Abstract

In this paper, we have designed a micro-generation energy system obtained by interconnecting a wind turbine with a photovoltaic generator and characterized by very low voltage (VLV) node coupled to a battery storage and DC loads. The control strategies of the sources are based on power, voltage and current control with maximum power point tracking (MPPT). Experiments based on a physical emulator of the hybrid system with a lead acid accumulator and its DC load is considered. The development of experiments is necessary to validate theoretical studies. The real time supervision and the energy management of the hybrid system is presented and detailed. Experimental results are presented and discussed showing the relevant behavior of the energy management strategy.
