In November 2017

China issued Notice on the Pilot Market-based Trading of Distributed Generation(hereinafter referred to as ‘Notice')

which opened the curtain of market-based distributed generation trading. Considering distributed generation trading is still in the pilot stage in China

some problems such as the trading mode and trading mechanism need further exploration. Firstly

the basic concepts and characteristics of distributed generation trading are expounded

and three main foreign distributed generation trading mechanisms and their application and development status are summarized. This paper makes a comparative analysis of the pilot trading model given by the Notice

and then focuses on the analysis of three representative peer-to-peer(P2P)energy trading platforms located in the United Kingdom

Germany and the United States. Finally

the future development of distributed generation trading in China is discussed

hoping to provide some reference for the development of China's power trading.
