Abstract

The paper considers the daily energy consumption variations for low demand season and high demand season weekdays and weekends in order to compare the corresponding fuels cost and analyse the operational efficiency of the PV/PW/DG/battery system for 24 hours period taken as control horizon. Previous researches have assumed a fixed load and uniform daily cost. A load following diesel dispatch strategy is used in this paper and the fuel costs and energy flows are analysed. The results show that a renewable energy system which combines the PV/PW/diesel/battery models achieves a better saving for the fuel during the high demand as well as the low demand seasons for days considered when compared to a model where the diesel generator satisfies the loads on its own.
