Load Frequency Control in Power Systems Using Improved Particle Swarm Optimization Algorithm



The purpose of load frequency control is to reduce transient oscillation frequencies than its nominal value
and achieve zero steady-state error for it.A common technique used in real applications is to use the
proportional integral controller (PI). But this controller has a longer settling time and a lot of Extra
mutation in output response of system so it required that the parameters be adjusted as appropriate . In this
paper, we aim to design a system based on PI controllers using improved particle swarm optimization
algorithm for load frequency control .Multi-population approach and local search to improve the
optimization algorithms is used and displayed. That this approach will lead to accelerating the achievement
of results, preventing entrapment in a local minimum, and get better system output compared with similar
