地区电网新能源消纳困难时段研究

Research of SevereTime Period of New Energy Accommodation in Regional Power Grid

文章主要研究了某实际电网新能源消纳困难时段。通过负荷特性分析,得出地区电网低谷负荷出现季节和典型日负荷特性,通过风电场、光伏电站出力特性分析,得出风电、光伏季节分布特性及日出力特性。在地区电网新能源消纳的困难时段分析基础之上,对困难时段负荷概率进行统计,得出困难时段的负荷取值,为新能源接纳能力分析提供重要的数据支撑。

This paper mainly studies the severe periods of a power grid in its accommodation capacity of new energy.The load analysis reveals seasonal and typical daily characteristics of the valley load in regional power grid.The output power analysis of wind farms and photovoltaic power stations shows characteristics of seasonal distribution.Based on the above analyses,the load probability of the severe period is calculated to obtain the load value,which provides important data support for the analysis of new energy accommodation capacity.
