考虑风电波动与电动汽车集群储能平抑控制策略
Considering the wind power fluctuation and the control strategy of energy storage and control of electric vehicle cluster
To promote the absorption of wind power in the power grid and reduce the load pressure of the distribution network, a control strategy considering the fluctuation of wind power output and the stabilization of the electric vehicle cluster energy storage system is proposed. Firstly, the energy storage modeling of the behavior characteristics of the single electric vehicle after entering the network is carried out. According to the active response ability of the electric vehicle under different SOC, the energy storage model of the electric vehicle cluster is constructed. Based on the difference of the energy storage ability of the cluster, multiple electric vehicle clusters are used to coordinate and suppress the power fluctuation of the tie line. Secondly, the cluster energy storage system makes the adaptive power distribution layer by layer according to the tie line power smoothing fluctuation value, determines the task power of each EV battery super capacitor, and makes full use of the continuous regulation ability of the vehicle network. The proposed strategy can reduce the load fluctuation in the distribution network after the large-scale electric vehicle connected, realize the mutual flow of power in the energy storage system, and effectively reduce the allocation of conventional energy storage capacity.
