Robust, Accurate, and Fast Decentralized Power Sharing Mechanism for Isolated DC Microgrid Using Droop-Based Sliding-Mode Control

In this paper, a droop-based sliding mode controller (DBSMC) is designed for power sharing in an isolated DC microgrid (DC MG), with improved nonlinear droop model, the presence of bounded structured uncertainties and external disturbances. The proposed DBSMC strategy does not require any communication link. design process such that trade-off between two factors proportional precise voltage regulation reaches minimum possible. creative greatly reduced control action stress, way that, occurrence various model compensated by applying small intelligent changes parameters, using fuzzy approximator. To evaluate efficiency controller, simulations are performed on MG DC-DC buck configuration MATLAB software. Finally, real-time digital simulation results utilizing system simulator (RTDS) corroborate performance controller. obtained from RTDS verify robust, accurate fast function variable operating conditions, parametric
