Advanced Intelligent Fuzzy Control of Standalone PV-Wind-Diesel Hybrid System

The aim of this paper is to study the modelling and intelligent fuzzy control of a stand-alone hybrid energy system based on solar-wind-diesel with battery. The renewable sources are major components of a standalone hybrid system as a combining photovoltaic with the wind turbine. Each component of these systems has been modelled and implemented in MATLAB/Simulink software. In order to improve power quality and reduce unwanted fluctuations of system quantities under different operating conditions an intelligent fuzzy control is proposed in this work. The capabilities of this designed intelligent control system on the stabilization of system voltage and frequency are tested under different operating conditions and compared to standard PID controllers. The superiority of the proposed intelligent fuzzy control system over PID controllers is demonstrated by the simulation benchmark tests.
