Multi-Objective Procedure for Optimal Integration of DC Microgrids in the Distribution Network

The combination of renewable energy sources, storage systems, and electric vehicle stations in a microgrid framework represents a useful solution for electric mobility integration in the distribution network. The coordination between control strategies of microgrids and distribution network is desirable for ensuring safe and cost-effective operation compliant with technical features of the involved infrastructures. In this study, a multi-objective mixed-integer linear programming procedure is proposed aiming at achieving both grid-side and microgrid-side technical optimal targets in the day-ahead scheduling of a radial distribution network integrating DC microgrids. The procedure is applied to a 33-nodes test network integrating 4 DC microgrids based on data of an experimental facility.
