随着电力市场化改革的逐步开展,输电阻塞和储能阻塞已成为影响电网安全经济运行的关键。为了最大化市场参与者的利益,解决电力市场环境下的输电阻塞和储能阻塞问题,提出了一种基于金融输电权和金融储能权混合拍卖的电力市场风险管理模型。在一级市场和二级市场分别构建了金融输电权和金融储能权的单边竞价和双边竞价拍卖机制,并采用效用函数表征了市场参与者的风险规避,通过权利市场5节点系统测试数据进行验证,详细分析了金融输电权和金融储能权拍卖市场给市场参与者利益带来的影响。仿真结果表明,所提出的风险管理模型能够有效降低输电阻塞和储能阻塞给市场参与者带来的风险。 相似文献

基于猜测价格函数的混合输电权竞价策略分析 总被引:1,自引:0,他引:1
作为市场参与者规避阻塞价格风险的工具,输电权已被成功应用于多个电力市场。文中基于猜测价格函数,提出了一种混合输电权竞价策略的分析方法。在所建模型中,竞标个体可以购买任意组合的义务型金融输电权(FTR)、期权型FTR和关口输电权(FGR),其策略性竞价行为则通过猜测价格函数进行模拟。将该模型的计算转化为求解一个凸二次规划问题,不仅保证了解的唯一性和存在性,还使得该方法能够用于大规模混合输电权市场中的竞价策略分析。通过算例验证了该方法的有效性。 相似文献

金融输电权和输电期权在输电阻塞管理中应用 总被引:6,自引:0,他引:6
在电力市场中,输电阻塞是影响电网安全运行的重要因素,也是影响市场电价水平的重要方面。如何消除由于阻塞带来的价格风险是输电阻塞管理研究的热点.分析了金融输电权FTR(Financial Transmission Right)规避阻塞风险的基本原理、特点和不足。在此基础上引入了输电期权T0(Transmission0ption)概念,它有效规避了由于阻塞给市场参与者带来的风险,并且克服了金融输电权反向潮流的缺点,对于输电期权的特点进行了实例说明.并且与金融输电权进行了比较分析。最后,指出输电期权为输电阻塞管理提供了一个可行的研究方向。 相似文献

在输电网开放的电力市场环境下,利用金融输电权(FTR)进行阻塞管理是近年来阻塞管理领域的研究热点,而拍卖是进行FTR分配的主要方式之一。采用FTR对冲阻塞风险,将FTR拍卖市场和电能交易市场相结合,提出了考虑阻塞风险的供电公司双层最优购电组合模型,上层优化以供电公司效用最大化为目标,下层以FTR拍卖收益最大化为目标。在决策过程中综合考虑了电能市场和FTR拍卖市场的双重不确定因素。针对该双层优化模型的随机性特点设计了基于蒙特卡罗和微分进化的双层微分进化(BDE)算法。算例结果证明了适当的FTR可降低购电组合的风险,并表明了该双层模型和算法的合理性和有效性。 相似文献

一种改进型金融输电权与基金池相结合的阻塞风险规避方法 总被引:3,自引:0,他引:3
提出了一种改进的金融输电权FTR(Financial Transmission Rights)。在此基础上,阐述了基于改进型FTR与基金池相结合的阻塞风险规避方法。给出阻塞风险规避的定量分析。该方法将线路的输电权放在远期市场中和电量一起进行交易。将实际运行中未发生阻塞线路的阻塞交易费全部投入ISO建立的阻塞基金池中。购买了该线路输电权的交易商不被补偿。对购买了实际发生阻塞线路输电权的交易商。将按照一定的原则给予补偿。以实现对阻塞风险的规避。分别对无环流和逆流、有环流、有逆流情况下的阻塞管理进行了仿真。结果说明该方法有效。 相似文献

当电力市场发展到输电系统全面开放以后,输电网问题越来越成为电力市场中保障电力系统安全稳定运行的关键因素。利用金融输电权FTR(Financial Transmission Rights)思想可有效规避输电阻塞给电力市场各发电商带来的风险,但这种交易在线路出现反向潮流时可能会给该线路阻塞费用的承担者尤其是发电商带来一定的利益损失。文中将FTR思想引入到以往远期合约中,提出了一种新型的远期合约形式,并针对如何解决反向潮流存在的问题给出明确方案,这样即可以达到规避现货市场电价风险的目的,又可以实现规避输电阻塞风险。 相似文献

A monthly transmission rights (TR) auction issuing both point-to-point financial transmission rights (FTRs) and flow-gate rights (FGRs) is studied in this paper. Initially, a locational marginal pricing (LMP) based energy market is presented, in which the linear security constrained optimal power flow (SCOPF) problem is solved for each hour of system operation, determining the nodal prices, the transmission link capacity prices and the transmission congestion charges (TCCs) that should be collected by the ISO in case of congestion. A monthly auction is conducted in the TR market issuing FTR obligations, FTR options and FGRs to market players, building a link between all types of transmission rights under the same market structure. Combining the advantages of financial and physical rights, the market efficiency can be enhanced by offering a variety of choices for risk management to market players. The monthly TR auction is tested on several case studies using the IEEE three-area RTS96 and useful conclusions are drawn concerning the utility of the various types of transmission rights as compared to one another, in terms of the reimbursement they provide to their holders. 相似文献

In order to guard forward contracts from the locational marginal price (LMP) volatility, financial transmission rights (FTRs) are issued in the centralized power markets. However, the current FTR system can provide hedge only against the congestion components of LMP differentials. Consequently, the loss components remain unhedged. To bridge the gap, a framework is developed in this paper to implement an FTR system that will provide hedge against the loss prices. The availability of loss-hedging FTRs in addition to the congestion hedging FTRs further reduces the exposure of the forward market participants to the LMP volatility. The loss-hedging framework developed is carefully designed to fit the practical environment. All the primary issues for the implementation of loss-hedging FTRs, such as the revenue adequacy test, auction, and auction revenue rights, are carefully addressed. Revenue adequacy of loss-hedging FTRs can be ensured by means of a test called as the offset capacity test. Some efficient policies are also designed for the successful functioning of loss-hedging FTRs. At the end of the paper, a case study is carried out to assess the effectiveness of the methodology developed. 相似文献

Recent changes in electricity markets have advocated the use of Local Marginal Prices (LMP) for congestion management and pricing. From the perspective of market participants, the LMPs pose a risk since they are not known before a transaction on the grid is made. Financial transmission rights (FTR) are instruments that help market participants hedge this risk and are issuable in two flavors—obligations and options. While pricing obligations are much easier, pricing FTR options pose a significant challenge. In this paper we develop a computational method for pricing FTR options. We also discuss the problem of designing financial instrument sets that assure revenue adequacy for the issuer. We point out the difficulty in assuring revenue adequacy when FTR options are present and propose a scheme for overcoming the difficulty. The proposed pricing method can be used to compute prices of options and obligations in the primary market or as a reliable pricing tool to compute option prices in the secondary market. Finally using a test network we present and discuss numerical results. 相似文献

在电力市场环境中,将阻塞成本的合理分摊与一种新型的金融输电权相结合以进行阻塞管理。在两个电流分解公理的基础上,分三种不同的网络情况阐明了阻塞成本分别在发电侧和用户侧分摊的思想。提出的新型金融输电权,没有容量大小的区别,也没有输电权数量的限制,购买价格完全由交易商自己决定,交易结束后按各交易商当初的输电权购买价格来进行阻塞补偿费用结算。通过建立阻塞基金池,使得规避阻塞风险的金融补偿金有了具体的来源,因此,输电权的具体实施变得真正可行。 相似文献
