摘要: 针对配电网网格化分层负荷预测横向收集数据繁杂、可操作性低等问题,设计无后效性的贪婪算法。该算法采用自顶而下的人机合作方式进行贪婪选择,使用土地综合分类法重新划分用地类型,确定最佳分配因子,从而简化数据处理过程。为解决负荷级别的区域划分,建立结合贪婪法与网格法的空间负荷预测平台。通过对水平年用地规划图进行阈值分割,并结合变电站供电情况,实现利用灰度图直观展现供电情况,并由此提出基于供电区域划分的配电网规划方法。分析结果表明,所提方法保障了配电网的稳定运行,并且对水平年的配电网规划有重要的指导作用。

Abstract: In view of complicated data collecting and low operability of power grid load forecasting,a greedy algorithm of no aftereffect is proposed in this paper.In the greedy algorithm,top-down man-machine cooperation is used to select and criticize the greed to select data.And then,integrated land classification is used to re-divide land type and determine the optimal allocation factor,thereby simplifying the data processing process.Afterwards,the spatial load forecasting platform combining the greedy and grid algorithms is established to divide the load level.The power supply situation can be intuitively displayed using the grayscale map through the threshold segmentation of the land-use planning diagram combined with the substation power supply situation.The network planning method is proposed based on power supply zone.Analysis result shows that the proposed method guarantees the stable operation of distribution network,and plays an important role in guiding power grid planning.

Key words: grid load forecasting, optimal allocation factor, greedy algorithm, spatial load forecasting platform, typical power supply mode
