摘　　要：为提升新型电力系统的频率稳定性、直观指导新能源或储能场站的控制参数的设计,提出基于频率响应模型的主动支撑型电源的虚拟惯量与有功-频率下垂系数可行域分析方法。在满足系统频率稳定约束下,详细计及主动支撑型电源功率与能量约束以及联络线功率约束,利用遍历法获得主动支撑型电源虚拟惯量与有功-频率下垂系数可行域。通过在PSCAD/EMTDC中搭建风电场接入标准IEEE 39节点系统与四机两区域系统算例,验证了所提方法的有效性。To improve the frequency stability of a novel power system and guide the design of control parameters of renewable energy sources or energy storage stations intuitively,a feasible region analysis method for the virtual inertia and power-frequency droop gain of active-supporting sources is proposed based on the frequency response model.On the premise of satisfying the constraint of system frequency stability,the power and energy constraints of active-supporting sources and the constraints of tie line power are taken into account in detail,and the feasible region of the virtual inertia and power-frequency droop gain of active-supporting sources is obtained using the ergodic method.A standard IEEE 39-bus test system and a four-machine two-area test system are modeled in PSCAD/EMTDC to verify the effectiveness of the proposed method.
