基于典型场景划分的多时段网损分摊算法

网损分摊是电力市场中的重要问题。传统的网损分摊算法研究往往针对单一时间断面下的静态分摊问题,不能满足实际系统连续运行分析计算的要求。为此,基于潮流跟踪算法,选取关键线损线路和强相关电厂两项指标,提出了相似网损分摊场景匹配标准。在此基础上,考虑实际运行需求提出了基于典型场景划分的多时段网损分摊算法,以解决多时段连续运行中的网损分摊问题;最后基于我国某省电网实际数据构造算例,验证了本方法的有效性。

Multi-Period Power Network Loss Allocation Algorithm Based on Typical Scene Division

Power network loss allocation is an important issue in power market.The traditional power network loss allocation algorithm focuses the static allocation problem in a single period,which can't meet the requirements of continuous operation analysis in the actual power market.To this end,this paper selects two indexes,namely key network-loss transmission line and strong relevant power plant based on power flow tracking algorithm,and proposes a matching criteria of similar power network loss allocation scenes.According to this matching criteria,a multi-period power network loss allocation algorithm based on typical scene division is proposed to solve the problem of multi-period network loss allocation in a continuous operation power market.Finally,the effectiveness of the proposed method is proved by a case study based on the actual data of a province in China.
