The ecology of the power industry is accelerating and reshaping

“My countryClean energyIt provides strong support for the green and low-carbon transformation of energy." "my country's clean energy development and utilization scale is firmly ranked first in the world", "my country has formed a relatively complete clean energy technology industry system", "The ecology of the entire energy and power industry is being reshaped"... This is the voice reporter heard at the "2023 China International Clean Energy Expo Opening Ceremony and China Clean Power Summit" recently held.

The experts at the meeting unanimously agreed that my country's non-fossil energy is expected to achieve leapfrog development again this year. In the process of the integration of new energy and traditional energy, it is necessary to focus on how to ensure the safety of energy supply and security, andNew power systemAccelerate the coordination and promotion of all aspects during the construction process.

■■Non-fossil energy by the end of the year

Installation ratio is expected to exceed 50%

my country's clean energy development and utilization scale ranks first in the world, providing strong support for the green and low-carbon transformation of energy. Data from the National Energy Administration shows that as of the end of 2022, the installed capacity of renewable energy power generation and nuclear power reached 1.27 billion kilowatts, accounting for 49.5% of the total installed capacity of national power generation. In 2022, the national renewable energy power generation reached 2.7 trillion kilowatt-hours, accounting for 31.3% of the national power generation, and 80.6% of the national new power generation has been built, which has become the main body of my country's new power generation. In particular, the installed capacity of wind power photovoltaics has exceeded 700 million kilowatts, equivalent to more than 30 Three Gorges Power Stations. "my country has formed a relatively complete clean energy technology industry system, such as million kilowatt-hour technology, low-wind-speed wind power technology, and photovoltaic battery high-speed conversion technology, all of which are leading the world, injecting strong impetus into the vigorous development of new clean energy models and new business formats." Huang Xuenong, regulatory director of the National Energy Administration, said.

An Hongguang, full-time vice chairman of the China Electric Power Enterprise Federation, said that according to statistics from the China Electric Power Enterprise Federation, my country added 200 million kilowatts of new power generation capacity in 2022, and the newly added non-fossil energy power generation capacity reached 160 million kilowatts, continuing the overall trend of China's green power transformation in recent years. It is estimated that by the end of 2023, the national installed capacity will reach about 2.81 billion kilowatts, and the installed capacity of non-fossil energy power generation will reach 1.48 billion kilowatts, accounting for 52.5% of the total installed capacity. Under the background of the "dual carbon" goal, my country's energy structure will continue to be adjusted and optimized, and the clean energy industry will have broad future prospects, and it is expected to usher in new development opportunities again and achieve another leapfrog development.

■■ Collaborative innovation is the key

The huge amount of clean renewable energy is connected to the grid, which will cause major adjustments to the functional positioning and characteristics of each link of the power system transmission, transmission and distribution. Clean energy generation such as wind and light will gradually change from providing electricity supplement to providing electricity support. In the view of industry experts, the above-mentioned transformation has accelerated the transformation of "source and load movement" to "source and load interaction". The key to the construction of a new power system is how to coordinate and promote it in all aspects.

Wang Zhixuan, deputy director of the China Electric Power United expert committee and director of the Institute of New Energy Systems and Carbon Neutrality of North China Electric Power University, said: "The new power system does not solve the problem of new energy consumption, and does not solve only one link. Instead, it must be systematically considered from multiple aspects such as technology, policies and markets. For example, there are currently more than 3,600 standard operating standards for power system, which require overall coordination and promotion."

Ma Li, deputy chief engineer of the State Grid Energy Research Institute and director of the Institute of Corporate Strategy, also believes that the key to solving the power supply of high proportion of renewable clean energy to ensure safety and promote wind power photovoltaics to reduce costs and improve efficiency is collaborative innovation. The first collaboration is the collaboration between the scale and development space of new energy and traditional energy. The functional positioning of each power supply plays a different role in different stages, provinces, and energy sources. The scale of each power supply needs to be determined in accordance with the situation of each province. The second collaboration is the coordination of the mechanism between new energy and traditional energy participating in the market. In the process of the integration and development of new energy and traditional energy, more new entities such as coal-fired power, wind power, photovoltaics, energy storage, electric vehicles, etc. have entered the market to participate in transactions. At present, the mechanism between new energy and traditional energy participating in the market has not yet played a synergistic function.

■■Construction of new power system

Need to top-level planning and design

So, how to solve the problem of coordinated development in the current construction of new power systems? Industry experts unanimously stated that the construction of new power systems requires top-down planning and top-level design, as well as a combination of bottom-up technology and industrial innovation.

Wang Zhixuan believes that the "new" of the new power system is not only a new form, but also a series of innovative "new" of the power system, including innovations in traditional power supply, power grid, electricity consumption, energy storage and other technologies and management. The construction of a new power system is quite complex, involving various aspects such as regulations, policies, systems, technologies and framework construction, and top-level design is needed.

Liu Yiyang, deputy secretary-general and spokesperson of the China Photovoltaic Industry Association, told reporters that under the background of "dual carbon", a new power system with new energy as the main body is being accelerated and needs to be coordinated and planned and scientifically deployed. On the one hand, we must enhance the hematopoietic function of new energy itself. While continuing to increase the construction of wind power photovoltaic projects and ensuring the steady increase in the proportion of new energy, we must strengthen technological breakthroughs, actively optimize the grid connection characteristics of new energy, and enhance the support and regulation capabilities of new energy on the power grid system. At the same time, improve the consumption capacity of new energy power grids, build a highly flexible, flexible and intelligent power system as soon as possible, and formulate corresponding incentive mechanisms in terms of system and mechanism.

"The goal of building a new power system is to promote the evolution of the power system toward large-scale and high-proportion new energy development. The key points of building a new power system are to build a suitable source grid and load storage link, as well as market system and mechanism." Lin Wuxing, deputy general manager of the Power Market Service Department of State Grid Digital Technology Holdings Co., Ltd., believes that "the entire power market operation needs policy or mechanism guarantees, such as market improvement and price improvement. We hope that the government and various market entities will make further efforts to promote the improvement of the power market mechanism."
