Impact of Renewable Sources in AGC for Two Area Interconnected Power System

The integration of non-conventional energy sources like wind energy for economical operation is not just increasing the size of the modern power system but also the complexity in meeting the load demand. Hence, a better control scheme and optimization technique is required to maintain the system equilibrium. In the current paper, a two interconnected area electrical power system (both the areas comprising of a hydro power plant, thermal power plant, gas power plant and doubly fed induction generator (DFIG)) has been analyzed. A Proportional-Integral-Derivative (PID) controller with a derivative filter has been used to manage the damping in the system. Further, a new meta-heuristic Hybrid Salp Swarm Differential Evolution Algorithm (HSSDEA) optimization technique has been used to optimize the controller gain.
