Frequency Regulation of Interlinked Microgrid System Using Mayfly Algorithm-Based PID Controller

The primary goal of this article is to design and implement a secondary controller with which control the system frequency in networked microgrid system. proposed power comprises Renewable energy sources (RESs), energy-storing units (ESUs), synchronous generator. RESs include photovoltaic (PV) wind turbine generator (WTG) units. ESU composed flywheel battery. Because renewable are not constant nature, their values fluctuate from time time, causing an effect on flow variation tie line. nonlinear output balanced support ESUs. In order address situation, proportional integral derivative (PID) based Mayfly algorithm (MA) built. Comparing responses controllers genetic (GA), differential evolution (DE), particle swarm optimization (PSO) technique-optimized demonstrate superiority MA-tuned controller.. results validation comparisons reveal that implemented MA-PID delivers capable regulating under various load demand changes sources. A robustness analysis test was also performed determine effectiveness suggested technique (1%, 2%, 5%, 10%) step perturbation (SLP) ±25% ±50% nominal governor reheater constant).
