基于实时电价的多目标电动汽车控制策略

在实时电价的电力市场机制下,综合考虑了电网侧和电动汽车车主双方利益,建立了电动汽车群接入电网后的控制模型.该模型以电动汽车群接入电网后负荷曲线峰谷差最小及电动汽车车主收益最大为优化目标,并以电池充放电功率和可用容量为约束条件,采用粒子群算法进行了优化求解,得出了电动汽车群与电网的交互功率曲线.最后,通过仿真实例验证了所建构模型的正确性和有效性.

Research on Multi-target Control Strategy of EVs Based on Real-time Price

A mathematical model is developed on the basis of adopting real-time price in the electricity market and taking into consideration both the profit of power grid and the profit of owners of EVs.The targets of optimization are to minimize the peak-valley difference of power load and maximize the profit of consumer for the participation of EVs in the constraints of battery power and capacity,and solve it by the Particle Swarm Optimization(PSO),and then obtain the power curve between electric vehicles and power grid.Finally,the feasibility and efficiency of the proposed model are verified with the simulation of a given example.
