一种基于区域电网变负荷下接纳风电功率测算方法
摘要：
本发明公开了一种基于区域电网变负荷下接纳风电功率测算方法，解决了现有的区域电网接纳风电功率测算不合理、可信度差的技术问题。先确定区域电网的最小开机方式，计算出该方式下区域电网的高峰负荷与区域电网的风电接纳功率，然后基于区域电网的最小开机方式，计算出风电接纳功率为0时对应的区域电网的高峰负荷，再然后基于区域电网最大开机方式，计算出该方式下区域电网的高峰负荷与区域电网的风电接纳功率，最后建立直角坐标系，横坐标为区域电网的高峰负荷，纵坐标为风电接纳功率，绘制出基于区域电网负荷变化情况下风电接纳功率曲线。减轻了调度运行人员的运行压力，强力保障了电网的安全稳定运行。
摘要（英）：

The invention discloses a wind power acceptance power measurement method based on a variable load of a regional power grid and aims at solving the technical problems that existing wind power acceptance power measurement of the regional power grid is unreasonable and poor in reliability. The method comprises the following steps of firstly determining a minimum startup mode of the regional power grid, calculating a peak load of the regional power grid and wind power acceptance power of the regional power grid in the mode and then calculating corresponding peak load of the regional power grid when the wind power acceptance power is zero based on the minimum startup mode of the regional power grid; calculating the peak load of the regional power grid and the wind power acceptance power of the regional power grid in the mode based on a maximum startup mode of the regional power grid; and finally building a right-angle coordinate system, wherein a horizontal ordinate is the peak load of the regional power grid and a longitudinal coordinate is the wind power acceptance power, and drawing a wind power acceptance power curve based on the load change condition of the regional power grid. The operating pressure of dispatching operators is relieved and safe and stable operation of the power grid is powerfully guaranteed.
