Chifukwa chiyani yankho lamagetsi la msasa ndilofunika kwambiri?
Magetsi osasunthika akufunika kumadera akutali a migodi, malo omanga misewu yayikulu komanso malo ochitirako tchuthi.
Pali njira ziwiri zaukadaulo pakali pano: kupanga ma gridi ndi ma jenereta a dizilo ndi ma grid-forming ndi PV-energy-storage systems.
Nkhaniyi ikufanizira njira ziwirizi kuchokera ku miyeso inayi: njira yaukadaulo, zochitika zomwe zimagwiritsidwa ntchito, mtengo ndi kukhazikika.
Kupanga Gridi ndi Jenereta wa Dizilo
Njira Yaukadaulo: Jenereta ya dizilo yokhala ndi malamulo amagetsi a AVR, kugwiritsa ntchito mphamvu zamagetsi.
Zochitika Zoyenera: Makampu osakhalitsa okhala ndi nthawi yomanga yosakwana miyezi isanu ndi umodzi, malo omwe alibe dzuwa lokwanira, kapena mapulojekiti omwe amafunikira mphamvu mwachangu.
Kuwunika Mtengo: Mtengo wochepera wogula (30kW unit: pafupifupi $4,434‑7,390). Mtengo wapachaka wopangira dizilo ndi pafupifupi $65,000 (mafuta a dizilo + kukonza). Kuyendetsa mafuta kumakhala kovuta kumadera akumidzi, zomwe zingapangitse kuti mafuta azisowa.
Kukhazikika: Njira yothetsera dizilo-jenereta: kusinthasintha kwamagetsi ≤ ± 5%, kusinthasintha kwafupipafupi ≤ ± 0.2Hz. Nthawi yoyankha pang'onopang'ono (5-6s), mphamvu yofooka yotha kupirira pakali pano (3-5 nthawi za katundu) poyambitsa injini. Ntchito yoyambira yakuda sikupezeka mphamvu ya gridi itazimitsidwa.
Kupanga Gridi ndi PV-Energy-Storage System
Njira Yaukadaulo: Photovoltaic + lithiamu-iron-phosphate batire + off-grid PV inverter + microgrid energy management system (EMS). Jenereta ya dizilo imagwiritsidwa ntchito ngati gwero la mphamvu zosunga zobwezeretsera.
Zochitika Zoyenera: Makampu anthawi yayitali okhala ndi nthawi yogwira ntchito kupitilira chaka chimodzi, kugwiritsa ntchito mphamvu tsiku lililonse kuposa 300kWh, malo okhala ndi dzuwa lokwanira, kapena mapulojekiti omwe amafunikira kuwunika kwa mpweya wa carbon.
Kuwunika Mtengo: Ndalama zoyambira kwambiri (20kW PV + 167kWh zosungira mphamvu: pafupifupi $52,000-74,000); ntchito pachaka ndalama $35,000. Mtengo wokhazikika wa mphamvu ndi $0.11‑0.16/kWh yokha.
Mukaphatikiza kugwiritsa ntchito dizilo mwadzidzidzi, mtengo wapachaka ndi pafupifupi $6,207, kuyimira kutsika kwamitengo kwa 90.1%. Nthawi yobwezera nthawi zambiri ndi zaka 3-5.
Kukhazikika: Yankho la PV-energy-storage: kusinthasintha kwamagetsi ≤ ± 3%, kusinthasintha kwafupipafupi ≤ ± 0.1Hz; nthawi yosinthira zinthu zambiri ≤10ms. Imapereka kuyankha mwachangu, kuwongolera kwapamwamba komanso mtundu wapamwamba kwambiri wopereka mphamvu.
Zosankha Zosankha
Mtengo wonse pazaka 5 za moyo wonse: pafupifupi. $ 350,000 yothetsera dizilo-jenereta; pafupifupi. $97,000 ya yankho la PV-energy-storage, ndi 74.2% kuchepetsa mtengo wonse posankha PV-energy-storage.
Bajeti yolimba, nthawi yayifupi ya projekiti, kuwala kwadzuwa kosakwanira: Sankhani grid yopangidwa ndi jenereta wa dizilo.
Yesetsani kupulumutsa ndalama kwanthawi yayitali, tsindikani chitetezo cha chilengedwe, kuwala kwadzuwa kokwanira: Sankhani gululi lopangidwa ndi PV-energy-storage.
Yankho mulingo woyenera: Adopt "PV-energy-storage-diesel" micro-grid mode. Mphamvu zoperekedwa ndi PV pamasiku adzuwa, posungira mphamvu pamasiku a mitambo, ndipo jenereta ya dizilo imayatsidwa kokha nyengo yotentha.
Mukufuna njira yopangira magetsi pamisasa?
Xuzhou Zm-Besta imapereka makabati osungiramo zinthu zamtundu wa PV-mphamvu.
Chonde titumizireni kuti mutenge.
