电能期货合同市场的输电拥堵定价及其输电网的开放

该文提出了一个输电拥堵管理的新方法，这个方法能确保对所有的输电网使用者公平开放电网，并且对输电价格进行公平定价。首先，输电网使用者对使用区域电网之间的输电线路进行容量投标。然后，电网调度机构(ISO)按照输电网使用者对容量投标的价格来分配输电线路的可用容量，使得输电可用容量的总价值最大化。在一条拥堵的线路上得到输电容量调度计划的用户按照边际成本价格为使用这条线路输电而付费。在ISO为缓解区域之间的输电线路拥堵而调整输电计划时，它要对每个发电商和它们的相应用户之间的输电量分别进行平衡。通过将每对发电商，用户组合的输电业务量分离出来，ISO就可以只组织管理输电市场，而不介入发电商和用户之间双边合同形式的电能交易。

CONGESTION PRICING AND TRANSMISSION ACCESS IN THE ELECTRICITY FUTURES MARKETS

In this paper we present a new method of transmission congestion management. With this method, we can provide impartial access and prices to all users of the transmission system. The users bid for capacity on major transmission paths between zones. The Independent System Operator (ISO) dispatchs the usable transmission capacity on these paths so that it maximizes the value of the capacity by the users' bids. The users are charged the marginal-cost-based price for using a congested path. The ISO keeps each user's portfolio of generation and load individually in balance when adjusting schedules to relieve congestion on interzonal paths. By keeping the portfolios of the different parties separate, the ISO clears its transmission market without arranging energy trades between parties.
