Operational cost optimization for renewable energy microgrids in Mediterranean climate

Abstract

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.

Energy Management Strategy for an Autonomous Hybrid Power Plant Destined to Supply Controllable Loads

“…This paper is a continuation of previous published papers [ 19 , 20 ]. In fact, it focuses on the energy management strategy (EMS) of an autonomous hybrid plant destined to supply controllable loads with the required electrical power.…”

“…In previous papers [ 19 ], some of the authors of this paper have studied the energy and water management of a renewable based plant. Moreover, in [ 20 ], the authors studied the optimization of a hybrid plant using the genetic algorithm. The contributions of this paper are the following: The authors apply the fuzzy logic to decide on the switching time of the switches that links the hybrid plant’ components ( Figure 1 ).…”
