Energy Management Strategy of Islanded Hybrid DC/AC Microgrid with Energy Storage System

Abstract

Hybrid AC/DC microgrids are increasingly used in power systems for remote industrial, commercial and residential plants. To maintain low generation cost while reducing carbon emissions, the combinational usage of conventional gas turbine generator and solar photovoltaic (PV) is usually preferred, where the problems of unsatisfying fuel efficiency and renewable intermittency are identified as the key challenges. To enhance the fuel efficiency of microgrid and effectively mitigate renewable intermittency, this paper proposes an advanced energy management strategy. It ensures high fuel efficiency and produces a virtual inertia for the microgrid. Moreover, fast DC-link voltage regulation and seamless transition between grid-forming and grid-following modes can be achieved. The stability of controllers employed in the proposed strategy is proven. The efficacy of the proposed energy management strategy is verified by simulation results.
