Optimized Strategy for Enhancing DC-Microgrid's Performance using Local Unimodal Sampling (LUS) optimization algorithm

Abstract

Due to its great benefits, the implementation of DC Microgrids has been increasing over the past few years. This led to attracting the researchers to improve its control to maximize its performance as possible. Droop resistance control is one of the most used control approaches. In this paper, Local Unimodal Sampling (LUS) optimization is used to optimize the values of droop resistance to ensure the best current sharing. Also, optimization is carried out to optimize the gains of fractional order PID controller of the droop controller which grantee ideal current sharing and minimized voltage deviation.
