适应于光伏接入与商圈通勤需求的电动汽车充换电能量管理策略

Energy Management Strategy for Electric Vehicle Considering Photovoltaic Power Consumption and Commuter Demand

光伏功率的消纳问题限制了光伏电源在城市的推广和应用进程。"光-储-车"一体化建设为光伏在城市的应用提供了一种合理的解决手段。随着电动汽车(electric vehicle,EV)数量增长,城市商圈成为电动汽车充电和停车的热点地区。文章提出了一种适应于光伏接入与电动汽车充换电需求的商圈综合体结构,该综合体包括地上换电区、地下快充区和地下停车场式慢充区。同时,为解决商圈综合体的能量管理问题,提出了一种基于多代理模型的能量管理方法。最后,通过一天96个调度时刻的仿真算例验证了商圈结构的可行性及能量管理策略的合理性。该能量管理策略在满足供需平衡及电动汽车充电约束的基础上,实现了慢充区充电负荷的合理平移、光伏功率的灵活消纳以及各区域能量的有效管理,降低了商圈电动汽车的充电成本。

The fluctuation of photovoltaic power limits the promotion and application of photovoltaic power in cities.The integrated construction of photovoltaic-storage-vehicle provides a reasonable solution for the application of photovoltaic pow er in cities. With the increase of electric vehicles( EVs),business district has become a hot spot of electric vehicle charging and parking. Considering photovoltaic pow er consumption and commuter demand,a new construction of business district is proposed in this paper,including exchange area,fast charge area and slow charge area. Moreover,on the basis of multi-agent model,a management strategy for electric vehicle energy is proposed. The feasibility of the commercial district structure and the rationality of the energy management strategy are verified in the simulation of 96 scheduling times.Considering constraints of pow er balance and electric vehicles,the energy management strategy realizes the reasonable translation of charging pow er in the slow charge area,the flexible absorption of photovoltaic pow er and the effective management of electricity energy in each area. The total costs of electric vehicles are decreased in business district.
