Load Frequency Controller Based on Particle Swarm Optimization for Isolated Microgird System

Load frequency control is a major issue in power systems operation. The performance of adaptive particle swarmoptimization (PSO), coefficient diagram method (CDM), and conventional integral (PI) controller are compared for an isolated single area non-re-heated turbine microgrid using both electric vehicles (EVs) and heat pump water heaters (HPs) as controllable loads. The dynamic response of LFC is studied using the MATLAB 2017a Simulink package to validate the effectiveness of the proposed scheme. The results indicated that the system with the PSO technique has better convergence and robustness than CDM in face of uncertainties due to load perturbations.
