Design Fuzzy PI Based Controller for Load Frequency Control of Thermal Thermal Area Interconnected Power System

This paper presents how to design proportional integral controller and Fuzzy PI based controller for efficiently load frequency control. Loads on the electrical system always vary in relation to that time, which results in diversity of frequency, causing frequency control problems to be loaded. The frequency difference is highly undesirable and the maximum allowable difference in frequency is ±0.5 Hz. This paper load frequency control is done by PI controller, which is a conventional controller. This type of controller is slow and the controller does not allow the designer to keep in mind the potential change in operating conditions and non linearity in the generator unit. To overcome these flaws, new intelligent controllers like Fuzzy PI Controller are presented to extinguish tie line power due to deviation in frequency and various load disturbances. The effectiveness of the proposed controller has been confirmed using the MATLAB SIMULINK software. The results show that the PI fuzzy controller provides fast response, little undershoots and negligible overshoot with small state transfer time to reach the final stable position.
