Comparative Performance Analysis of Deregulated Hydrothermal System With Dual Mode Controller and Diverse Source of Generation Employing Imperialistic Competition Algorithm

This paper presents an accomplishment of Load Frequency Control (LFC) under deregulated environment using Imperialistic Competition Algorithm (ICA) based Dual Mode Controller (DMC). The Capacitive Energy Storage (CES) and Static Synchronous Series Compensator (SSSC) have been successfully used to improve the performance of the system dynamics. The optimization techniques are beneficial to the design of the Dual Mode Controller and overcome the drawbacks identified by the conventional controllers. The traditional Load Frequency Control system is adapted to interpret bilateral contracts on the system. The performance index is calculated by using the integral of the square of error technique to optimize the controllers of the Load Frequency Control system. The simulation analysis reveals that due to the presence of the Imperialistic Competition Algorithm-based Dual-Mode Controller, the performance of the system improves in terms of peak time, settling time, and overshoot, and also performance index is lesser than the system without the Imperialistic Competition Algorithm based Dual Mode Controller following a load disturbance in either of the areas.
