Most of the microgrids are distributed in cities, with these mainly grid-connected microgrids helping to solve the problems of high electricity prices and the need for meeting business-specific electricity demand for commercial

Policies and ethics China Southern Power Grid Co., Ltd. (hereinafter referred to as CSG) was established in 2002. CSG invests, constructs, and operates power networks in Guangdong, Guangxi, Yunnan, Guizhou, and Hainan provinces and regions.
Decarbonization of the Southern Power Grid in China is feasible by 2060 but requires converting a large cropland area to support solar and wind energy; expansion of hydropower will impact the transboundary rivers according to a power system optimization model set up for 2020–2060.
In 2004, China began to carry out research on the concept of microgrids as proposed by the United States. This research has been based on the connection of distributed generation to large electrical grids via AC (alternating current) microgrids and the impacts of microgrids on large grids.
It is predicted that by 2020 China’s distributed energy microgrid technology will reach the international advanced level. As domestic and foreign supply and demand conditions are difficult to balance in the short term, the microgrid industry has a strong market demand.
With the continuous deepening of research, experience has been accumulated in China in the planning and design, operation control and energy management of AC microgrids. In more recent years, Chinese scholars began to simulate DC (direct current) microgrids.
It is estimated that China will build about 50 distributed energy microgrid demonstration projects by 2025, forming a distributed microgrid technology system, market system and management system.
