LFC DYNAMIC RESPONSE IMPROVEMENT USING FUZZY LOGIC BASED CONTROL OF TCPS IN DEREGULATED POWER SYSTEM

This paper deals with application of load frequency control (LFC) to deregulated power system and makes a maiden attempt to provide a new practical AGC model to cater to the needs of a modern restructured hydrothermal power system. FACTS device like TCPS can be used to regulate the power flow in the tie-lines of interconnected power system. A simple fuzzy logic controller is designed to help damping of frequency and tie line power oscillations due to different load disturbances.
