Decentralized Inverter Control in Microgrids Based on Power Sharing Information Through Wireless Communications
For the future smart grid, decentralized inverter control is essential in Distributed Generation (DG) micro-grids where a powerful central controller is unavailable for cost and reliability concerns. However, decentralized inverter control suffers from limited system stability mainly because of the lack of communications among different inverters. In this paper, the authors investigate the stability enhancement of the droop based decentralized inverter control in micro-grids. Specifically, they propose a power sharing based control strategy which incorporates the information provided by a wireless network to improve system stability.
