Power Supply Capability Evaluation of Active Distribution Network with Charging-swapping-storage Integrated Station Based on Interval Theory

Aiming at the problems exited in power supply capability evaluation of active distribution network with charging-swapping-storage integrated station，a method for evaluating power supply capability of active distribution network with the charging-swapping-storage integrated station for electric vehicles based on interval theory is proposed. The interval theory is used to describe the uncertainty of electric vehicle arrival time， charging time and distributed generator output. Combined with the battery swapping rules and the charging/discharging strategy of the cascade energy storage system，the integrated station operation model is established. Based on the maximum load capability and heavy-loaded circuit ratio as indicators， the power supply capability evaluation model of active distribution network with the charging-swapping-storage integrated station is established，and the network reconstruction method and affine arithmetic are combined to solve the problem. The example verifies the effectiveness of the proposed method.
