Dynamic Average Consensus Based Control Scheme in Community Microgrid

Abstract

Microgrid addresses the solution for many real time complications of centralized grid operation. The gap between the centralized and smart grid paradigm can be filled with the help of smartly operating microgrid systems. The challenges faced in centralized control can be addressed by distributed control techniques. The hierarchical control strategies are widely adopted for reliable operation of microgrid systems. The three control layers adopt different techniques to meet the voltage and frequency regulation along with power sharing concerns. The secondary layer can adopt dynamic average consensus algorithm for exchanging the data to immediate neighbor unit with limited communication requirement. The algorithm achieves the aim of centralized controller in a distributed manner. This paper provides review on the dynamic average consensus based distributed control in microgrid operation.
