| 摘要: |
| 换电模式因具有方便统一管理和利于快捷出行的特点，成为电动汽车不可或缺的一种能源供给模式，充分发挥换电模式的优势进行有序充电对换电站的发展具有重要的意义。在采用K最邻近算法对考虑变量间存在耦合关系的出行数据进行拟合的基础上，建立以电池间的状态转移关系为主要约束条件，以换电站的运营净利润为优化目标的模块分割式换电站有序充电模型，最后采用CPLEX求解器对该混合整数规划问题进行求解，并结合不同的电价策略加以分析。算例结果表明，在不同的电价策略下，相较于整车式换电站，模块分割式换电站在提高运营净利润方面具有明显的优势，且合理的电价策略能更加充分地发挥换电站的削峰填谷作用。 |

| Abstract: |
| The battery-swapping mode is an indispensable energy supply mode for electric vehicles due to its advantages of convenient and unified management and quick traveling. It is of great significance for the development of swapping stations to give full play to the advantages of battery-swapping mode for ordered charging. The KNN(K Nearest Neighbor) algorithm is used to fit the travel data considering the coupling relationship among variables. On this basis, the ordered charging model of swapping station based on modular split batteries is established with the state transition relationship among batteries as the main constraint and the station operation net profit as the optimization objective. CPLEX solver is used to solve this mixed integer programming problem, and different electricity price strategies are analyzed. The example results show that, compared with the whole-vehicle swapping station, the modular split batteries-based swapping station has an obvious advantage in improving the operation net profit under different electricity price strategies, and the reasonable electricity price strategy can give full play to peak-load shifting effect of the swapping station. |
