1. Qhov 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.

Lub transformer hauv zos muaj peev xwm tsuas yog 120kva uaVim tias lub zog fais fab ntawm lub network muaj tsawg thiab cov hluav taws xob tsis ua haujlwm ntau zaus, cov khoom siv fais fab uas twb muaj lawm tsis tuaj yeem txhawb nqa txhua qhov chaw them hluav taws xob uas ua haujlwm ntawm lub zog tag nrho, ua rau lub chaw them hluav taws xob muaj peev xwm them thiab ua haujlwm tau zoo tsis zoo.

Txhawm rau daws qhov teeb meem tsis txaus ntawm lub zog hluav taws xob thiab kev muab hluav taws xob tsis txhim khu kev qha, tus neeg siv khoom tau xaiv peb Lub txee cia roj teeb 125 kW/261 kWh, ua ke nrog ib STS static hloov pauv thiab lub tshuab photovoltaic carport.

Nyob rau hauv cov xwm txheej ib txwm muaj ntawm lub network, lub hnub ci system, lub roj teeb cia system, thiab lub network hluav taws xob ua haujlwm ua ke los txhawb cov khoom siv them fais fab kom muaj zog tag nrho. Yog tias lub network tsis ua haujlwm, lub system ua tiav kev hloov pauv ntawm kev sib txuas nrog lub network mus rau kev ua haujlwm tawm ntawm lub network hauv ib vib nas this. Cov chargers DC ceev ceev muaj zog heev raug kaw ib ntus, thaum lub system txuas ntxiv muab hluav taws xob rau cov khoom siv them AC li ntawm 5-8 teev, xyuas kom meej tias cov kev pabcuam them nqi tseem ceeb tseem muaj.

2. Cov ntsiab lus ntawm qhov project

2.1 Daim Ntawv Thov

Qhov project no yog ib qho kev siv lag luam ib txwm muaj ntawm lub hnub ci-cia-EV them hluav taws xob.

Lub chaw them fais hauv Ghana ntsib peb qhov teeb meem loj:

• Kev xav tau them siab tshaj plaws
• Muaj peev xwm tsawg hauv zos
• Kev siv hluav taws xob tsis txhim khu kev qha

Kev cia siab rau lub zog fais fab xwb yuav tsis tuaj yeem txhawb nqa txhua yam khoom siv them hluav taws xob uas ua haujlwm tib lub sijhawm. Kev txhim kho lub peev xwm ntawm lub transformer ib txwm yuav xav tau kev nqis peev ntau thiab kev tsim kho thiab kev pom zoo ntev.

Lub chaw nres tsheb photovoltaic tsim hluav taws xob huv ncaj qha ntawm qhov chaw, thaum lub kaw lus khaws cia roj teeb ntxiv rau lub grid thaum lub sijhawm xav tau them ntau. Lub kaw lus kuj tseem muab kev hloov pauv thaum muaj xwm txheej ceev ceev thaum lub grid tsis ua haujlwm.

Cov kev daws teeb meem no txhawb nqa kev them nqi puv ntoob hauv qab qhov xwm txheej ib txwm muaj thaum tseem tswj hwm cov kev pabcuam them nqi tseem ceeb thaum muaj kev cuam tshuam hluav taws xob. Nws txo qhov kev vam khom rau hluav taws xob ntawm cov tuam txhab hluav taws xob, txo cov nqi khiav lag luam, thiab tshwj xeeb tshaj yog tsim rau cov chaw them nqi EV lag luam hauv thaj chaw Africa uas muaj cov hluav taws xob tsis muaj zog lossis tsis ruaj khov.

3. Cov Txiaj Ntsig Tseem Ceeb ntawm Qhov Project

3.1 Overcomes Grid Capacity Limitations

Lub tshuab khaws cia hluav taws xob 125 kW/261 kWh ntxiv rau qhov kev muab hluav taws xob tsawg, ua rau lub chaw them hluav taws xob ua haujlwm tau zoo txawm tias lub transformer 120 kVA uas twb muaj lawm muaj peev xwm txwv.

3.2 Coordinated Solar, Storage, and Grid Operation

Lub tshuab photovoltaic, lub tshuab khaws roj teeb, thiab lub network hluav taws xob ua haujlwm ua ke nrog kev txawj ntse los txhawb kev xav tau them hluav taws xob. Qhov no ua rau kev siv lub zog hnub ci huv si ntau ntxiv thiab txo cov hluav taws xob uas yuav los ntawm lub network.

3.3 Continuous Operation During Power Outages

Lub STS ua rau muaj kev sib txuas nrog lub grid thiab kev hloov pauv tawm ntawm lub grid sai. Thaum lub sijhawm tsis muaj hluav taws xob, lub kaw lus tuaj yeem txuas ntxiv muab cov khoom siv them AC li ntawm 5-8 teev, kom ntseeg tau tias cov kev pabcuam them hluav taws xob tseem ua haujlwm tau.

3.4 Lower Infrastructure and Operating Costs

Cov kev daws teeb meem no zam kev siv nyiaj ntau thiab lub sijhawm siv ntev uas cuam tshuam nrog kev txhim kho lub tshuab hluav taws xob. Kev siv hluav taws xob los ntawm lub hnub, kev txhawb nqa thaum muaj hluav taws xob ntau, thiab kev khaws cia hluav taws xob kuj pab txo cov nqi hluav taws xob thiab kev siv nyiaj ua haujlwm mus sij hawm ntev ntawm lub chaw nres tsheb.
