Help the high-quality development of new energy sources
Energy security and safety are related to the national economy and people’s livelihood, and they are the "big country" that cannot be ignored for a moment. Since the 18th National Congress of the Communist Party of China, the construction of China’s new energy system has been accelerated, and the foundation of energy security has been continuously consolidated, which has provided strong support for economic and social development. At the same time, we should also see that China’s energy development still faces a series of challenges, such as huge demand pressure, more supply constraints, and arduous tasks of green and low-carbon transformation. When presiding over the 12th collective study of the 20th the Political Bureau of the Communist Party of China (CPC) Central Committee, General Secretary of the Supreme Leader pointed out: "The way out to meet these challenges is to vigorously develop new energy sources." This has pointed out the direction for us to promote the high-quality development of new energy and provide safe and reliable energy guarantee for Chinese modernization.
China is rich in wind power, photovoltaic and other resources, and has great potential for developing new energy. In recent years, China’s new energy development has achieved remarkable results, the installed capacity ranks first in the world, the proportion of power generation has steadily increased, and the cost has dropped rapidly. Among them, the integration of river basin water and scenery is becoming a new development direction. The integration of river basin water and scenery refers to the complementary development of hydropower, wind power and photovoltaic power generation by fully tapping the hydropower regulation capacity, relying on the cascade hydropower, hydropower expansion and pumped storage development in the river basin. It is of great significance to speed up the integrated development of river basin water and scenery.
It is conducive to ensuring national energy security. General Secretary of the Supreme Leader pointed out: "The rice bowl of energy must be in your own hands." Energy is the blood of modern society. Since the founding of New China, especially since the reform and opening up, we have been able to create two miracles of rapid economic development and long-term social stability, which cannot be separated from the important support provided by the energy industry. On the new journey, sufficient and stable energy supply with affordable price is the inherent requirement of promoting Chinese modernization. At present, China has basically formed an energy production system driven by coal, oil, gas, electricity, nuclear, new energy and renewable energy, and its energy supply guarantee capacity has been continuously enhanced. To build a strong energy country and ensure energy security on the new journey, we must base ourselves on domestic diversified supply to ensure safety, persist in promoting the adjustment of energy structure and industrial structure, and firmly hold the energy rice bowl in our own hands. Rich in coal but poor in oil and poor in gas is China’s national condition, and the development of new energy plays a very important role in ensuring national energy security. Implementing the integrated development of water, scenery and scenery in the basin can maximize the utilization efficiency of water and scenery resources in the basin, at the same time, take into account the requirements of environmental protection, safety and cost, enhance the capacity of new energy supply, and grasp the strategic bottom line of self-sufficiency in domestic production of important energy.
And is beneficial to realize that carbon neutrality goal of peak carbon dioxide emissions. General Secretary of the Supreme Leader pointed out: "Promoting carbon neutrality in peak carbon dioxide emissions is a major strategic decision made by the CPC Central Committee after careful consideration, a solemn commitment to the international community and an inherent requirement for promoting high-quality development." Achieving carbon neutrality in peak carbon dioxide emissions is a wide-ranging and profound economic and social change, which can never be achieved easily. Activities related to energy production and consumption are the main sources of carbon dioxide emissions. Promoting the green and low-carbon transformation of energy is an important measure to do a good job in carbon neutrality in peak carbon dioxide emissions. Wind power, photovoltaic power generation, hydropower and so on do not emit pollutants and greenhouse gases, and are natural green energy sources. Wind power and photovoltaic power generation have the characteristics of randomness and fluctuation. Through optimal dispatching and rapid and flexible adjustment of hydropower units, wind power and photovoltaic power generation with random fluctuation can be adjusted into smooth and stable high-quality power supply. Accelerating the integrated development of river basin water, scenery and scenery is conducive to further enhancing the transformation power of green and low-carbon energy development, promoting the development of China’s energy and power system in a clean, low-carbon, safe and efficient direction, and helping peak carbon dioxide emissions achieve the goal of carbon neutrality.
It is conducive to promoting the high-quality development of new energy. The General Secretary of the Supreme Leader pointed out: "We should follow the trend and take advantage of the situation to promote the high-quality development of new energy in China with greater efforts." At present, there are still some restrictive factors in the development and utilization of new energy in China, such as insufficient adaptability of power system to large-scale and high-proportion new energy connection and consumption, and obvious constraints on land resources. The integrated development of river basin water, scenery and pumped storage organically integrates the characteristics of rapid response and large-scale energy storage of conventional hydropower and pumped storage with the cost advantage of large-scale development of new energy, which has the technical and economic feasibility of large-scale development in a short period of time. First, the new energy resources around China’s large-scale hydropower bases are in good condition, and the development of river basin water, scenery and integrated bases has natural conditions. Second, it can effectively improve the grid-connected pressure of new energy, greatly alleviate the impact of new energy generation on grid frequency and reactive voltage, and effectively support the dynamic balance of power system. Third, it can effectively play the seasonal compensation role of wind power and photovoltaic power generation, significantly increase the external power transmission during the dry season of hydropower, improve the power supply capacity, and effectively improve the utilization rate of transmission channels.
As an important promoter of the integrated development of river basin water and scenery, China Electric Power Construction Group Co., Ltd. thoroughly studied and implemented the Supreme Leader’s New Era Socialism with Chinese characteristics Thought, gave full play to the advantages of the integration of "planning, design, investment, construction and operation" in the whole industrial chain, scientifically planned and built a new energy system, and actively implemented the integrated development of river basin water and scenery. First, the investigation of water and scenery resources and the study of hydropower expansion potential in major river basins have been basically completed, and the project library of water and scenery integration construction in major river basins has been established, which has accumulated basic data resources for the implementation of water and scenery integration development and construction in river basins. Second, consider the development and construction cycle of various power sources, mainly adjust the construction progress of power sources and delivery channels, the economic and social development needs of the receiving market and the development needs of the power market, coordinate the project construction with rural revitalization and infrastructure construction, reasonably draw up the power development timing and promotion measures of the base, and create an integrated development system with unified planning, organic integration, efficient development and scientific management. Thirdly, a series of basic technology research and industrial chain construction work were organized around key topics such as planning and design, construction, dispatching and operation, equipment manufacturing, electricity price mechanism, digital management, and a number of original technologies with independent intellectual property rights were formed. The fourth is to promote the construction of a global renewable energy database and planning platform, which has been applied by dozens of countries in Southeast Asia, Central Asia, Africa, South America and other regions. Facing the future, we should conscientiously implement the spirit of the important speech of the Supreme Leader General Secretary and the decision-making arrangements of the CPC Central Committee.Actively contribute to the high-quality development of new energy in China.
