Multi-Objective Model Reference Modified Adaptive PID Framework to Islanded Microgrid Control under Various Load Conditions

A multi-objective model reference modified adaptive PID controller is designed in this paper for voltage and current regulation of microgrid system under various load conditions. The performance of microgrid may deteriorate due to the variation of load dynamics. The goal of designed controller is to confirm the reliable performance under various load dynamics. The controller is designed based on selecting the desired reference model and controlling parameters. The designed controller effectivness is figured out against different 3-φ load dynamics such as consumer load, balance and unbalance load. The evaluation prove that the designed controller is capable of providing safe and stable performance for three-phase islanded microgrid system.
