Research on the Charging Pile Construction and Load Acceptance Capacity of Distribution Network

With the development and improvement of the interactive operation mechanism of charging piles, the demand for the optimal configuration of electric vehicle charging stations and the construction of sufficient charging facilities is also increasing, and the ability of distribution network to accept charging piles is a direct reference for the planning and configuration of charging facilities. First, the profit function is constructed based on the statistical data of the influencing factors of cost and income, and the charging pile location model is established with the minimum return on investment as the objective function. And then realize the optimal construction location of electric vehicle charging pile by solving the model by dichotomy. Secondly, the number of charging piles is coupled with the charging load, and all kinds of operation risks caused by the charging load connected to the distribution network are comprehensively considered, and a model is established based on the standard of the number of charging piles that can be accepted by the distribution network. Finally, the charging load acceptance capacity of the distribution network is evaluated to ensure the safety of the distribution network operation. The example verification shows that the charging pile optimization location and the charging load acceptance capacity evaluation model of the distribution network are feasible and effective.
