摘要：

To ensure proper action of protection and reduce the influence of disordered charging of EV(Electric Vehicle) and fluctuation of DER(Distributed Energy Resource), an optimal operating strategy is proposed. This strategy is based on the coordination of EV and DER considering current protection. To improve the efficiency of solution, the cluster control strategy is adopted in EVs. This model is built without changing the original protection schemes based on information fusion nodes. Standard deviation of load and cost of EV owners are considered as objectives. Combined explicit and implicit indexes of current protection with voltage indicators, the optimal scale of EV access to the distribution network is assessed. The optimal operating states can be obtained by the coordination of EV and DER on the optimal scale. To conform to reality better, the states are amended by model predictive control. The proposed strategy is proved to ensure benefit of owners and proper action of protection anytime during optimal cycle by case analysis in three scenarios. And the strategy is also proved to maintain voltage at normal range, stabilize load fluctua-tion, decrease load level and reduce network losses. © 2020, Electric Power Automation Equipment Press.
