MPPT Methods in Hybrid Renewable Energy Systems

Abstract

In this chapter, the most used MPPT methods in photovoltaic and wind turbine systems are presented. The most used control technique in optimization consists in acting on the duty cycle automatically to place the generator at its optimal value whatever the variations of the metrological conditions or sudden changes in loads which can occur at any time. In general, there are two types of these algorithms: classical and advanced. For each method presented, it is given different details as the concept, the principle, the algorithm, the flowchart, blocks schemes under MATLAB/Simulink and for some methods an application with obtained results in MATLAB/Simulink. A comparison between different MPPT methods is made. At the end of the chapter, an overview of some important proprieties of the most used MPPT methods for Photovoltaic and wind systems has been summarized in different tables. An accent is given on Global Maximum Power Point Tracking (GMPPT) techniques of photovoltaic system under partial shading conditions. Readers are encouraged to use these algorithms to test each example.
