【 摘 要 】

Battery storage presents a considerable challenge in the development of hybrid PV/wind systems. In this work, we present a battery storage dimensioning for a hybrid PV/wind/diesel 3 kVA system. An economic study was carried out by fixing as a criterion the price minimization of one stored kWh. For this study we have taken into account the main battery technologies on the market: GEL batteries, AGM batteries, AGM deep cycle batteries, lithium-ion batteries and lithium iron phosphate batteries. In order to consider a realistic price, we have heeded losses in the battery. We have developed a suitable Matlab program allowing the price calculation of one stored kWh taking into account the battery losses. Two solutions have been identified.
