Actively promoting the construction of green electricity market is an effective way to promote the green and low-carbon transformation of energy consumption and realize the goal of carbon emission peak and carbon neutrality. China has already started the construction of green electricity market, which is currently in the period of rapid development. There is an urgent need to study the related key issues to provide the support for the construction of green electricity market. This paper analyzes the connotation of green power and green electricity market, and studies the practice of green electricity market in foreign countries from the aspects of policy design, operation mechanism, application scenarios, and support technology with the United States and Europe as typical cases, and puts forward relevant inspiration. On this basis, combined with the progress of green electricity market construction in China, this paper discusses the key issues of green electricity market construction in China under the goals of carbon emission peak and carbon neutrality, and puts forward the key mechanism design and technical difficulties that need to be solved in the green electricity market construction of China from four aspects of top-level design, key mechanisms, connecting mechanisms, and support technologies.
