Stability Enhancement of Decentralized Inverter Control Through Wireless Communications in Microgrids
Decentralized inverter control is essential in Distributed Generation (DG) microgrids for low deployment/ operation cost and high reliability. However, decentralized inverter control suffers from a limited system stability mainly because of the lack of communications among different inverters. In this paper, the authors investigate stability enhancement of the droop based decentralized inverter control in microgrids. Specifically, they propose a power sharing based control strategy which incorporates the information of the total real and reactive power generation of all DG units. The information is acquired by a wireless network (such as a Wi-Fi, ZigBee, and/or cellular communication network) in a decentralized manner.
