Abstract

The rapid development of electric buses has brought a surge in the number of bus hubs and their charging and discharging capacities. Therefore, the location and construction scale of bus hubs will greatly affect the operation costs and benefits of an urban distribution network in the future. Through the scientific and reasonable planning of public transport hubs on the premise of meeting the needs of basic public transport services, it can reduce the negative impact of electric bus charging loads upon the power grids. Furthermore, it can use its flexible operation characteristics to provide flexible support for the distribution network. In this paper, taking the impact of public transport hub on the reliability of distribution network as the starting point, a three-level programming optimization model based on the value and economy of distribution network load loss is proposed. Through the upper model, several planning schemes can be generated, which provides boundary conditions for the expansion of middle-level optimization. The normal operation dispatching scheme of public transport hub obtained from the middle-level optimization results provides boundary conditions for the development of lower level optimization. Through the lower level optimization, the expected load loss of the whole distribution system including bus hub under the planning scheme given by the upper level can be obtained. The effectiveness of the model is verified by an IEEE-33 bus example.
