研究了风电场参与调频对电力系统减振的影响。考虑了两种参与频率调节的方案：基于惯性响应的方案和基于功率储备的方案。利用15节点试验系统，对几种负荷条件和同步发电机惯性进行了小干扰稳定性分析。研究发现，风电机组通过备用电源参与频率调节的影响很小；实际应用中的特征值与不参与频率调节时的特征值相同。当风力发电机组通过惯性响应参与频率调节时，电力系统的阻尼发生了很大的变化，风力发电机组的位置起着重要的作用。对于所考虑的试验系统，当风电机组与发电机的连接距离越近，惯性越小时，电力系统的阻尼值增加最大。这些结果是有希望的，因为它们可以为规划目的带来有用的指标或规则。
The impact of the participation of wind farms in frequency regulation in power system damping is studied. Two schemes to participate in frequency regulation are considered, which are based on inertial response and power reserve. Using a 15-bus test system, a small-signal stability analysis is performed for several loading conditions and synchronous generators (SGs) inertia. The impact of WTGs participating through power reserve is found to be minimal; eigenvalues for practical purposes are the same than when WTGs do not participate in frequency regulation. When WTGs participate in frequency regulation through inertial response, the power system damping is considerably altered and the location of WTGs has an important role. For the considered test system, the largest increase in power system damping is obtained when WTGs are connected closer to the generator with less inertia. These results are promising as they can lead to useful metrics or rules for planning purposes.
