摘要:
 针对新能源发电机组较多的区域电网在外送通道关闭的情况下易出现新能源消纳问题,提出一套基于仿射型区间潮流算法的电网新能源消纳指标,首先将区域电网发电侧,负荷侧转换为数学模型,发电侧结合仿射型区间潮流算法预测区域新能源出力上下限区间,引入 “区域电网新能源密度τt”“区域电网新能源消纳水平ζ”,“区域电网新能源越界时间T”。预测区域电网新能源消纳能力不足的容量及概率,并研究抽水蓄能调度缓解电网消纳压力的可行性。将水电站运行方式改为抽水蓄能后其问题得到明显缓解。仿射区间潮流算法对电网消纳指标的分析可为电网提供直观参考及调度策略。
Abstract:
 Regional power grids with more new energy generating units are prone to new energy consumption problems when the transmission channel is closed. The randomness of the power injected into the grid by new energy is strong, and the power flow distribution also changes accordingly. Interval power flow calculation can analyze such problems. This paper proposes a set of regional power grid new energy consumption indicators based on the affine interval power flow algorithm. Firstly, the power generation side and load side of the regional power grid are transformed into a mathematical model, and the power generation side is combined with the affine interval power flow algorithm to predict the upper and lower limits of the regional new energy output. “Regional power grid new energy density”, “regional power grid new energy consumption level”, and “regional power grid new energy cross border time”are introduced. It is to predict the capacity and probability of insufficient new energy consumption capacity of regional power grid, and to study the feasibility of alleviating the pressure of grid absorption. Finally the feasibility of the method proposed in this paper is verified through simulation and comparison of the calculation of the absorption index.
