摘要(Abstract)：

空间电力负荷预测(spatial load forecasting,SLF)是城市电网规划必不可少的计算,其预测结果是确定所需配置供电设备容量和分布的基础,预测结果准确与否对城市电网建设及其运行的经济性和安全性都有影响。文章从城市电网的空间结构分析入手,以分层分区处理为原则,以目标层级的负荷元胞为基础,描述和刻画了该层级下空间电力负荷的规律性,着重分析了10 kV电压层级下元胞负荷的周期性、增长的非平稳性及元胞之间的负荷转移。通过实例进一步阐述了该负荷规律性分析方法,结果表明该方法能够充分合理地描述空间电力负荷的特点,客观反映SLF方法的优劣,为寻找更有效的SLF方法奠定了基础。
