Maximum Power Control of Hybrid Wind‐Diesel‐Storage System

Abstract

Extraction of maximum wind power of variable speed wind turbines in hybrid wind‐diesel‐storage system (HWDSS) is considered due to economical purposes. The proposed control algorithm utilizes extended fuzzy‐linear matrix equalities (FLMEs) systems design of stabilizing fuzzy controllers for nonlinear systems described by Takagi‐Sugeno (TS) fuzzy models. The algorithm maximizes the power coefficient for a fixed pitch. Moreover, it reduces the voltage ripple and stabilizes the system over a wide range of wind speed variations. The control scheme is tested for different profiles of wind speed pattern and provides satisfactory results.
