Abstract: The renewable resources integration in power system became primordial interest, their integration reduces global warming especially greenhouse gas. The clean energies integration for standalone power systems need a choose of adapted renewable energy according to the weather conditions, each region and also according to the installation cost, generally solar and wind resources are complemented. The intelligent management is necessary for this hybrid system using a modern technical method which is able to manage the power flow to electric load and/or store exceeding of power production in storage dispositive, it need also an adapted architecture in order to get a good power quality and to reduce the global cost of the system, in this context, an intelligent energy management control is necessary, the intelligent supervisory based on fuzzy logic control must manage the system in order to answer several stakes: the energy efficiency of the system for the smooth-running production-consumption and the service continuity and reliability. This work provides a fuzzy logic to control multisource system's according to the weather conditions and to manage the power flow generation. The study was implemented under MATLAB/Simulink and the simulation results with fuzzy logic control are compared with another result with maximum power point tracking based proportional integral derivative controller, the study is applied in Bechar (in the south of Algeria). The results show a very good performance, the power quality produced is better when the system is managed by a fuzzy logic control, this intelligent management control is able to use the energy produced to supply the load and/or to battery charge without a power loss and discontinuity.

Keywords: energy management, fuzzy logic controller, hybrid system, multi-source system, renewable energies, standalone system
