    摘要:

    随着可再生能源发电技术的成熟及安装运行成本的不断降低,分布式发电得到了快速的发展,并由此产生了大量的电力产消者。然而分布式发电由于容量小、波动性大、分布零散等特点,并不适合参与现行的电力市场。针对此问题,文中结合国外电力零售市场研究和中国分布式电力交易的实际情况提出了一种配电网层面下的分散式电力市场模式,并分别从市场定义、参与主体、交易方式、时间尺度、出清方式等方面进行了分散式电力市场的框架设计。然后,针对分散式电力市场交易平台难以建立的问题,研究了将区块链技术应用于分散式电力市场构建的可行性及交易实现流程。最后,分别从政策法规和市场建设要点2个方面分析了构建分散式电力市场需要注意的问题。

    Abstract:

    With the maturity of renewable energy generation technology and the reduction of installation and operation costs, the distributed generation have been rapidly developed, and a large number of electricity prosumers have been generated. However, due to the characteristics of small capacity, high volatility and scattered distribution, the distributed generation is not suitable for participating in the existing electricity market. Combined with the research of foreign electricity retail market and the current distributed generation trading situation in China, this paper proposes a decentralized electricity market (DEM) mode at the level of distribution network. The framework design of DEM is carried out from the aspects of market definition, participants, trading methods, time scale and clearing methods. Aiming at the problem that the DEM trading platform is difficult to establish, this paper studies the feasibility and transaction realization process of blockchain technology applied in DEM. Finally, from the perspectives of policies, regulations and key points of market construction, the issues to be paid attention to in the construction of DEM are analyzed.
