China's new generation power system construction policy recommendations

the current large-scale access to electricity of wind power, photovoltaic power generation and other renewable energy sources with significant volatility and intermittency has brought challenges to the safe and stable operation of the power system. In the short term, the most feasible way to solve the problem of renewable energy and consumption is to carry out flexible transformation of thermal power units, reduce the minimum output of coal-fired power units, especially thermal power units, and promote thermal power units to participate in deep peak shaving. However, in the long run, on the basis of technological development and innovation, promoting the transformation and upgrading of power system and building a new generation of power system is the fundamental way to adapt to the high proportion of renewable energy access and promote energy transformation

connotation and overall goal of the new generation power system

under the new situation of large-scale development and utilization of clean energy on the supply side and deep substitution of fossil energy on the consumption side, China's power system will change to a sustainable comprehensive energy power development mode - the new generation power system, which has a high proportion of renewable energy access, the combination of centralized and distributed power, the coordinated development of backbone power and local power, and micro power

the essential goal of the construction of the new generation power system is clean, low-carbon, safe and efficient. Guided by increasing the proportion of renewable energy, strengthening the energy allocation and transmission capacity, and optimizing the energy utilization mode, it has formed a wide range of interconnection, intelligent interaction, flexibility, safety and controllability through the integration of advanced technologies such as advanced power transmission and distribution, large-scale energy storage, new energy friendly combination, source load storage interaction, intelligent control and so on The new power system with open and shared features helps China achieve its energy transformation goal

in combination with the specific requirements of the energy production and consumption revolution strategy (2016-2030) for China's future total energy consumption and energy structure, taking 2025 and 2035 as the two main level years, the overall goal of the new generation power system construction can be quantified as: by 2025, non fossil energy will account for more than 18% of the primary energy consumption and non fossil energy power generation will account for more than 42%, The proportion of electric energy in the final energy consumption shall strive to reach 25%; By 2035, the proportion of non fossil energy in primary energy consumption will exceed 27%, the proportion of non fossil energy power generation will exceed 55%, and the proportion of electric energy in terminal energy consumption will strive to reach 30%

constraints on the construction of the new generation power system

a good policy environment is an important foundation for the orderly development of the new generation power system. At present, China has established the basic strategic planning for the development of the power system under the background of the energy revolution, but there are still many institutional and institutional factors that can not meet the development of the new generation power system, such as insufficient overall planning, imperfect market mechanism, energy storage price system has not been established Unclear supporting policies for key technology industries, etc. Based on the development needs of the new generation power system, this paper will deeply analyze the system and mechanism factors restricting the construction of the new generation power system in the existing policy environment from the aspects of strategic planning, economic policy, fiscal policy, investment and financing policy, regulatory mechanism, etc

strategic planning level

at the planning level, China's energy system is currently divided into coal, oil, natural gas and electric power subsystems according to energy types. The planning of various subsystems is relatively independent, and there is no overall planning mechanism, so it is difficult to achieve the integration, complementarity and cascade utilization of different energy supply systems. In addition, the internal source, load and storage planning of the power system is also based on decentralized planning. The uncoordinated development between various power sources, electricity and load demand has become a key factor restricting the consumption of renewable energy in China

at the management level, the planning, construction, investment and operation of energy subsystems such as coal, oil, natural gas and electric power belong to different competent departments. There are management barriers between various types of energy, and it is difficult to coordinate the management policies issued by various competent departments. At the same time, there are also problems of multiple management and policy contradictions within the power system

at the level of standard system, there is a lack of a new generation of power system specification and standardization system. The construction of the new generation of power system involves multiple fields of source, load and storage, and covers multiple industries such as information, technology and equipment. Without a unified technical standard, industrial system and management system, it is difficult to realize the interconnected operation of multiple energy sources. Generally, the tilting experimental machine mobilized by the source load storage association has three force measuring ranges for interaction and real-time interactive sharing of information

at the level of economic policy, there is no energy storage electricity price system in terms of price system. Energy storage is the buffer, aggregator and stabilizer of the new generation power system, and is an important means to solve the problem of renewable energy consumption. However, at present, the cost of energy storage is high. At this stage, China has not issued energy storage electricity price and subsidy policy. It is difficult to make up for the high cost of energy storage only by relying on the peak valley price difference. The return on investment is poor, which seriously restricts the large-scale development of energy storage

in terms of price mechanism, price signal transmission and fairness need to be strengthened. A scientific and reasonable price mechanism is the key to ensure the effective operation of the power market mechanism, give full play to the role of the optimal allocation of market resources, and guide the healthy, orderly and benign development of the new generation of power system. The current energy prices in China are mainly set by the government, which can not fully reflect the market signals and ensure the fairness of prices. At the same time, there is a lack of value conversion media and mechanisms among various types of energy, and a multi energy price linkage mechanism needs to be established

in terms of benefit evaluation mechanism, the investment income evaluation system applicable to the construction of new generation power system needs to be established. As an important energy transmission and configuration platform, the whole process of the new generation of power system related industries from investment and construction to production and operation will bring significant benefits to the national economy, energy production and utilization mode, environment, etc. However, at the initial stage of construction, the economic benefits of the new generation power system are limited, and it is very easy for the investors to lack the enthusiasm to participate. Therefore, it is necessary for the relevant national departments to build a new generation power system investment income evaluation mechanism from the perspective of national development strategy, so as to guide the orderly construction of the new generation power system

fiscal and tax policies

at the financial support level, China currently has limited financial support and financial incentives in the research and development of key technologies of the new generation power system, major project demonstration pilot, industrial development and promotion and application of new technologies, and the measures are single. At the same time, there are still a large number of subsidies that are not in place

at the level of tax preference, in order to promote the development of the new generation power system in the direction of scale, industrialization and intensification, the central and local governments should further optimize the tax service environment, actively implement the tax preference policies, and promote the rapid development of the new generation power system through tax reduction and exemption for the relevant products, technologies and equipment of the new generation power system with good economic, social and environmental benefits

investment and financing policy level

at present, in the field of power system, the investment and financing mode with the government as the "center" occupies a dominant position, the investment channel is single, and the participation of different attribute capital, different channel funds and different types of investment and financing projects in the construction of the new generation power system is insufficient. The financial policy system needs to be innovated to provide a perfect financing channel for the scientific and technological innovation of the relevant industries of the new generation power system, To provide financial instruments and financial system support for avoiding and resolving innovation risks

at the level of regulatory mechanism

first, China mainly adopts administrative means for energy, uses few economic and legal means, has a strong color of industry management, and lags behind in energy policy and planning. The competent authorities pay more attention to intervening in the behavior of microeconomic entities through investment project approval, price setting and production scale control, and the lack of government supervision is prominent

second, "open sharing" is one of the remarkable features of the new generation power system. Under the trend of deep integration of energy and information in the future, energy data security needs a perfect guarantee mechanism. However, China's current regulatory mechanism on energy information and data needs to be established, and the problem of data security management is prominent

policy recommendations for the construction of new generation power system

in order to guide and ensure the construction of new generation power system, this paper puts forward policy recommendations for the construction of new generation power system from the two dimensions of short-term landing policy and medium and long-term strategic policy based on the principle of operability, taking into account the long-term and landing of problems, and combining the near and far

recent policy recommendations

it is suggested to make an overall plan for the construction and development of the new generation energy system, carry out the top-level design of the new generation power system, prepare the sub plan for the development of the new generation power system and related industries, and formulate the specification and standard system of the new generation power system according to the energy transformation objectives of the energy production and consumption revolution strategy (2016-2030)

carry out the architecture design of China's new generation power system. It is suggested that based on the characteristics of China's energy industry and the current development level of information, control and management systems, and in combination with the development trend of relevant technologies in the future, we should carry out the architecture design of China's new generation power system, define the key business areas and supporting technology areas for the construction of the new generation power system, so as to ensure that the new generation power system can meet the planning, construction, coordinated operation and information and data sharing needs of various energy networks, Effectively solve the practical problems in China's energy transformation and power system development

overall planning for the development of the new generation power system. It is suggested to introduce the concept of comprehensive resource planning, strengthen the coordinated planning of source, load and storage and the overall planning of multiple energy sources, comprehensively consider the planning, construction, transformation and technological upgrading of different primary and secondary energy supply networks, prepare the development plan of the new generation power system and its related industries, and clarify the overall supply-demand balance and structural optimization of multiple energy sources, energy flow direction, supply-demand balance in different regions and the construction of energy transportation system, So as to achieve the goals of various energy network integration, comprehensive energy utilization and energy structure adjustment

formulate relevant specifications and standard systems for the new generation power system. It is suggested that national 3. When clamping, the front and back of the samples should be installed in parallel as far as possible to develop a unified specification and standard system for the new generation power system, organize forces from all aspects to focus on scientific research, rely on the existing standard systems of power supply, electricity, energy storage and other related industries, and integrate them into the framework of China's new generation power system system after improvement and integration, so as to finally form a complete new generation power system specification and standard system, It provides an important guarantee for the multi energy interconnection and real-time information exchange of the new generation power system

second, build a multi-level coordinated power market mechanism

it is suggested that China, on the basis of the existing power market, accelerate the construction of provincial spot market, auxiliary service market and inter provincial power trading market, gradually form a market-based power and electricity balance mechanism with medium and long-term trading as the main, supplemented by spot trading market, supplemented by auxiliary services and capacity market, and build a power market mechanism with multi time scales, multi trading varieties and multi trading ranges

build a national unified power market with coordinated operation within and between provinces. It is suggested that on the basis of the current electricity market mechanism in China, which is dominated by intra provincial transactions and supplemented by inter provincial fixed-point transactions, the construction of inter provincial and inter regional electricity trading market should be accelerated, and the intra provincial and inter provincial electricity trading market should be established from the aspects of trading sequence, trading space, trading varieties, trading subjects, etc
