Application of AGPSO Algorithm in Frequency Controller Design for Isolated Microgrid

This paper presents the application of autonomous groups particles swarm optimization (AGPSO) algorithm for PID control design. The proposed control approach is used to design the controller of heat pump and plug-in hybrid electric vehicles for the frequency control of the isolated microgrid. This isolated microgrid is powered by diesel generator and solar energy sources. In addition, load frequency control (LFC) based on PID design for diesel generator is also proposed using AGPSO algorithm. The efficacy and effectiveness of proposed control design approach is evaluated under the influence of random load demand disturbances, and random solar power deviation. Further, the robustness and performance of the proposed control design are tested under parametric uncertainty, and multiple operating conditions of controllers. Finally, simulation results show the effectiveness and performance of the proposed control design in comparison to the published control design approach.
