摘　　要：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。Opening bilateral transaction markets on the basis of the Pool ones has the great significance to the electricity markets, however it brings a complex wheeling pricing problem. It's argued in this paper that there are mainly six components for a wheeling price: the operation and investment costs to be returned, the opportunity costs came from congestion and re-dispatch, as well as the costs in Automatic generating control (AGC) and operating reserves. The last two are chief ancillary services bought from the Pool generators then supplied to the bilateral traders through the transmission grid. This paper presents the models and algorithms of wheeling pricing with operation reserve ancillary service for bilateral transaction using EVE methods. A case study shows that the wheeling prices are sensitive to the system load level and the wheeling buses when congestion exists around the main paths of the bilateral transactions.
