Research on Capacity Optimization of Power Station for Electric Taxi Distribution Network

Due to some characteristics of power energy, electric vehicles cannot achieve instantaneous energy supplements at present. Although the rapid charging technology takes a short time, it still cannot fundamentally solve the contradiction between ‘endurance mileage’ and ‘battery capacity’. At present, China State Grid and Southern Power Grid Corporation put forward the operation mode of electric vehicle charging and switching power stations. Taxi is an important part of urban public transport. In the construction and operation of electric taxi switching power stations, although a certain number of switching power stations are put into use, the research on the optimal capacity optimization planning of electric taxi switching power stations is still scarce, and thus the rational allocation of resources cannot be achieved in the construction and operation of distribution network switching power station. In order to solve this problem, this paper studies the capacity optimization of electric taxi switching stations by constructing a comprehensive cost model of switching stations. The main approach is to study the optimal battery capacity of the swapping station under the condition of different scales of service for electricity swapping and leasing, taking the maximum return of the swapping station as the optimization objective, taking into account the fixed investment cost and battery purchase cost in the construction and operation of the swapping station, and taking the price as the constraint condition.
