2022-02-25
In order to comprehensively promote the green and low-carbon development of energy, the national development and Reform Commission and the National Energy Administration recently issued the opinions on improving the system, mechanism, policies and measures of green and low-carbon transformation of energy, which aroused great concern of the society. Experts said that there are still some deficiencies in the current energy system, mechanism and policies, such as the infrastructure such as energy transmission does not adapt to the large-scale development of new energy, and the energy market system is not perfect. We should adhere to systematic and overall thinking, and plan the system, mechanism and policy measures of green and low-carbon transformation of energy from the perspective of top-level design. Take new energy as the main body "Clean power sources and electrification of terminal energy consumption are important directions for the structural adjustment of supply side and consumption side. With the increase of the proportion of electricity in the energy consumption system and the large-scale access of new energy power generation projects, it is urgent to build a new power system with new energy as the main body." Yi Yuechun, vice president of hydropower and water resources planning and Design Institute, said. The opinions put forward specific measures from the aspects of power grid construction, key technology improvement and operation system and mechanism. On the one hand, we should evaluate the adaptability of green and low-carbon development of the existing power system, improve the technical level and optimize the system in terms of power grid architecture, power supply structure, source network load storage coordination, digital intelligent operation control, etc. On the other hand, give full play to the role of the power market mechanism, mobilize the system flexibility, coal-fired power units, natural gas peak shaving units, hydropower and other regulatory power sources, as well as the enthusiasm of power demand side loads such as user side energy storage, electric vehicle charging facilities and distributed generation to participate in the regulation of the power system, and through the optimal design of the market mechanism, Fully tap the potential of clean energy consumption in the power system. In June this year, Anhui's first 35 kV "5g + source network load storage" new generation substation demonstration project - Huaibei source network load storage integration demonstration project will be completed and put into operation. It will become an energy hub station integrating various elements of "source, network, load and storage", which will greatly improve the consumption capacity of new energy, cut peak and fill valley, and stabilize the fluctuation of new energy power generation. Wang Kejie, deputy general manager of State Grid Huaibei Power Supply Company, said that after the project is put into operation, the joint role of the source network load storage system will greatly improve the intelligent level of the power grid. At the same time, it is also of milestone significance for serving the development of new energy and helping to achieve the goal of "double carbon". In addition, the Opinions also made systematic deployment in reducing non-technical costs. The relevant person in charge of the National Energy Administration said that the green and low-carbon transformation of energy is essentially the process of production factors flowing from high-carbon fields to low-carbon fields. Strong policy support and guidance are needed to achieve the goal of establishing before breaking and breaking path dependence. The opinions systematically proposes to improve the policies of land, finance, taxation, finance, price and data resources conducive to the green and low-carbon transformation of energy, guide the investment of land, capital, data and other production factors in the field of clean and low-carbon energy, strengthen the coordinated allocation of factors, and accelerate the green and low-carbon transformation of energy. Promote the reform of electricity Marketization The power market-oriented reform empowers the new power system, which is a booster to promote the green and low-carbon development of the power system and realize the flexible, efficient and diversified interaction of the power system. "In view of the problem that the current power grid infrastructure and power system operation mechanism do not adapt to the large-scale development of clean and low-carbon energy, the opinions put forward the solution of power marketization, which will provide institutional mechanism and policy guarantee for the key areas of the construction and operation of new power system, and systematically support the large-scale development of clean and low-carbon energy." Du Zhongming, party secretary and President of the general electric power planning and Design Institute, said. Large power grid is an important platform for China to realize the national optimal allocation of energy resources, which needs to play a further role. The reverse distribution of energy resources and demand in China objectively requires large-scale and long-distance allocation of energy from west to East and from north to south across the country. The opinion proposes to further improve the formation mechanism of inter provincial and inter regional electricity prices and promote the consumption of renewable energy in a wider range. All regions are encouraged to meet the national requirements for renewable energy consumption through cooperation in the proportion of renewable energy or other means. The development experience of the past few years shows that the rapid development of clean and low-carbon energy not only makes outstanding contributions to alleviating the constraints of energy resources and the pressure of ecological environment, but also seriously restricts the healthy and sustainable development of the power industry. The opinions proposes to establish a national unified power market system and speed up the construction of power auxiliary service market. Du Zhongming said that during the "14th five year plan" period, China's new energy will not only further expand the installed capacity, but also put forward higher requirements for the consumption and utilization level of new energy. In order to ensure the high-level consumption and utilization of new energy, it is necessary to form a complete and unified high standard power market system suitable for a high proportion of renewable energy. Innovative rural new energy development and utilization On January 12, the new power system of "common wealth and sharing" digital agricultural park built by State Grid Jiaxing Power Supply Company was put into commercial operation in Zhejiang Pinghu Agricultural Economic Development Zone (Guangchen town). "This mode enables the agricultural park to share the electricity generated by clean energy and enjoy the dividends of hydrogen energy, photovoltaic, energy storage and charging pile construction, which not only meets the energy demand of enterprises, but also reduces the investment cost of electricity, providing a strong driving force for accelerating the upgrading of traditional agriculture." Xu Jianjun, deputy secretary of the Party Working Committee of Pinghu Agricultural Development Zone (Guangchen town), said, "the project is expected to realize an annual income of 1.46 million yuan. The problem of energy consumption has been solved, and more and more enterprises have come. Now we all call it 'agricultural Silicon Valley'." The green transformation and development of energy in rural areas is an important part of building a modern energy system. It is of great significance to consolidate and expand the achievements of poverty alleviation, promote rural revitalization, achieve the "double carbon" goal and agricultural and rural modernization. Rural energy consumption mainly includes domestic energy consumption such as cooking, heating and lighting, as well as production energy consumption such as agriculture, forestry, animal husbandry and fishery. Since 1979, the carbon emission of energy consumption in agriculture has been on the rise. The carbon emission of energy consumption has continued to rise from 30.02 million tons in 1979 to 237 million tons in 2018, an increase of nearly seven times. Under the dual historical responsibility of "double carbon" goal and Rural Revitalization Strategy, rural energy transformation is imminent. The opinions made it clear to innovate the development and utilization mechanism of rural renewable energy. Encourage the use of land suitable for decentralized development of wind power and photovoltaic power generation in rural areas, and explore the investment and operation mode of renewable energy projects with unified planning, decentralized layout, agricultural enterprise cooperation and benefit sharing. Rural collective economic organizations are encouraged to invest in renewable energy power generation projects with specialized enterprises by means of land use rights, joint ventures and so on. Experts said that the transformation of rural energy is a complex subject, and it is necessary to prevent mass action and repeated construction. Before large-scale promotion, priority can be given to promoting the green and low-carbon pilot of rural energy in the key assistance counties for rural revitalization, making full use of local resource endowments, selecting appropriate new energy varieties and development models, giving priority to local and nearby consumption, reducing energy transmission distance and transformation links, and improving the comprehensive utilization efficiency of rural energy resources.
