摘要
A truly distributed and autonomous control strategy is proposed for the FREEDM System-a power electronics based distribution grid. The proposed control strategy requires no communication between and among all grid assets. By utilizing available local quantities (V, f) as a way to communicate among all connected devices, the strategy contains a novel dual droop control loops between the medium voltage feeder and dispatchable resources such as energy sources, storages. The proposed control is put forward to achieve intelligent power management of the FREEDM system under all modes of operation. This is a pre-requisite to use FREEDM system as a transformative platform for plug-and-play of energy (aka Energy Internet). Simulation results verify the autonomous nature of the proposed control.
