【摘要】：通过引入电动汽车换电站的有序充电策略,以系统建设运行成本、综合净负荷波动指标以及网络能量损耗最小为目标,提出统筹考虑电动汽车换电站和分布式电源的多场景协调规划方法,并给出满足电动汽车换电需求约束和备用电池存在性约束的备用电池调度方案和最少备用电池计算方法。结合风光电源出力的季节特性,针对IEEE 33节点系统,利用生物地理优化算法进行多场景规划仿真分析,验证了所提规划方法可利用换电站有序充电策略平抑配电网综合净负荷波动,起到了削峰填谷的作用,大幅降低了网络能量损耗,显著提高了风光电源的可规划容量;同时所采用的最少备用电池计算方法,可充分考虑换电站内备用电池在一天中的循环利用,在维持有序充电策略周转的前提下能有效缓解电池储备压力,大幅降低了换电站投资成本。
[Abstract]:By introducing the orderly charging strategy of the electric vehicle power station, the aim is the operation cost of the system construction, the comprehensive net load fluctuation index and the minimum energy loss of the network. A multi-scene coordinated planning method considering electric vehicle power station and distributed power generation is proposed. The scheduling scheme of reserve battery and the calculation method of least spare battery are given, which can meet the demand constraint of electric vehicle power exchange and the existence constraint of backup battery, combined with the seasonal characteristics of wind power output. For IEEE 33-bus system, biogeographic optimization algorithm is used to simulate the multi-scene planning, and it is verified that the proposed planning method can be used to stabilize the comprehensive net load fluctuation of distribution network by using the orderly charging strategy of power station. It can cut the peak and fill the valley, reduce the energy loss of the network, and increase the programmable capacity of the wind power supply. At the same time, the minimum standby battery calculation method can fully consider the recycling of the reserve battery in the power station in one day, and can effectively alleviate the battery reserve pressure under the premise of maintaining the orderly charging strategy turnover. Greatly reduced the investment cost of power station exchange.
