Model Reference Modified Adaptive PID Controller Design for Voltage and Current Control of Islanded Microgrid

摘要

A model reference modified adaptive PID controller is designed in this paper for voltage and current control of islanded microgrid. Microgrid is a discrete energy system consisting of distribution loads. The distribution loads are unknown and uncertain in parameters that may produce the voltage and current deviation of microgrid. The objectives of designing controller is to obtain the high tracking voltage and current against distribution loads. Design of the controller is done by choosing the reference model, set the adjustment mechanism and controlling parameters. The designed controller performance is tested under the action of dynamic, harmonic, asynchronous machine loads using MATLAB Simulation. The investigations show that the designed controller is able to provide high tracking performance for voltage and current control of the islanded microgrid system.
