为解决风力发电、光伏发电等分布式电源出力波动和大规模负荷入网造成的频率波动问题,电动汽车在(The electric car)热备用条件下基于V2G技术,以电动汽车作为调频手段,研究电动汽车负荷聚类参与电网一次调频控制策略。根据电动汽车快速响应性能对电动汽车负荷聚类,采用聚类算法将电动汽车负荷分组对不同调频容量分配。当系统频率发生变化时,以实现电动汽车参与电网一次调频响应。仿真结果表明：当电网频率波动时,电动汽车参与电网一次调频,使得电网频率能够很快向稳定状态恢复。本文所提电动汽车负荷聚类参与调频控制策略是有效的。
In order to solve The frequency fluctuation caused by The output fluctuation of distributed power sources such as wind power generation and photovoltaic power generation and The large-scale load entering into The grid, The primary frequency modulation control strategy of ev load clustering in The power grid was studied based on The V2G technology under The hot standby condition of The Electric car. The load of electric vehicles was classified according to the quick response performance of electric vehicles, and the load of electric vehicles was divided into different frequency modulation capacities by clustering algorithm. When the system frequency changes, the electric vehicle participates in the primary frequency modulation response of the power grid. The simulation results show that when the frequency of the power grid fluctuates, the electric vehicle participates in the primary frequency modulation of the power grid, which makes the power grid frequency quickly recover to a stable state. The proposed ev load clustering strategy is effective in frequency modulation control.
