Frequency Control of Isolated Network with Wind And Diesel Generators by Using Frequency Regulator

Due to the recent expansion of renewable energy applications, wind energy conversion is receiving much interest all over the world. However, output fluctuations of wind generators cause network frequency variations in power systems. This can decrease the power quality and then cause a restriction of wind farm installation, especially in an isolated network, for example, electrical power system in a small island. Therefore the problem of output fluctuation needs to be solved for Expanding further the wind energy conversion. This paper presents a new application frequency regulator to an isolated network with a high penetration no storage wind diesel system for improving the network frequency quality. The validity of the proposed controller is evaluated by computer simulation analysis using Matlab/Simulink.
