| 摘要: |
| 风电出力对电力系统运行的影响存在复杂的非线性，现有处理风电随机性的风电场景模型难以保证风电场景与电力系统优化运行保持一致，为此提出含多风电场的电力系统无功/电压灵敏度场景分析方法。首先利用网损/电压灵敏度计算方法计算多风电场相关性出力样本的网损/电压灵敏度，再基于主成分分析构建联合网损/电压灵敏度特征空间，并在此基础上进行场景聚类，得到多风电场网损/电压灵敏度场景。将某2个风电场的实际数据接入IEEE 30节点系统中分别进行传统风电场景分析和所提灵敏度场景分析，验证了所提方法的有效性和优越性。 |

| Abstract: |
| There exists complex nonlinear impact of wind power on power system operation, and the traditional wind power scenario model for dealing with the randomness of wind power cannot ensure the consistency of optimal operation of power system and wind power scenario, for which, an analytical method of reactive power/voltage sensitivity scenario for power system with multiple wind farms is proposed. The power loss/voltage sensitivity calculation methods are adopted to calculate the power loss/voltage sensitivities for the correlated output samples of multiple wind farms, the principle component analysis is used to build the combined power loss/voltage sensitivity feature space, on this basis, the power loss/voltage sensitivity scenarios of multiple wind farms are obtained by scenario clustering. The practical data of two wind farms are connected into IEEE 30-bus system for the traditional wind power scenario analysis and the proposed sensitivity scenario analysis, the simulative results verify the effectiveness and superiority of the proposed method. |
