A Coordinated Energy Management Framework for DNO Ensuring Financial Benefits of MGOs

The distributed energy resources (DERs) operation in the distribution network and microgrid (MG) requires a coordinated framework for optimal power sharing due to their different ownership. Specifically, the DERs present within MG should operate to ensure the financial benefit of the respective MG operators (MGOs). This paper proposes a coordinated energy management framework for a distribution network operator (DNO) and set of MGOs. Indeed, it provides opportunities for the MGOs to participate in the power-sharing framework established by the DNO and minimize their power-sharing costs with the DNO. The proposed framework is modeled as the mixed integer linear programming problem and solved using the Gurobi solver. The comparative results are illustrated for a modified IEEE-33 bus distribution network connected to three MGs. MGOs net power share cost reduction is observed when the DERs within MGs are economically scheduled.
