An Effective Control Strategy for Pitch control of Wind Energy System Connected with Grid

Abstract

Recently the main concern all over the world is carbon emission reduction and due to this renewable energy sources are the main point of attraction for the power generation. Especially wind energy into the electrical power grid is extensively increased, the influence of the wind turbine system on the voltage stability and frequency becomes more and more significant. Wind turbine rotor has different types of loads and these loads results in fatigue and vibration in blades. These loads and losses can overcome by using a good pitch controller. As we know that energy extracted is limited according to Betz law but with the help of good pitch angle controllers it is possible to get desired output in certain conditions. A maximum performance can be obtain by designing a good pitch angle controller. A system with wind turbine generator system connected with grid is designed and simulated in Matlab software with the PID control system and the results are evaluated and by analysing these results some future analysis can be planned.
