangothini lwezemvelo, ukukhishwa kwe-SO₂ kanye ne-CO₂ okunqanyulwa yisistimu kulingana nokutshala amakhulu ezihlahla.
Isixazululo sesitoreji samandla se-RENAC se-C&I nge-RENA1000 sisize leli hhotela ukuthi lithathe isinyathelo esikhulu esibheke ekuzimeleni kwamandla. Kuyisibonelo esicacile sendlela amabhizinisi anganciphisa ngayo i-carbon footprint, onge imali, futhi ahlale elungiselele ikusasa—konke kuyilapho egcina imisebenzi isebenza kahle. Emhlabeni wanamuhla, lapho ukusimama nokonga kuhambisana, izisombululo ze-RENAC zinikeza amabhizinisi ipulani lempumelelo.
