A Review of Coordinated Control of DC Microgrids in PEDF Buildings

Microgrid is an important means to improve the utilization rate of distributed renewable energy, which is important for energy saving and emission reduction and realizing sustainable energy development. As DC microgrids can efficiently access energy sources such as photovoltaic and storage batteries, and DC equipment is increasing day by day, DC microgrids have a good development prospect. The application of DC microgrids in PEDF(photovoltaic, energy, DC, flexible) buildings can effectively utilize these advantages. The article firstly introduces the microgrid structure in the PEDF building. Secondly, it selects the flexible interconnection module of the microgrid, and combs the overall topology of the microgrid. Finally, it analyzes the control mode of each unit, and generalizes and summarizes the coordinated control mode of the microgrid in different working states.
