Abstract
This paper establishes a distributed optimization operation model of microgrid group to solve the problem of privacy security and economic conflict among different stakeholders. Firstly, the factors affecting the operation cost are analyzed from the perspective of the internal equipment and external active/reactive power transactions of the microgrid. Then, each node in the microgrid group takes the overall operating cost as the optimal objective, and particle swarm optimization (PSO) algorithm is used to optimize the model. Furthermore, the collaborative optimization algorithm is adopted to reach an agreement of the respective optimization results through the exchange of key information among different node agents, and the optimal dispatching strategy is obtained independently. Finally, the model is applied to the improved 30-node microgrid group system. The results show that the model and algorithm can reduce the operating cost of the microgrid group, ensure the maximum benefit of the individual subject, and achieve the optimal operation of the multi-microgrid system.
