Energy Management System for grid integrated microgrid using Fuzzy Logic Controller

Abstract

When improving the operation of micro-grid systems, system reliability and effective efficiency are fundamental characteristics. To improve the quality of micro-grid systems, a new hybrid system model connected to the grid is formed, which includes a combination of photo-voltaic, wind turbines, asynchronous generator (induction), controllers and converters. The representation is implemented using the MATLAB/SIMULINK software package. To maximize the power generated based on the implementation of MPPT, (P&O) rule was used. The Transient state of the projected model is examined under different operating conditions. The model proposed in this Paper and its control strategy offer an adequate tool to optimize the performance of the micro grid. Design and execution of EMS with Fuzzy Logic controller for an AC / DC micro-grid system. This Paper proposes models, analysis and control of distributed energy sources and storage devices with MATLAB/Simulink. To improve the battery life cycle, the Fuzzy logic controller gives the desirable SoC. From the results, the system negotiated power balance and the battery "SoC" defend the coveted value to extend the life using controller for an AC/DC microgrid.
