Control Strategy for Virtual-inertial Power Compensation Considering Adjustable Potential of Charging Station
针对微电网因可再生能源接入导致惯量不足问题,提出了一种协同可再生能源发电的充电站惯性功率控制策略.首先,考虑到电动汽车具有良好的柔性调控潜力,在充电站层面将其等效为广义储能为控制器提供功率响应能力.接着,借鉴虚拟同步机的转子运行特性,提出了虚拟惯性功率补偿控制策略,并配合可再生能源发电提供频率支撑.最后,在MATLAB/Simulink中搭建了相应的仿真模型进行验证.仿真结果表明,所提出的虚拟惯性功率补偿控制策略能有效利用充电站调控潜力向系统提供惯性支撑功率,提高系统的频率稳定性.
To address the problem of inertia insufficiency in microgrids due to the integration of renewable energy sources,an inertial power control strategy for charging stations in collaboration with renewable energy generation is proposed.First,considering that electric vehicles(EVs)have good flexible regulation potential,they are treated as the generalized energy storage at the charging station level to provide power response capability for the controller.Then,the control strategy of virtual-inertial power compensation is proposed in reference to the rotor operation characteristics of virtual synchronous generator(VSG),which can cooperate with renewable energy generation to provide frequency support.Finally,the corresponding simulation model is built on MATLAB/Simulink for verification.The simulation results show that the proposed control strategy of virtual-inertial power compensation can effectively make use of the regulation potential of charging stations to provide inertia support power to the system,so as to improve the frequency stability of the system.
