Optimization of LFC controller of two area system integrated with wind energy using HSA

摘要

Incorporation of wind energy into power systems has gathered substantial momentum globally due to its abundant supply and environmental benefits. Despite its numerous benefits, wind power in grid integration poses many challenges. The non-dispatchable and inherent intermittent qualities of wind energy not only insert additional fluctuations to the existing frequency deviation, they also reduce frequency stability by decreasing the regulation capability and the inertia. This paper presents the significance of these effects, which causes a larger frequency deviation in the proposed system. In this paper optimization algorithm used to optimize PID controller is Harmony Search Algorithm (HSA). The simulation and analytical results represented here provide guidance on calculating maximum wind power penetration level using frequency deviation limit.
