摘　　要：近年来,随着清洁能源占比的持续攀升和跨省跨区交易电量规模的日益扩大,我国电力市场建设亟需充分利用输电通道容量以及避免网络阻塞导致交易效率降低的问题。从北欧与美国PJM电力市场的建设经验来看,可用传输容量(available transfer capability,ATC)作为电网跨区功率交换水平的重要量化指标,对于提高输电通道利用效率或降低网络阻塞风险可以起到关键作用。因此,需要紧密结合国外典型电力市场在ATC应用上的相关做法,形成对我国的借鉴与启示,并对ATC如何应用于我国电力市场进行深入研究。首先介绍了ATC的定义及其计算方法。在此基础上,梳理以北欧与美国PJM为代表的典型电力市场中ATC的相关应用情况并进行对比总结。然后,结合我国电网建设和电力市场发展现状,指出目前我国电力市场考虑ATC的必要性,并凝练ATC应用的关键问题。最后,基于国外典型电力市场ATC应用经验和我国实际情况,探讨我国电力市场环境下ATC应用关键问题的解决思路。In recent years, with the continuous increase in the proportion of clean energy and the expanding scale of the trans-regional and trans-provincial electricity transactions, the electricity market in China is in need to make full use of the transmission channels and avoid the network congestion lowering the trading efficiency. Judging from the construction experiences of the typical power markets in Northern Europe and the United States, the available transfer capability(ATC), as an important technical indicator to measure the power exchanges between zones, plays a key role in improving the efficiency of the transmission channel utilization or reducing the risks of network congestion. Therefore, it is necessary to closely integrate the practices of the typical foreign power markets in the application of ATC to form a certain reference and enlightenment for China and conduct the in-depth research on how to effectively apply the ATC in the power market in China. This paper first introduces the definition of the ATC and its calculation methods. On this basis, the application experiences of the ATC in the typical foreign power markets represented by Northern Europe and the United States are compared. Then, from the perspective of China’s power grid construction and power market development status, this paper points out the necessity for the electricity market in China to consider the ATC and the relevant key issues. Finally, the solutions to the key issues of the ATC adapted to the power market environment in China are discussed.
