一种计及风电功率预测误差的风电消纳评估方法
摘要：
本发明公开了一种计及风电功率预测误差的风电消纳评估方法，包括：步骤1，制定发电计划；步骤2，基于风电功率预测历史统计数据生成预测误差时间序列；步骤3，潮流计算，并判断电力系统是否满足约束条件；若满足约束条件，执行步骤5；否则，执行步骤4；步骤4，按预设步长减小风电场有功功率和/或电力系统总负荷，然后，继续潮流计算；步骤5，根据潮流计算结果评估风电消纳状况。本发明更详尽地描述风电功率预测误差的时间序列特性，能适用于较短的时间尺度，更符合电力系统的实际。
摘要（英）：

The invention discloses a wind power adsorption estimation method involving a wind power forecast error. The wind power adsorption estimation method comprises the following steps: (1) drawing a generation schedule; (2) predicting historical statistics data based on wind power so as to generate a prediction error time sequence; (3) carrying out load flow calculation, judging whether a power system meets constraint conditions, if so, carrying out a step (5), and if not, carrying out a step (4); (4) reducing the active power of a wind power plant and/or total load of the power system according to a preset step length, then further carrying out load flow calculation; and (5) estimating a wind power adsorption condition according to a load flow calculation result. According to the wind power adsorption estimation method, the property of the time sequence of the wind power prediction error is relatively detailedly described; the wind power adsorption estimation method can be applied to relatively short time scale and can relatively well meet practical conditions of the power system.
