At present, in the context of accelerating the green and low-carbon transformation of energy and building a new power system, the construction and application of new energy is galloping along the path of high-quality development. The “New Power System Development Blue Book” issued by the National Energy Administration pointed out that the construction of a high proportion of new energy supply and consumption system is the main task of the new power system, and non-fossil energy power generation will gradually transform into the main installation and electricity main body of the new power system.

To increase the proportion of supply and consumption of new energy is by no means a generality. On July 31, the National Energy Administration announced the construction and operation of renewable energy in the first half of 2023 at a press conference. In the first half of this year, 22.99 million kW of wind power was added to the grid.

The average utilization rate of wind power was 96.7%, an increase of 0.9 percentage points year-on-year. In the first half of the year, the country added 78.42 million kilowatts of photovoltaic grid-connected capacity; The utilization rate of photovoltaic power generation is 98.2%, an increase of 0.4 percentage points year-on-year. It is not difficult to see from the above data that China’s new energy not only realizes rapid growth in grid-connected capacity, but also continuously improves the absorption capacity of existing new energy power generation.

In China, since the “14th Five-Year Plan”, the construction of new energy has insisted on both “centralized” and “distributed”, and there are centralized new energy bases built according to the superior resource endowment of each region, and trans-regional clean energy transmission is achieved through a strong power grid with UHV as the core. There are also distributed new energy projects that are spontaneously constructed and self-used in various places, such as distributed photovoltaic projects that effectively utilize rooftop lighting resources of parks, enterprises, and residential buildings in various places through the promotion of user-side new energy construction, etc., to access the power grid in a decentralized manner and with small capacity, and to achieve local consumption through smart microgrids.
