Abstract

In this study power management strategies for a novel distribution level microgrid which is being developed at FREEDM center - Green Hub- are investigated. The Green Hub is a 12 kV distribution circuit with high level PV penetration. A large scale dispatchable distributed energy storage device (DERD) has also been added to this system to provide the additional power that is needed during islanding conditions. The high level penetration of photovoltaic (PV) units potentially necessitates new controls for both islanded and grid-connected X operation modes and smooth transition between the two modes to enable the best utilization of the microgrid resources. In this paper, state-of-the-art power management strategies have been investigated for this purpose. The Green Hub has been simulated using simpower/simulink of MATLAB, and it is used to assess the performance of the centralized control scheme considered.
