1. Pulojekiti ya Project

Pulojekitiyi ikuphatikizapo kukhazikitsidwa kwa makina osungira magetsi a AC omwe ali ndi mphamvu ya 4S ku Cambodia. Ikuphatikizapo inverter ya 125kW photovoltaic ndi makina atsopano osungira magetsi, zomwe zimathandiza kuti pakhale magwiridwe antchito awiri: 'kudzipangira wekha kuti udzigwiritse ntchito ndi mphamvu yowonjezera yolowera mu gridi' ndi 'mphamvu yosungira magetsi yochokera ku gridi'. Kapangidwe ka makinawa kamaganizira momwe kasitomala amagwiritsira ntchito magetsi (pafupifupi 14.8kWh patsiku, maola ogwirira ntchito 8:00–20:00) ndipo imathandizira kugulitsa magetsi ochulukirapo mpaka 15kWh ku gridi tsiku lililonse.

2. Zambiri za Project

Gusaba Akazi Gashya

Dongosololi limagwira ntchito m'njira ziwiri:

Njira yolumikizidwa ndi gridi:

- Magalimoto a masana amaika patsogolo mphamvu ya photovoltaic;

- Kuchulukitsa kwa PV kumayambitsa mabatire osungira kaye;

– Batire ikadzaza, mphamvu ya PV yochulukirapo ikhoza kugulitsidwa ku gridi (yotsekedwa pa 15kWh/tsiku);

Mu nthawi ya usiku kapena mvula yamkuntho, kutulutsa kwa batri kumapereka mphamvu mpaka SOC itatsika pansi pa 10%, pomwe makinawo amatseka ndikusintha kupita ku magetsi operekera magetsi;

Kuchaja mabatire kuchokera ku magetsi operekedwa ndi magetsi n'koletsedwa.

Njira Yoyimirira Yopanda Gridi:

Pamene magetsi akuzima, makina osungira mphamvu amasinthira okha ku ntchito yopanda gridi kuti apereke katundu wofunikira;

Dongosolo limazima pamene batire ikutuluka pansi pa SOC < 10%, zomwe zimapangitsa kuti katundu asamayende bwino.

3. Ubwino wa Ntchito

Kukonza Zachuma: Kumakulitsa kudzipangira ndi kudzigwiritsa ntchito kuti muchepetse ndalama zomwe mumagwiritsa ntchito pamagetsi; kumathandiza kuti magetsi azigwiritsidwa ntchito tsiku ndi tsiku kuti mupeze ndalama zowonjezera.

Chitetezo cha Mphamvu: Chimapereka mphamvu yosungira magetsi kunja kwa gridi yamagetsi nthawi ya kuzima kwa main, kuonetsetsa kuti katundu wofunikira akuyenda bwino kwakanthawi kochepa.

Kukonza Ndondomeko Mwanzeru: Kumasintha njira zochajira/kutulutsa mphamvu zokha kutengera malire a SOC (10%–100%) kuti batire likhale ndi moyo wautali.

Kugwirizana Kwambiri: Ma interface olumikizirana okhazikika amathandizira kuphatikizana ndi machitidwe a PV omwe alipo komanso zida zoyezera gridi.

Kusintha Kwakomweko: Ndondomeko yowongolera yosinthidwa yokonzedwa kuti igwirizane ndi kuchuluka kwa makasitomala omwe amagwiritsa ntchito tsiku ndi tsiku (pafupifupi 14.8kWh) ndi maola ogwirira ntchito, zomwe zimaletsa kuperekedwa mopitirira muyeso.
