March 8, 2017, the National Energy Bureau Consolidated Division issued a "circular on the launching of a distributed generation market-oriented transaction pilot (draft)" (hereinafter referred to as "Draft for soliciting opinions"), in the pilot area, the construction of PV power plants, wind power, and the scale of the construction and regional total construction, according to the amount of market-oriented transactions, can be established, and the construction scale of individual projects is not more than 210 million. The pilot region predicted the scale of construction by 2020 when submitting the pilot programme, and the annual scale of construction could be presented in phases in implementation. In the pilot, such as to ensure that the distribution of the grid in the vicinity of the distributed generation projects can be all transactions, but also open the pilot region of the total construction scale. In the draft for comments, it is clear that the NDRC, the National Energy Bureau will approve the first pilot programme and complete the pilot scheme in advance, and may be separately approved before 31 May 2017. Electric power experts have said the future grid is distributed in the form of self-control, local power grids reduce the disturbance to large grids. Therefore, the maximization of local equilibrium in micro-grid is the inevitable trend in the future evolution of power grids. In the future, distributed photovoltaic as an important part of the future distributed intelligent micro-network, the demand will increase dramatically in the process of gradual maturation of power trading market and intelligent micro-grid technology.
