【摘要】：微电网中包含可再生能源和电动汽车等不确定性电源和负载,不利于微电网的稳定运行。基于风光储的微电网系统,考虑电动汽车的时空分布特性,提出一种动态电价调整策略。根据可再生能源出力和负荷的实时数据,求出当前微电网中的不平衡功率,根据当前不平衡率(UR),发布对应的电价信息,充分调动电动汽车参与微电网的调度,实现微电网中可再生能源和电动汽车间的协调控制。最后通过搭建微电网仿真模型对所提动态电价调整策略进行验证,通过对比电动汽车无序充电和有序充放电情况下微电网的等效负荷以及储能运行情况,来验证该策略在微电网运行优化方面的有效性。
[Abstract]:Microgrid contains uncertain power supply and load, such as renewable energy and electric vehicle, which is not conducive to the stable operation of microgrid. Based on the microgrid system of scenery storage and considering the temporal and spatial distribution characteristics of electric vehicles, a dynamic electricity price adjustment strategy is proposed. According to the real-time data of renewable energy output and load, the unbalanced power in the current micro-grid is obtained, and the corresponding electricity price information is released according to the current imbalance rate (UR),. The electric vehicle is fully mobilized to participate in the dispatching of the micro-grid, and the coordinated control between the renewable energy and the electric vehicle in the micro-grid is realized. Finally, the dynamic electricity price adjustment strategy is verified by building a microgrid simulation model, and the effectiveness of the strategy in microgrid operation optimization is verified by comparing the equivalent load and energy storage operation of the microgrid under the condition of disorderly charging and orderly charging and discharging of electric vehicles.
