Abstract:

Load Frequency Control (LFC) is one of the important issues in power system operation. The main objective of LFC is to keep the frequency and tie-line power close to their nominal values in case of disturbances. In this paper, two methods based on parallel adaptive of a scaled fuzzy with conventional technique to control the frequency of a power system is proposed. A particle swarm optimization (PSO) method is used to optimize the scales of fuzzy-PI/PD and gains tuning of PI/PD controllers. Two equal interconnected power system areas are used as a test system. As the results, the simulation has shown the effectiveness of the proposed controller compared with different PID and scaled fuzzy controllers in terms of speed response and damping frequency.
