Microgrid construction and then get good policy support. July 24, the national development and reform commission, the national energy bureau jointly issued “promote grid-connected microgrid construction trial approach” (hereinafter referred to as “trial approach”), to encourage governments around the development of microgrids to give supporting policies to support the gradual establishment of centralized and distributed synergistic energy production and consumption system. In order to improve the construction efficiency, the “Trial Measures” specifically proposed to encourage local microgrid project construction and operation through the PPP model. In the industry's view, the current pressure on China's power grid has increased, microgrid is conducive to enhancing the efficient application of distributed power supply, to achieve a reliable supply of multi-line energy.

The so-called microgrid is a small power generation and distribution system that is different from the main power grid. The Trial Measures make it clear that the microgrid power source consists of distributed power sources, electricity loads, etc., and can adapt to the rapid development of new energy, distributed power sources and electric vehicles, etc., to meet the diversified access and personalized needs. Some experts further introduced that the internal power of microgrid comes from distributed energy sources such as natural gas, photovoltaic and wind power. In the northwest and other places with sufficient wind and light resources to build large-scale wind farms, photovoltaic power stations, users in the access to small wind turbines, photovoltaic and other power equipment, it will enable the power to be consumed in the vicinity of the elimination of losses in the transmission of the grid, and improve the efficiency of energy use.

Some analysis pointed out that with the power supply peaks and valleys of the difference is getting bigger and bigger, China's power grid pressure is increasing day by day, and new energy power plants on the use of solar power, further exacerbating the supply and demand peaks and valleys of the difference, at this stage, the solution is to develop and improve the grass-roots power grids, that is, micro-energy networks or micro-grids, through the combination of consumption and production, to solve the problem of mutual conversion of electricity and other energy, but also solves the problem of new energy outlets.

This “Trial Measures” points out that the microgrid power supply should be based on local renewable energy generation, or power generation type targeting the comprehensive utilization of energy such as natural gas multi-supply, and encouraging the use of fuel cells and other new clean technologies. Among them, the installed capacity of renewable energy accounted for more than 50%, or the comprehensive energy utilization efficiency of natural gas multi-connected supply system is more than 70%. While the microgrid source - network - load integrated operation has a unified operating body, the “Trial Measures” encourages local governments and social capital cooperation (PPP), franchising and other ways to carry out the construction and operation of microgrid projects. In addition, grid enterprises can also participate in the new construction and renovation (expansion) microgrid, investment and operation of independent accounting, shall not be included in the permitted cost.

“In the process of microgrid construction, the assembly of inductors, distributed energy, energy storage equipment requires a lot of money, if you can attract private capital through the PPP model to enter, will effectively improve the construction efficiency,” Han Xiaoping, chief information officer of the China Energy Network, told the Beijing Business News reporter, China's existing microgrid project basically completed the functional complementarity But in the demand side interaction is slightly lacking, “one of the core characteristics of the microgrid is to realize the power near the consumption, but according to China's current power transmission and distribution model, all the power needs to be distributed through the grid company unified distribution to the user's hands, which pushes up the price of electricity, but also reduces the efficiency of electricity, is the urgent need to reform the link.”

National Energy Board of New and Renewable Energy New Energy Division Director Kong Tao pointed out that the future microgrid work in the planning of a higher degree of difficulty is to explore the microgrid trading model, that is, combined with the requirements of the power system, to explore the distributed new energy microgrids, microgrids into an independent power sales rights of the market, can be given to all the users of the microgrid within the electricity supply to the new energy microgrids as a carrier for the independent power sales main body. Carry out PV direct supply or interact with nearby new energy projects.
