Fuzzy Logic Management Supervisor for Wind-Diesel-Battery Hybrid energy System

In this paper an operational control technique, based on using the Fuzzy Logic Energy Management Supervisor (FLEMS) is developed and applied to a proposed Wind-Diesel-Battery Hybrid System (WDBHS). The proposed system is modeled and simulated using MATLAB SIMULINK and FUZZY toolbox. The FLEMC is designed to work simultaneously with the commonly used ON-OFF controller, for optimizing the operation of the WDBHS under different wind speed. The proposed Fuzzy Logic Energy Management Controller (FLEMC) is proposed to supervise the input power and load demand continuously and to optimize the battery and diesel operation at various situations. The obtained results showed the great capability of the FLEMC in controlling the system.
