ROLE BASED ACCESS CONTROL WITH BMS ADAPTABILITY FOR MICRO GRIDS ON INVERTERS

Abstract

This paper proposes a robust control strategy for power sharing among parallel inverters in a single-phase AC microgrid. It combines variable incline and discrete droop control with proportional-resonant loops to ensure both dynamic stability and harmonic suppression. A two-time-scale model is developed, separating slow frequency regulation from fast power-sharing and voltage control. The system remains input-to-state stable despite uncertainties, with tracking errors shown to be asymptotically bounded. Fuzzy logic enhances flexibility and adaptability, while optimal gain tuning ensures fast recovery from disturbances. Simulation results validate the method’s effectiveness, demonstrating accurate, stable, and responsive power sharing under varying conditions within a hierarchical, real-time monitored microgrid environment.
