In recent years, the global energy consumption structure has accelerated to a clean and low-carbon development, and China has vigorously promoted the development and utilization of renewable energy in order to achieve the goal of carbon peaking and carbon neutrality. The rapid development of distributed photovoltaic power generation has effectively increased the proportion of clean energy and played an important role in realizing the national low-carbon strategy. Three kinds of operation modes of distributed photovoltaic in China are analyzed and summarized, and the economic benefits of different operation modes of distributed photovoltaic projects are quantitatively analyzed with practical cases. The research results can provide reference for the selection of operation modes of distributed photovoltaic projects.
