Operational cost optimization for renewable energy microgrids in Mediterranean climate

This paper is concerned with the energy management of a micro-grid composed of photovoltaic/ wind/diesel sources used to supply household loads. The control strategy manages the power flow between the power sources and the loads, which ensures the minimization of the installation operating cost, the safe operating for the battery bank while minimizing the use of the diesel engine. The strategy is tested using measured data of some climatic parameters of a Mediterranean area (Northern Tunisia), showing its efficiency in fulfilling the fixed objectives and respecting the criteria of the control strategy.
