Comparative Analysis of Different Optimization Technique Based PID Controller for Isolated Microgrid

In present network of electricity, micro grid’s are mostly used in power system due to their technical, economic and environmental advantages.Because of the variable nature of loads and the irregular behavior of inexhaustible energy resources, the frequency variations occur in micro grid particularly in the isolated way of working. In this paper, for controlling the frequency of the load in isolated micro grids which consists of many resources of energy, Grey Wolf Optimizer (GWO) algorithm is used. By the utilization of given evolutionary algorithm the variables of suggested GWO based PID Controller has improved. To control the frequency of the load of microgrid the GWO tuned PID controller presents a superb execution. The model is done in MATLAB and the output results are corelated with other optimization methods based PID controller. The end outcome which are obtained show the supremacy of the suggested method in reducing the frequency variations.
