A Modular Generic Microgrid Controller Adaptive to Different Compositions

In this paper, a modular generic microgrid controller adaptive to different compositions and applications is presented. The rule-based dispatch strategy is designed to maintain power balance, follow the power reference at the point of interconnection, while reducing renewable generation curtailment and load shedding. The main feature of the controller is the modular architecture and the adaptivity to the removal or addition of assets. When assets are removed from microgrids, the dispatch strategy can adapt to this variation by setting their power constraints as zero. When more assets of the same type are added, they can be aggregated as one group and managed with a weighted and queuing algorithm to distribute power among the group members.
