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

Abstract

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 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.

Hybrid technique for load frequency control of renewable energy sources with unified power flow controller and energy storage integration

“…As, it has various regions, every zone has a regulator for frequency control, and interface among regulators may realize via tie line signals among dissimilar areas. 23,24 In this manuscript, the MASAAI approach is proposed to minimize load frequency deviations at three-area hybrid power system. The main objective of this manuscript is to ensure as well as prove the MASAAI robustness approach with the PID controller and to enhance the performance of frequency deviation as well as tie line power in several load conditions in the presence of system non-linearities.…”
