Assessment of Optimal PID Tuning Controllers for Load Frequency Control
Authors: ,
Abstract: This paper presents two methods for designing the parameters of PID controller, the first is the Particle Swarm Optimization technique and the second is a Bacterial Foraging Optimization Algorithm. These two methods are used to search for optimal parameters of the controllers to minimize the performance index. A two area thermal system is considered for design and analysis. In each area LFC monitors the system frequency deviations and tie line power which gives the net change in area control error. If the ACE is made to zero, then both tie line power and frequency will be forced to zero. The superiority of the proposed approach has been demonstrated by comparing the results and is observed that it could be easily extended to other global optimization problems.
