Advanced supervisor control for a stand-alone photovoltaic super capacitor battery hybrid energy system for remote building

This paper deals with a comprehensive supervisor control for a hybrid generation system. Such system works in island mode and comprises a photovoltaic panel and a battery/super capacitor energy storage system. The principal aims of the proposed supervisor are, firstly, to control the energy flow of the system in order to satisfy the load power demand, secondly, to manage the loads according to the power availability to preserve the battery state of charge and to prevent the system failure under any condition. The effectiveness of the proposed control strategy are tested by simulation in different operating situation. The simulation result shows the efficiency of the proposed control strategy, as it improves the energy balance of the system and increases its reliability.
