Specifically, the State Grid meets the grid connection needs of 401 centralized and 280,000 distributed new energy power generation projects; earnestly implements the national early warning document requirements, and 88% of the newly installed capacity is concentrated in basically unlimited power (the utilization rate is higher than 95% ) Provinces and regions; completed and put into operation Zhundong-South Anhui, Shanghai Temple-Shandong, Zhangbei-Xiongan, Qinghai-Henan and other UHV AC and DC projects; through the installation of converter stations in converter stations, the promotion of wind farm withstand voltage transformation, etc. Measures to further increase the DC transmission capacity of Qishao, Lugu, Lingshao, and Zhaoyi to 5 million, 5.6 million, 7.2 million, and 4 million kilowatts; implement an action plan to increase the utilization rate of transmission channels, and 11 UHV DCs in the State Grid business area The average utilization hours increased by 397 hours year-on-year; 15 key projects including the 750kV third channel in Northwest China were completed and put into production, and the delivery capacity increased by more than 8.2 million kilowatts.

In terms of dispatching operation, State Grid promoted the construction of auxiliary service market, 4 regions and 12 provincial-level grid peak shaving auxiliary service markets were operated, and the conventional power peak shaving was driven by the market mechanism throughout the year to consume 12.4 billion kwh of new energy; Continuously optimize the regional and cross-regional spinning reserve sharing mechanism, reduce thermal power reserve by 4 million and 1.27 million kilowatts in the northwest and northeast respectively; tap the potential of peak shaving, make full use of pumped storage power stations, and promote the completion of the flexible transformation of thermal power by 57.75 million kilowatts; Diversified coordinated dispatching and control, improved new energy forecasting technology, and realized all distributed power sources are considerable.

At the same time, the company also gave full play to the role of the market in optimizing the allocation of resources, and continued to expand the scale of inter-provincial transactions. The annual new energy inter-provincial transaction power was 88 billion kWh, a year-on-year increase of 22%, of which the new energy cross-regional spot transaction power was 5 billion kWh. ; Promote the implementation of electricity demand response, and completed a total of 57.1 billion kilowatt-hours of new energy market-oriented transactions in the province throughout the year, an increase of 34% year-on-year; completed the replacement of 180.2 billion kilowatt-hours of electricity throughout the year.

In addition, State Grid has also innovated the construction of a new energy cloud, building a new energy open service system of "horizontal coordination, vertical connection" and "full link, full connection, full coverage, full ecology, and full scenario", and pilot projects in 13 provincial companies .

This year will complete the new energy cloud full online line

Build a win-win cooperation ecosystem

The "New Energy Development Report" revealed that in order to ensure the achievement of the full-year development goal and the goal of over 95% of the new energy utilization rate, and to promote the sustainable and healthy development of new energy in the "14th Five-Year Plan" and longer in the future, the State Grid Research and Development Ten new measures to promote the development of new energy in 2020, including realizing the new development goals for the whole year, making every effort to provide grid-connected services, strengthening grid engineering construction, promoting peak-shaving capacity building, strengthening unified dispatching of the entire network, strengthening new energy power prediction, Expand the scale of market transactions, effectively implement the consumption guarantee mechanism, strengthen the management of new energy subsidies, and complete the full online launch of the new energy cloud.

Specifically, the State Grid will optimize the layout and timing of new grid-connected installations, deeply explore the acceptance capacity and consumption space, and increase the proportion of power generation to more than 10%; accelerate the Zhangbei-Xiongan UHV exchanges, Qinghai-Henan Special The construction of key projects such as high-voltage direct current and Zhangbei flexible direct current will ensure that it is put into operation on schedule within the year; speed up the construction of supporting grid projects to ensure that new projects are connected to the grid on schedule; speed up the construction of pumped storage power stations; actively cooperate with the flexible transformation of thermal power units.

In addition, State Grid will complete the full online new energy cloud, create an open, transparent, convenient and efficient new energy digital economy platform, and provide users with a one-stop shop for installation, planning, design, construction, grid connection, operation, trading, and settlement. "Online service, comprehensively improve work efficiency and service level, build a new energy ecosystem of win-win cooperation, and drive the common development of the upstream and downstream of the industrial chain.

State Grid launched an initiative to the society

Promote high-quality development of new energy

The "New Energy Development Report" pointed out that the high-quality development of new energy is inseparable from the care and care of the whole society and requires the scientific guidance of the government and the joint efforts of the whole industry. In this regard, the State Grid proposes: to strengthen top-level design and strengthen planning and coordination. Scientifically and reasonably determine the development goals and development timing of renewable energy, strengthen the effective connection between the state and the local, power supply and grid, new energy and conventional energy and other levels and types of planning, and ensure that the planning objectives, tasks and measures are compatible with each other. Improve systems and mechanisms to promote efficient use. In conjunction with the market-oriented reform process, scientifically and rationally determine the number of guarantee utilization hours in various regions, and strengthen the connection between full-amount guarantee purchases and market-oriented consumption. Improve the auxiliary service market and establish a system for new energy power generation to participate in power spot market transactions.

At the same time, it is necessary to improve supporting policies to achieve sustainable development. Clarify the functional positioning of energy storage in the power system and the principles of energy storage configuration for new energy power stations, and provide policy support in terms of planning and construction, cost reduction, etc. Improve the demand-side response policy, increase the flexibility of power load resources, and actively respond to changes in new energy output. Increase scientific and technological innovation and improve technological level. Continue to carry out key technological innovations for new energy development, promote the construction of the energy Internet, improve the efficiency of the energy system, and build a clean, low-carbon, safe and efficient energy system. Improve the technical standards and engineering specifications for grid connection of new energy and distributed power sources, and improve the technical requirements for grid-related safety of new energy power generation.

In addition, the State Grid also proposes to jointly promote the construction of new energy clouds, strengthen the whole process and all links of new energy high-quality services through digital drive and integration innovation, build an internationally leading new energy digital economy platform with Chinese characteristics, and promote the high-quality development of the new energy industry .
