摘要
在多种交易模式(联营体交易,双边交易,多边交易)共存的电力市场中,如何公平合理地分摊对输电网的使用费是一个尚未很好解决的困难问题,作者提出了一种实用的方法。以直流潮流模型为基础,首先根据发电转移分配因子(GSDF)计算各个合同交易应该承担的输电网的使用费,然后分别用顺流跟踪法和逆流跟踪法将由此确定的每个交易应该承担的总的使用费分摊到参与该交易的各个发电公司和负荷。这就综合了GSDF方法和潮流跟踪方法的优点,概念清晰,计算速度快,并且可以应用于存在多种电力交易的电力市场,以及互联的多区域与分层电力市场。
In an electricity market coexisting with varied transaction modes such as pool transaction mode, bilateral transaction mode and multilateral transaction mode, it is a difficult and not well solved problem to allocate the transmission cost fair and equitably. Here a practical method is presented in which on the basis of the DC power flow model firstly the transmission cost that should be borne by each contract sale is calculated by Generation Shift Distribution Factor (GSDF), then with upstream tracing algorithm and downstream tracing algorithm separately the previously determined cost of each contract sale is further allocated to all of the generating companies and loads who take part in the transaction. Thus, the advantages of GSDF method are integrated with that of the tracing method, so the concept of this method is clear and by which the calculation is speedy. Besides, this method can be applied to the electricity market coexisting varied transactions as well as to the mutliple-regional and hierarchical electricity markets.
