Abstract

This paper presents Automatic Generation Control (AGC) of a Single area and Multi area Autonomous Hybrid power system. The Autonomous power system comprises of thermal generation unit and Distributed genera-tion (DG) resources. The DG system consists of Wind turbine generator, Solar PV system, Diesel engine generator, Fuel cell with Aqua electrolyzer and Energy storage like Battery energy storage system.Controllers such as Propo-tional integral (PI), Proportional Integral Derivative (PID) and Two degree of Freedom PID controllers are treated as secondary controllers in the system. These controller gains are tuned with three Novel soft computing techniques such as Salp Swarm Algorithm (SSA), Grasshopper Optimization Algorithm (GOA), Ant Lion Optimization (ALO) and their performances are compared with most popular swarm intelligence technique such as Particle swarm opti-mization (PSO) for different loading circumstances. A comparative performance of various algorithms proves that the SSA Tuned 2DOFPID controller shows superior and satisfactory perfomance over other controllers.
