REX521GHHGSH07G The “Three North” region is the most abundant area of wind energy and solar energy resources in China, while the load center of our country is concentrated in the central and eastern regions, the geographical characteristics of the reverse distribution of load center and resource center is the main contradiction restricting the development of new energy in our country. In order to solve this contradiction, we need to start from many aspects:
A large base with multiple complementary capabilities. Due to the obvious volatility and intermittency of new energy power generation, it is difficult to realize the full transmission of new energy power by UHV lines. China’s “14th Five-Year Plan” pointed out that “to build a number of multi-energy complementary clean energy base”, by matching a certain proportion of adjustable power sources, such as thermal power, hydropower, etc., to achieve multi-energy complementary, to promote new energy consumption.
Uhv transmission. In 2020, 22 UHV lines will deliver 531.8 billion kWh of electriciREX521GHHGSH07G ty annually, of which 244.1 billion kWh is renewable energy, an increase of 3.8%, and renewable energy accounts for 45.9% of the total electricity. It opens up the conversion channel of resource advantage and economic advantage, and eases the imbalance of load center and resource center in our country to a certain extent.
Distributed new energy. Distributed energy has the advantages of flexible layout and high energy utilization efficiency. In theory, the development of distributed new energy economy close to the load center is another important method to effectively solve the contradiction of reverse distribution in addition to UHV engineering and multi-energy complementary large-base method.
“China’s eastern cities should give priority to the development and use of ‘around’ energy, coupled with the” distant “energy sent from the west to the east, eastern energy self-sufficiency and west-east power transmission combination, should not wait for the west to supply the east, but should change the way of thinking, self-proREX521GHHGSH07G duction and self-marketing of energy, continue to increase the proportion of energy self-sufficiency.”
In the future, China will build a centralized and distributed renewable energy development pattern through the construction of multi-energy complementary large bases, trans-regional UHV transmission and distributed new energy construction, and promote the development of new energy.
