国外典型电网负荷特性分析

Research of the load characteristics of typical areas in overseas

负荷特性分析是电力系统运行管理中的一个重要环节,掌握电力负荷特性的变化规律和发展趋势是建立负荷预测模型的基础。在参考相关文献的基础上,建立了较为完善的负荷特性指标体系,并收集了日本东京、美国东北部电网、纽约电网等多个地区电网的负荷数据,对上述地区的负荷特性曲线进行了深入分析,以期为我国电网的负荷特性研究提供参考。

The analysis of the load characteristics is an important part of electric power system operation, and that having a good command of the law of the load characteristics changing and develop ing is the key to establish the forecast model. Therefore, a complete index system of load characteristics is established in this paper on the basis of reading amount of document, And then the load characteristic of some typical areas such as Tokyo, PJM, NYISO and so on was pursued to find out the change rule of the load characteristics in these typical areas. A few useful conclusions could he drawn to provide inspiration for the load analysis of our provincial grid.
