在库联营基础上开放双边交易有重要的市场意义 ,然而其过网服务定价却是一个复杂问题。文中论述了过网费中应包括的 6项主要成分 ,即输电线路运行和投资的 2项回收成本 ,网络阻塞和优化调度的 2项机会成本 ,以及运行备用和自动发电控制 (AGC)的 2项辅助服务成本 ,这 2项辅助服务都是交易中心购自库联营发电并通过输电网提供的。前 4项基本的回收成本和机会成本都已在输电当量电价中计入 ,而AGC辅助服务适合另行单独定价和考核。文中主要介绍了包含运行备用辅助服务的双边交易过网服务的当量电价方法。算例给出了不含和含运行备用的过网电价的日变化曲线及其成分 ,表明在过网电价中自动包含运行备用辅助服务成本是必要的、可行的 ;还表明在过网主要路径附近存在阻塞时 ,过网费率灵敏于负荷水平和过网节点 ,从而展现了当量电价方法解决这类复杂问题的优越性。
The opening up of bilateral transactions on the basis of the pool association has important market significance. However, the pricing of its network service is a complex issue. This paper discusses the six main components to be included in the overlay fee, namely, two recovery costs of transmission line operation and investment, two opportunistic costs of network congestion and optimal dispatch, and 2 Auxiliary service costs, these two ancillary services are purchased from the library trading center power generation and transmission through the transmission network. The first four basic recovery costs and opportunity costs have been included in the transmission-equivalent electricity price, while the AGC ancillary services are eligible for separate stand-alone pricing and assessment. This paper mainly introduces the equivalent electricity price method of bilateral trade network service that contains standby auxiliary service. The example gives the diurnal variation curve and its components of the grid-connected electricity price without and without backup, which shows that it is necessary and feasible to automatically include the cost of operating the backup auxiliary service in the grid-connected electricity price. It also shows that in the main route In the presence of congestion nearby, the net rate is sensitive to the load level and nodes in the network, thus demonstrating the superiority of the equivalent rate method to solve such complex problems.
