Microgrid Frequency Stabilization Study with Approaching SCA Tuned Fuzzy Controller

The grid with fractional MW rated is termed as microgrid. The microgrid is normally located at the distribution level and able to generate electrical energy with penetrating different renewable source-based generating units. The renewable energies such as wind power, solar energy, tidal power, geothermal power are now most convenient source to produce electricity. The limitations of renewable power generating plants are uncertainty in wind velocity and variation in the solar radiation power. These uncertainties produce abnormal in the microgrid frequency and also in voltage. This article has employed a noble fuzzy PID approach to manipulate frequency oscillation issues under such uncertainties. The controller is also implemented to maintain standard frequency environment under frequency load dynamic issues. Further, the controllability of the proposed fuzzy controller over standard PID and PI controllers is studied by different results and responses. The research has also applied a sine cosine algorithm (SCA) to get the most fit parameters of the controller. Finally, the effective action of the suggested SCA technique over PSO and GA has been synthesized to validate superiority of the proposed algorithm.
