适应中国电力市场改革现状的输电权分配机制

针对现货市场改革后不同发电主体之间利益分配变化较大的问题，提出了一种实用的市场过渡方案。首先，介绍中国中长期交易市场和现货市场的基本情况，分析现货市场运行后可能存在的问题；然后，从福利分配和产权公平的角度，提出通过分配金融输电权（financial transmission right，FTR）解决现有问题的市场改革过渡方案。该方案考虑现货市场改革前后输电权的所有关系，根据输电权的基本理论，将部分输电权分配给发电企业的输电权机制。通过IEEE 14节点算例对该方法有效性的验证表明，该种机制可以在不影响市场效率的情况下缩小现货市场后不同发电企业之间的利益变化，有利于市场的平稳过渡。

Financial Transmission Right Mechanism and Its Application in China Electricity Market

The electricity spot market reform in China has led to a significant change in revenues for different power generation entities. Aiming at this problem, this paper proposes a practical market transition scheme. Firstly, the paper introduces the basic situation of long-term electricity transaction market and spot market in China, and analyzes the possible problems after the operation of spot market. And then, from the perspective of equity property rights and welfare distribution, a transition scheme for electricity market reform is proposed to solve the existing problems through allocating financial transmission rights (FTRs). In the proposed scheme, based on the FTRs before and after spot market reform, a new FTR mechanism is proposed according to the basic theory of FTR, which is to allocate a part of FTRs to the power generation enterprises. A case study of an IEEE-14 bus system was carried out to verify the effectiveness of the proposed scheme, which shows that the proposed mechanism can reduce the revenue changes between different power generation enterprises without affecting the market efficiency, and is conducive to the smooth transition of the electricity market.
