With the development of renewable energy generation technology and electric vehicles, photovoltaic charging stations are expected to become the mainstream charging facilities for electric vehicles in the future. However, their output uncertainty and source-load fuzzy characteristics pose new challenges to the optimal dispatching of distribution networks. This paper proposes an optimal dispatching strategy for an active distribution network considering the dispatchable capacity of photovoltaic charging stations. First, the dispatchable capacity of energy storage systems and electric vehicles is analyzed; then, a dispatchable capacity model of photovoltaic charging stations is constructed; then, with the lowest operating cost of the active distribution network as the optimization goal, an optimal dispatching model of the active distribution network considering the adjustable capacity of photovoltaic charging stations is established, and the second-order cone programming algorithm is used to solve it. Finally, the proposed method is verified by an IEEE33 node example. The results show that the proposed strategy can effectively reduce the operating cost of the distribution network.
