Chifukwa cha kukwera kwa mitengo yamagetsi komanso kukwera kwamphamvu kwamphamvu, hotelo ina ku Czech Republic inali kukumana ndi zovuta ziwiri zazikulu: kukwera mtengo kwa magetsi ndi mphamvu yosadalirika yochokera ku gridi. Potembenukira ku RENAC Energy kuti athandizidwe, hoteloyo idatengera njira yachizolowezi ya Solar+Storage yomwe tsopano ikuyendetsa ntchito zake moyenera komanso mokhazikika. Njira yothetsera vutoli? Awiri a RENA1000 C&I All-in-one Energy Storage Systems ophatikizidwa ndi makabati awiri a STS100.
Mphamvu Zodalirika Pahotelo Yotanganidwa
* Mphamvu Yadongosolo: 100kW/208kWh
Hoteloyi ili pafupi ndi fakitale ya Škoda imayiyika pamalo ofunikira kwambiri mphamvu. Katundu wofunikira mu hotelo monga zoziziritsa kukhosi ndi kuyatsa kofunikira kumadalira magetsi okhazikika. Pofuna kuthana ndi kukwera mtengo wamagetsi ndikuchepetsa kuopsa kwa kuzimitsidwa kwa magetsi, hoteloyo idayika ndalama mu makina awiri a RENA1000 ndi makabati awiri a STS100, ndikupanga njira yosungira mphamvu ya 100kW/208kWh yomwe imathandizira gululi ndi njira yodalirika, yobiriwira.
Smart Solar+Storage ya Tsogolo Lokhazikika
Chosangalatsa kwambiri pakukhazikitsa uku ndi RENA1000 C&I All-in-one Hybrid ESS. Sizokhudza kusungirako mphamvu zokha, ndi makina opangira ma microgrid omwe amaphatikiza mphamvu ya dzuwa, kusungirako batire, kulumikizana ndi gridi, komanso kasamalidwe kanzeru. Yokhala ndi inverter yosakanizidwa ya 50kW ndi kabati ya batire ya 104.4kWh, makinawa amatha kupirira mpaka 75kW yamagetsi adzuwa ndi mphamvu yayikulu ya DC ya 1000Vdc. Imakhala ndi ma MPPT atatu ndi zolowetsa zingwe zisanu ndi chimodzi za PV, MPPT iliyonse yopangidwa kuti izitha kuyendetsa mpaka 36A yapano komanso kupirira mafunde afupipafupi mpaka 40A-kuwonetsetsa kugwidwa kwamphamvu kwamphamvu.
* Chithunzi chadongosolo la RENA1000
Mothandizidwa ndi Bungwe la STS Cabinet, gridi ikalephera, makinawo amatha kusinthiratu ku off-grid mode osakwana 20ms, kusunga chilichonse chikuyenda popanda zovuta. Kabati ya STS imaphatikizapo 100kW STS module, 100kVA isolation transformer, ndi microgrid controller, ndi gawo logawa mphamvu, kuwongolera mosasamala kusintha pakati pa gululi ndi mphamvu zosungidwa. Kuti muthe kusinthasintha, makinawo amathanso kulumikizana ndi jenereta ya dizilo, ndikupereka gwero lamphamvu lothandizira pakafunika.
* Chithunzi cha System cha STS100
Chomwe chimasiyanitsa RENA1000 ndi Smart EMS yake (Energy Management System). Dongosololi limathandizira njira zingapo zogwirira ntchito, kuphatikiza nthawi, njira yodzigwiritsira ntchito, kukulitsa kwamphamvu kwa ma transformer mode, njira zosunga zobwezeretsera, kutumiza zero, ndi kuyang'anira zofuna. Kaya makinawa akugwira ntchito pa gridi kapena kunja kwa gridi, Smart EMS imatsimikizira kusintha kosasinthika komanso kugwiritsa ntchito mphamvu moyenera.
Kuphatikiza apo, nsanja yowunikira mwanzeru ya RENAC idapangidwira makina osiyanasiyana amagetsi, kuphatikiza makina a PV pagridi, makina osungira mphamvu zogona, makina osungira mphamvu a C&I ndi malo opangira ma EV. Imapereka kuyang'anira ndi kuyang'anira nthawi yeniyeni, ntchito yanzeru ndi kukonza, ndi zinthu monga kuwerengera ndalama ndi kutumiza deta.
Pulatifomu yowunikira nthawi yeniyeni ya polojekitiyi imapereka izi:
Dongosolo losungiramo mphamvu la RENA1000 silimangogwiritsa ntchito mphamvu zoyendera dzuwa — limagwirizana ndi zosowa za hoteloyo, kuwonetsetsa kuti pali mphamvu zodalirika, zosasokonezedwa ndikuchepetsa kudalira magwero amagetsi achikhalidwe.
Kusunga Zachuma ndi Zokhudza Zachilengedwe mu Mmodzi
Dongosololi limachita zambiri osati kungoyatsa magetsi, ndikupulumutsanso ndalama za hotelo komanso kuthandiza chilengedwe. Pokhala ndi ndalama zokwana €12,101 pachaka, hoteloyo ili m'njira yoti ibwezenso ndalama zake m'zaka zitatu zokha. Pamaso pa chilengedwe, mpweya wa SO₂ ndi CO₂ wodulidwa ndi dongosololi ndi wofanana ndi kubzala mazana a mitengo.
Njira yosungira mphamvu ya RENAC ya C&I yokhala ndi RENA1000 yathandiza hoteloyi kuchitapo kanthu kuti pakhale ufulu wodziyimira pawokha mphamvu. Ndi chitsanzo chodziwikiratu cha momwe mabizinesi angachepetse kuchuluka kwa mpweya wawo, kusunga ndalama, ndikukhala okonzekera zam'tsogolo - zonse zomwe zikuyenda bwino. M'dziko lamasiku ano, momwe kusungika ndi kusunga ndalama kumayendera limodzi, njira zatsopano za RENAC zimapereka mabizinesi njira yopambana.
