Load Frequency Control of a Hybrid Wind Diesel System Using Fuzzy Logic Control

S Siddik, A Selva Vinayagam, R Gopinath

Load Frequency control (LFC) in power system is undergoing a lot of changes due to the rapidly growing demand and due to various renewable generation integration to the existing system. This work proposes an LFC scheme based on Fuzzy Logic Control for a hybrid wind-diesel power system. Therefore the objective of this LFC is to minimize system frequency deviations and tie line power changes. The wind power being a highly intermittent source imposes additional power imbalance and frequency deviation problems to the hybrid system. A serious care has been taken to study characteristics of such a system under isolated conditions. Based on the studies made a FLC based LFC scheme for the isolated hybrid wind diesel power system is developed and the performance of the scheme is verified using MATLAB/SIMULINK
