1. Project Overview

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.

Chinoshandura magetsi chemuno chine simba rekushandisa simba chete 120kVANekuda kwekusakwana kwegrid uye kudzimwa kwemagetsi nguva nenguva, grid iripo haigone kutsigira nzvimbo dzese dzekuchaja dzinoshanda nesimba rakazara, zvichideredza zvakanyanya kugona kwekuchaja kwechiteshi uye kushanda zvakanaka kwacho.

Kuti vagadzirise kusakwana kwesimba regrid pamwe nemagetsi asingavimbike, mutengi akasarudza yedu 125 kW/261 kWh bhatiri rekuchengetera simba kabhineti, yakasanganiswa ne STS chinja chekuchinja chinomira uye sisitimu yemotokari ye photovoltaic.

Mumamiriro ezvinhu akajairwa egrid, solar system, bhatiri storage system, uye utility grid zvinoshanda pamwe chete kutsigira michina yekuchaja iri pamagetsi akazara. Kana grid ikadzima, system inopedzisa shanduko kubva pagrid-connected kuenda ku off-grid operation mukati mesekondi imwe chete. Macharger eDC fast ane simba guru anodzimwa kwenguva pfupi, ukuwo system ichiramba ichipa simba kumidziyo yekuchaja yeAC kweinenge nguva. 5-8 maawa, kuve nechokwadi chekuti mabasa ekuchaja akakosha anoramba aripo.

2. Project Details

2.1 Chikumbiro

Chirongwa ichi chinoshandiswa zvakanyanya mukutengeserana kwemagetsi ezuva akabatanidzwa ekuchaja magetsi emagetsi emagetsi.

Nzvimbo yekuchaja muGhana yakatarisana nematambudziko makuru matatu:

• Kudiwa kwekuchaja kwepamusoro-soro
• Kukwanisa kwegridi yemunharaunda kushoma
• Simba remagetsi risingavimbike

Kuvimba chete negrid yemagetsi kwaisagona kutsigira michina yese yekuchaja inoshanda panguva imwe chete. Kuvandudzwa kwesimba re transformer kwakajairika kwaizoda mari yakawanda uye kuvaka kwakareba uye kubvumidzwa.

Nzvimbo yemagetsi inoburitsa magetsi akachena zvakananga panzvimbo iyi, ukuwo sisitimu yekuchengetedza simba remabhatiri ichibatsirawo grid panguva dzekuchaja zvakanyanya. Sisitimu iyi inopawo shanduko nekukurumidza panguva yekudzima kwegrid.

Mhinduro iyi inotsigira mashandiro ekuchaja zvizere mumamiriro ezvinhu akajairwa ukuwo ichichengetedza mabasa ekuchaja akakosha panguva yekukanganiswa kwemagetsi. Inoderedza kuvimba nemagetsi emagetsi, inoderedza mari yekushandisa, uye inonyanya kukodzera nzvimbo dzekuchaja dzemagetsi dzekutengeserana munzvimbo dzeAfrica dzine magridi emagetsi asina kusimba kana asina kugadzikana.

3. Zvakanakira Zvikuru zvePurojekiti

3.1 Overcomes Grid Capacity Limitations

Sisitimu yekuchengetera simba ye125 kW/261 kWh inowedzera huwandu hushoma hwemagetsi, zvichiita kuti nzvimbo yekuchaja ishande zvakanaka pasinei nekukwanisa kushoma kwetransformer iripo ye120 kVA.

3.2 Coordinated Solar, Storage, and Grid Operation

Sisitimu yemagetsi inobuda nemagetsi, sisitimu yekuchengetera mabhatiri, uye grid yemagetsi zvinoshanda pamwe chete nehungwaru kutsigira kudiwa kwekuchaja. Izvi zvinowedzera kushandiswa kwesimba rezuva rakachena uye zvinoderedza magetsi anotengwa kubva pagrid.

3.3 Continuous Operation During Power Outages

STS inobvumira kushandura grid nekukurumidza uye kunze kwegrid. Panguva yekudzima, sisitimu inogona kuramba ichipa michina yekuchaja yeAC kwemaawa angangoita mashanu kusvika masere, zvichiita kuti mabasa ekuchaja arambe achishanda.

3.4 Lower Infrastructure and Operating Costs

Mhinduro iyi inodzivirira mari yakawanda uye nguva yakareba yekushandisa inobatanidzwa nekuvandudza transformer yemagetsi. Kuzvishandisa kwezuva, rutsigiro rwemagetsi akawandisa, uye kuchengetedza simba zvinobatsirawo kuderedza mari yemagetsi yenguva refu uye yekushandisa kwechiteshi.
