Under the reform of power market, as an efficient functional system of energy comprehensive utilization, distributed energy has gained more and more attention. After more than 20 years of development, distributed energy has achieved phased results, and its combination with large power grid is considered to be one of the main directions of future power market development, and its future development can be expected.
The development of distributed energy in China has experienced three stages, namely, the primary stage, the substantive implementation stage and the transition stage. Although the overall development is relatively slow, there is still considerable progress. Next, after participating in the power market competition, it will further play the role of distributed energy, including improving energy utilization, reducing environmental pollution, and improving the security of power supply system.
