基于潮流贡献率的联营市场阻塞成本分摊方法
|
摘要
联营电力市场中出现阻塞时,考虑网络约束的统一出清价格将高于不考虑网络约束的统一出清价格,造成电网公司购电成本增加,由此产生阻塞成本。合理分摊阻塞成本是保证电网企业经营效益、确保电力市场有序运行的关键要素。为此首先引入了潮流贡献率指标,提出了联营电力市场统一出清模式下阻塞成本分摊的基本原则,进而设计了基于潮流贡献率的联营市场阻塞成本分摊方法,最后基于IEEE-30节点的算例验证了所提方法的有效性。
The unified clearing price is higher considering the network constraints in power pool market,which increases the power cost of power grid company and causes the congestion cost. Allocation of the congestion cost is a key factor to ensure the operation efficiency of power grid company and the orderly operation of power market. This paper firstly introduced the power flow contribution index,and then the basic principle of congestion cost allocation in the unified clearing mode of the power pool market was proposed and the congestion cost allocation based on power flow contribution index was designed. At last the validity of the method was proved based on an IEEE-30 buses system case.
