the proportion of intermittent new energy access continues to increase
which not only brings challenges to the security and stability of the power grid
but also leads to different degrees of abandonment of wind and solar energy everywhere. To this end
a two-stage distributed energy consumption strategy for active distribution networks taking into account electric vehicles is proposed. In the previous stage
considering the mutual complementarity of electrical energy between adjacent areas of the distribution network
taking into account their own interests while maximizing the consumption of new energy
the alternating direction multiplier method(ADMM) is adopted to carry out distributed solutions to reduce the computational pressure. Considering the prediction deviation in the intraday stage
the model prediction control method is employed to guide the electric vehicle and energy storage system to respond quickly
thus to realize the intraday new energy consumption by adjusting the power of the contact line in the adjacent area
and track the scheduling plan before the day. Through the example analysis
the proposed two-stage new energy consumption strategy can effectively coordinate the energy distribution problem between regions and promote the consumption of excess energy.
