Fault-tolerant distributed load/frequency supervisory strategies for networked multi-area microgrids

Abstract

A distributed supervisory strategy for addressing load/frequency set-point reconfiguration problems in networked multi-area microgrid is presented. The aim is at finding a distributed coordination strategy able to reconfigure, whenever necessary in response to unexpected load changes and/or faults, the nominal setpoint on frequency and generated power to the generators of each area so that viable evolutions arise for the overall power system during transients and a new post-fault sustainable equilibrium is reached. In order to demonstrate the effectiveness of the strategy, an example on a four-area power system is presented. Copyright © 2014 John Wiley & Sons, Ltd.
