风电和火电接入电网后的风电打捆控制方法
摘要：
本发明公开了电力系统安全防御技术领域中的一种风电和火电接入电网后的风电打捆控制方法。包括：正向或者逆向调整风电和火电的出力；分别计算调整风电和火电的出力后的电网暂态稳定裕度、元件负载程度指标和母线电压越限指标；根据调整风电和火电的出力后的电网暂态稳定裕度、元件负载程度指标和母线电压越限指标计算风电/火电付出值；当风电/火电付出值大于设定阈值，则逆向/正向调整风电和火电的出力；当风电/火电付出值小于设定阈值，则正向/逆向调整风电和火电的出力。本发明提供的风电和火电接入电网后的风电打捆控制方法，确保了风电和火电的合理出力，保障了电网的正常运行。
摘要（英）：

The invention discloses a wind power bundling control method after wind power and thermal power accessing to a power grid and belongs to the technical field of power system security defense. The method includes: forwardly or reversely adjusting wind power and thermal power output; respectively calculating and power grid transient stability margin, element load degree index and bus voltage threshold-crossing index after wind power and thermal power output adjustment; calculating wind power/thermal power output according to the calculated power grid transient stability margin, element load degree index and bus voltage threshold-crossing index; reversely/forwardly adjusting wind power and thermal power output when wind power/thermal power output is larger than a preset threshold; and forwardly/reversely adjusting wind power and thermal power output when wind power/thermal power output is smaller than the preset threshold. By the method, reasonable wind power and thermal power output is guaranteed, and normal operation of the power grid is guaranteed.
