Compositional Power Flow for Networked Microgrids

In this paper, a compositional power flow (ComPF) is devised for networked microgrids to take into account power sharing and voltage regulation between microgrids while preserving data privacy of each microgrid. The main contributions of the ComPF include: 1) devising an advanced-droop-control-based power flow to incorporate distributed energy resources and load droops within microgrids and 2) establishing an adaptive-secondary-control-based compositional power flow scheme to account for power sharing and voltage regulation between microgrids. As an inherently distributed method, the ComPF supports plug-and-play of microgrids and preserves customer privacy.
