1. Chidule cha Ntchito

This project is located in Ghana, Africa, and serves as a commercial demonstration site integrating solar power generation, battery energy storage, and electric vehicle charging. Designed for EV charging operations, the station has become a regional showcase for clean-energy applications.

Chosinthira chamagetsi chapafupi chili ndi mphamvu yokwanira 120 kVA paChifukwa cha kuchepa kwa mphamvu ya gridi komanso kuzimitsidwa kwa magetsi pafupipafupi, magetsi omwe alipo kale sangathandizire malo onse ochajira magetsi omwe amagwira ntchito ndi mphamvu zonse, zomwe zikuchepetsa kwambiri mphamvu ya gridiyo komanso magwiridwe antchito ake.

Pofuna kuthana ndi vuto la gridi yocheperako komanso magetsi osadalirika, kasitomala adasankha Kabati yosungira mphamvu ya batri ya 125 kW/261 kWh, kuphatikiza ndi Chosinthira chosasinthika cha STS ndi makina oyendera magalimoto a photovoltaic.

Pansi pa mikhalidwe ya gridi yanthawi zonse, makina a dzuwa, makina osungira mabatire, ndi gridi yamagetsi zimagwira ntchito limodzi kuti zithandizire zida zochajira pa mphamvu zonse. Ngati gridi yazima, makinawo amatsiriza kusintha kuchoka pa ntchito yolumikizidwa ndi gridi kupita ku ntchito yopanda gridi mkati mwa sekondi imodzi. Ma charger amphamvu kwambiri a DC amatsekedwa kwakanthawi, pomwe makinawo akupitiliza kupereka mphamvu ku zida zochajira za AC kwa pafupifupi nthawi imodzi. Maola 5-8, kuonetsetsa kuti ntchito zofunika zolipirira zikupezekabe.

2. Tsatanetsatane wa Ntchito

Kugwiritsa kwa 2.1

Pulojekitiyi ndi njira yodziwika bwino yogwiritsira ntchito makina ochapira magetsi a solar-storage-EV.

Malo ochapira magetsi ku Ghana adakumana ndi mavuto atatu akuluakulu:

• Kufunika kwakukulu kwa chiwongola dzanja
• Kuchuluka kwa gridi yapafupi
• Mphamvu yamagetsi yosadalirika

Kudalira kokha pa gridi yamagetsi sikungathe kuthandiza zida zonse zochapira zomwe zimagwira ntchito nthawi imodzi. Kusintha kwa transformer yachikhalidwe kukanafuna ndalama zambiri komanso njira yayitali yomangira ndi kuvomereza.

Malo oimikapo magetsi a photovoltaic amapanga magetsi oyera pamalopo, pomwe makina osungira mphamvu ya batri amawonjezera magetsi pa nthawi yomwe magetsi amafunika kwambiri. Makinawa amaperekanso kusintha mwachangu kwadzidzidzi nthawi yomwe magetsi amagetsi amagetsi amatsekedwa.

Yankho ili limathandizira ntchito zochapira katundu wonse pansi pa mikhalidwe yabwinobwino komanso kusunga ntchito zofunika zochapira panthawi ya kusokonekera kwa magetsi. Limachepetsa kudalira magetsi, limachepetsa ndalama zogwirira ntchito, ndipo ndi loyenera makamaka malo ochapira magetsi amagetsi m'madera aku Africa omwe ali ndi ma gridi amphamvu ofooka kapena osakhazikika.

3. Ubwino Wofunika wa Pulojekiti

3.1 Overcomes Grid Capacity Limitations

Dongosolo losungira mphamvu la 125 kW/261 kWh limawonjezera mphamvu zochepa zomwe zimagwiritsidwa ntchito, zomwe zimathandiza kuti malo ochapira azigwira ntchito moyenera ngakhale kuti transformer ya 120 kVA yomwe ilipo ili ndi mphamvu zochepa.

3.2 Coordinated Solar, Storage, and Grid Operation

Dongosolo la photovoltaic, dongosolo losungira mabatire, ndi gridi yamagetsi zimagwirira ntchito limodzi mwanzeru kuti zithandizire kufunikira kwa chaji. Izi zimawonjezera kugwiritsa ntchito mphamvu ya dzuwa yoyera komanso zimachepetsa magetsi ogulidwa kuchokera ku gridi.

3.3 Continuous Operation During Power Outages

STS imalola kusinthana mwachangu pogwiritsa ntchito gridi komanso popanda gridi. Pakazima, makinawa amatha kupitiliza kupereka zida zochapira za AC kwa maola pafupifupi 5-8, kuonetsetsa kuti ntchito zofunika zochapira zikugwirabe ntchito.

3.4 Lower Infrastructure and Operating Costs

Yankholi limapewa mtengo wokwera komanso nthawi yayitali yogwiritsira ntchito yokhudzana ndi kukonzanso chosinthira chamagetsi. Kugwiritsa ntchito mphamvu ya dzuwa yokha, kuthandizira mphamvu zambiri, komanso kusunga mphamvu kumathandizanso kuchepetsa ndalama zamagetsi ndi ntchito za siteshoni kwa nthawi yayitali.
