The construction of microgrids will force electricity reform to promote the development of the new energy industry

Recently, the National Energy Administration issued the Guiding Opinions on Promoting the Construction of New Energy Microgrid Demonstration Projects (hereinafter referred to as the Opinions).

The "Opinions" proposed that the construction of new energy microgrid demonstration projects will be promoted, and all provinces (autonomous regions and municipalities) need to report new energy microgrid demonstration projects
.

It is reported that microgrids are in their infancy internationally, and China's current power system is still not fully adapted to the innovative needs
of microgrid development.
The next step is to further open the market through power reform and encourage more enterprises to participate in the construction of
microgrids.
According to the Opinions, the new energy microgrid is based on the construction of local distribution network, wind, solar, natural gas and other distributed energy resources multi-energy complementarity, with a high proportion of new energy power access, can achieve a basic balance between local energy production and energy load through energy storage and optimal configuration, and can flexibly interact with the public power grid and operate relatively independently as needed
.

Compared with the traditional power grid, the microgrid does not support centralized large-scale thermal power and hydropower, and its power supply is decentralized, mainly distributed energy such as wind power, photovoltaic, biomass energy, etc.
, the load is also dispersed, and the electricity is mainly
consumed locally.
Due to the instability of clean and renewable energy, whether it is a networked microgrid or an independent microgrid, it is necessary to abide by the principle of "multi-energy complementarity and self-containment", combine various types of distributed energy resources, power storage heat storage (cold) and high-efficiency energy use technologies, and form an efficient integrated distributed energy system based on renewable energy through smart grid and integrated energy management system
.

Microgrid is not a new thing in China, during the "Twelfth Five-Year Plan" period, the government plans to build 30 microgrid projects, which are currently mainly used to solve the problem
of electricity consumption in remote areas and islands.
In the future microgrid, all enterprises and households can participate in clean energy production through distributed energy resources, and can build clean power generation
on home roofs, office roofs, factory roofs, around homes, etc.
Microgrid actually treats mini-grids and distributed energy resources as a whole and achieves effective interaction
with users.
The "Opinions" also clearly stated that the microgrid will establish a two-way interactive relationship with the public power grid and flexibly participate in electricity market transactions
.

At present, the key to the construction of microgrids is economic issues, and microgrids need to be supported by powerful power sources, which will inevitably lead to increased
costs.
Due to the high cost of microgrid construction and the subsidies for new energy microgrid projects in Europe and the United States, the industry had expected that the Energy Bureau would introduce relevant subsidy measures
.
However, to the slight disappointment of the industry, this opinion did not mention the subsidy policy, but only said that "the new energy microgrid is economically reasonable with certain policy support"
.
Some insiders analyzed that although the "Opinions" did not mention subsidies, it was still a normative benefit for the industry, which could promote the absorption of new energy, force electricity reform, and promote the development of
the new energy industry as a whole.
