Design of a Robust Integral Sliding Mode Controller Based on an Enhanced Reaching Law for DC Microgrids

For better power-sharing in DC microgrids, an improved reaching law-integral sliding mode controller (ERLISMC) is presented in this study. The primary goal is to maintain the system's power balance. The most crucial sign is a steady voltage on the DC-bus for maintaining a power balance (PB). As a result, another goal of this work is to keep the DCbus voltage constant. A solar photovoltaic (PV) system, a battery, and DC loads are all part of the planned DC microgrid. The suggested ERLISMC method is used to regulate the output of each unit. The Lyapunov theory is used to determine the system's stability. At last, simulation results are shown to illustrate the suggested controller's performance on the proposed microgrid. The performance is also connected with a constructed conventional reaching law-ISMC to demonstrate its use (CRL-ISMC).
