Distributed energy collaborative control strategy for grid-connected electric vehicles

The coordinated regulation of large-scale electric vehicles (EV) and distributed clean energy is a powerful means to ensure the optimal economic operation of the power grid. Firstly, considering the differentiated needs of EV users, the general model of EV load is expanded; secondly, considering the participation of EV aggregators, the EVs under the jurisdiction of each aggregator are divided into a cluster; and then the distribution network operator (DNO) is proposed. ) and EV Aggregator (EVA) collaborative optimization model; the alternating direction multiplier (ADMM) algorithm is introduced to solve the model, and the DNO optimization and EVA optimization are decoupled to realize the distributed solution of the model. Finally, the superiority of the model is verified by adopting the IEEE33 node distribution network.
