Abstract


  • This paper describes a combined current and voltage unbalance compensation scheme for static power converters on a multi-bus microgrid utilizing cooperative regulation on a sparse ad-hoc communication network. The proposed control scheme is both robust to changing network conditions and corrects for sub-optimal gain settings at each distributed generation unit. The scheme is based on local voltage and current measurements by each distributed generation unit on the network, and utilizes a primary and secondary control hierarchy. The scheme is then simulated using Matlab SimPowerSystem to demonstrate operation of the compensation scheme and evaluate its performance.
