Coordinated AC/DC microgrid optimal scheduling [PDF]
2017 North American Power Symposium (NAPS), 2017 This paper proposes a coordinated optimal scheduling model for hybrid AC/DC microgrids. The objective of the proposed model is to minimize the total microgrid operation cost when considering interactions between AC and DC sub-systems of the microgrid network.
