Abstract

Recently more renewable distributed generations and various demands are expected to connect in distribution networks directly to reduce processes of multiple reverse conversions. The hybrid AC/DC micro grid is constructed to achieve efficient integration of distributed energy resources (DER) and energy storage system (ESS) into the existing power systems. However, the Energy Management System (EMS) faces new challenges because of the unique features of the micro grid. In order to handle these DGs and controllable loads, a hierarchical energy management strategy consists of multi-agents is proposed to realize efficient and flexible operation of hybrid grid and optimal power flow.
