Pseudo-decentralized control-communication optimization framework for microgrid: A case illustration

Abstract

We describe a joint wireless communication network (WCN) and power network (PN) optimization framework for implementing a pseudo-decentralized control of a distributed generation network. The optimization framework includes two coupled blocks: one whose focus is on ensuring that the PN operates within its stability and performance bounds and the other, whose thrust is on optimization of information flow of a WCN from a dynamic network capacity standpoint. We have outlined a control architecture that can be used to implement the joint optimization scheme in a distributed manner using a global supervisory controller (GSC) and local controllers with some intelligence. We describe mechanisms for sustaining optimal performance in the presence of link disruptions. Extensive simulations are performed to verify the effectiveness of the proposed framework.
