电池交换站与微电网基于影子价格的协调优化

电池交换站(battery swap station，BSS)的发展可有效缓解电动汽车行驶里程有限、充电时间长所带来的问题。首先提出微电网、BSS 2个独立非合作实体管理系统日前经济运行的新型优化模型；然后设计一个以市场为基础的机制，使2个系统能够有效地协调，该协调机制只需要在2个实体之间交换单个影子价格和充放电功率请求；最后采用CPLEX软件与改进的风驱动优化算法，得到微电网和BSS的充放电功率和影子价格，对所提出的模型进行求解。通过数值算例验证该方法的有效性和可扩展性，并由改进的IEEE 33总线系统算例验证了所提优化模型的合理性和有效性。

Coordination and Optimization of Battery Swap Station and Microgrid Based on Shadow Price

The development of the battery swap station (BSS) can effectively alleviate the troubles due to limited road haul and long charging time of the electric vehicle. Firstly, a new optimization model for day-ahead economic operation of two independent non-cooperative entity management systems, i.e., the microgrid and BSS, was proposed. Then, a market based mechanism that could make the two systems coordinated effectively was developed, and the coordinated mechanism only needed to exchange the single shadow price and the request of charge-discharge power between two entities. Finally, the software CPLEX and the improved Wind Drive Optimization Algorithm (WDO) were utilized to obtain the charge-discharge power and the shadow price of microgrid and BSS to solve the proposed model. Results of calculation example show that the proposed method is effective and extensible, and the rationality and effectiveness are validated by the simulation results from the improved IEEE 33-bus system.
