In recent years, with the continuous increase in the promulgation of distributed energy policies, the continuous recognition of the importance of distributed energy, and the continuous launch of new distributed energy projects and energy companies into the market, China’s distributed energy has developed rapidly.
On January 1, 2006, the “Renewable Energy Law of the People’s Republic of China” came into effect. In September 2007, the National Development and Reform Commission formulated a renewable energy development strategy and made a long-term plan for distributed power generation, especially distributed power generation based on renewable energy. In 2012, the National Energy Technology “Twelfth Five-Year Plan” issued by the National Energy Administration listed distributed energy technology as one of the four key areas of technology. It has identified major energy application technologies and engineering demonstration projects including large-scale wind power generation technology, high-efficiency large-scale solar power generation technology, large-scale multi-energy complementary power generation technology, and high-efficiency utilization technology of biomass energy.
In 2013, the “Interim Measures for the Management of Distributed Power Generation” promulgated by the National Development and Reform Commission made a clear definition of distributed power generation. In the same year, the State Grid Corporation of China also issued the “Opinions on Doing a Good Job in Grid-connected Distributed Power Supply Services”, which set standards for the allowed grid-connected distributed energy, and promised to provide many conveniences for distributed energy projects to connect to the grid. .
Since then, the State Grid Corporation of China has issued a number of specifications, such as “Typical Design of Distributed Power Supply Access System”, “Distributed Power Supply Dispatch Operation Management Specification” and “Technical Specifications for Relay Protection and Safety Automatic Devices of Distribution Network Accessed to Distributed Power Supply” and other service specifications. Many supporting measures in various regions and cities, such as electricity price subsidy programs, have also been promulgated and implemented accordingly. In 2015, various good news such as the new power reform policy and the proposal of the energy Internet were successively promulgated, and distributed power generation ushered in an important moment of rapid development. The new power reform clearly proposed the development of distributed energy, and pointed out that the fair access to the power grid should be opened, and a new mechanism for the development of distributed power should be established.
At the same time, the new power reform policy also pointed out that users or microgrid systems that use distributed power sources are allowed to participate in power transactions. This measure will greatly enhance the enthusiasm of ordinary users to participate in distributed power generation projects and contribute to the development of distributed energy. The issuance of these policies and regulations has broken through the many difficulties faced in the actual operation of distributed power sources, and has truly realized the legalization and orderliness of distributed power sources, which is of pioneering significance for the promotion of distributed power generation. After the policy was liberalized, many individual and corporate self-generation users across the country submitted applications and successfully connected to the grid, which became an important turning point in the development of distributed power generation. The Ministry of Science and Technology of the People’s Republic of China has also given great support to the related basic research and demonstration projects of distributed power generation technology through the 973 Program and the 863 Program. All these have cleared the obstacles for the development of distributed power generation, and it is expected that distributed power generation will quickly enter the mature stage. According to statistics, in 2015, China’s renewable energy consumption increased by 20%, of which solar energy increased by 69.7%, wind energy increased by 15.8%, and natural gas increased by 4.7%. It is planned that by 2020, the total installed capacity of distributed energy power generation will reach 130 million kW.
