Recently, the National Development and Reform Commission and the National Energy Administration issued the "Guiding Opinions on Promoting the Integration of Power Sources, Networks and Loads and Storage and the Development of Multi-energy Complementarity" with a validity period of 5 years.

      According to the document, in terms of implementing the main responsibilities, the provincial energy authorities are responsible for organizing and promoting the integration of source, grid and load storage and multi-energy complementation projects. They should actively organize related power supply, power grid, and power consumption enterprises in conjunction with agencies dispatched by the National Energy Administration. And consulting agencies carry out the classification organization, research and demonstration, evaluation and selection, preparation and submission, construction and implementation of projects and implementation plans. For cross-provincial development and consumption projects, the relevant energy authority shall, on the basis of conforming to the overall national energy pattern and power flow, reach a preliminary intention after full consultation, and organize the implementation plan research and report to the National Energy Director in conjunction with the agency sent by the National Energy Administration. Department. All localities must strictly implement the national power development plan, resolutely prevent the opportunity to expand the scale of fossil power sources, aggravate the contradiction between power supply and demand and the consumption of renewable energy, and ensure that it is in line with the green and low-carbon development direction.

      The implementation path of grid-load-storage integration will be through optimizing and integrating local power, grid, and load-side resources, supported by advanced technological breakthroughs and institutional innovations, and exploring the construction of a new power system development path with a high degree of integration of source, grid, load and storage, which mainly includes Specific models such as "source-network-load-storage integration" at the regional (provincial) level, city (county) level, and park (residential area) level.

      Multi-energy complementary implementation path: Utilize existing conventional power sources, reasonably configure energy storage, coordinate various power planning, design, construction, and operation, prioritize the development of new energy, actively implement the inventory "wind, solar, water, and fire storage integration" upgrade, and steadily promote the incremental "wind and solar" "Integration of water (storage)", exploring incremental "integration of wind, solar, and storage", and strictly controlling the incremental "integration of wind, solar, and fire (storage)."

      The document also pointed out that the promotion of multi-energy complementarity will increase the level of renewable energy consumption.

      Integration of wind, wind and storage. For stock new energy projects, combining new energy characteristics and receiving end system consumption space, research and demonstrate the necessity and feasibility of increasing energy storage facilities. For the integration of incremental wind and solar storage, optimize the scale of supporting energy storage, give full play to the functions of peak shaving and frequency modulation of supporting energy storage, minimize the integrated power generation cost of wind and solar storage, and enhance comprehensive competitiveness.

      Integration of scenery and water (storage). For existing hydropower projects, combining the output characteristics of the sending-end hydropower, the characteristics of new energy, and the absorption space of the receiving-end system, research and demonstrate the necessity and feasibility of prioritizing the use of hydropower regulation performance to absorb nearby wind and wind power and increasing energy storage facilities according to local conditions. Encourage Optimize the output characteristics through the construction of the leading power station, and realize the nearest bundling. For the integration of incremental wind, solar, and water (storage), in accordance with relevant national and local environmental protection policies, ecological red lines, and water resources utilization policy requirements, strictly control the scale of small and medium hydropower construction, and use large and medium hydropower as the basis to coordinate the collection of new energy power at the sending end. Optimize the scale of supporting energy storage.

      Integration of scenery and fire (storage). For existing coal-fired power projects, priority is given to improving adjustment capabilities through flexible transformation, combining the development conditions and output characteristics of new energy sources in the vicinity of the sending end, and the receiving end system consumption space, and striving to expand the scale of nearby bundled new energy power. For incremental base-based development and delivery projects, based on the transmission capacity of the power grid, rationally utilize the complementary advantages of new energy regions, prioritize the collection of new energy power in the nearby area, and optimize the scale of supporting energy storage; make full use of the power (heat) supply Coal power projects in the vicinity of active service and included in the national power development plan to strictly control the demand for new coal power; in principle, the proportion of renewable energy in the transmission channel is not less than 50%, and priority is given to planning and building a channel with a higher proportion; implementation of the country And local related environmental protection policies, ecological red lines, water resources utilization and other policy requirements, and obtain planning environmental assessment and planning water resources demonstration review opinions in accordance with regulations. For incremental in-situ development and consumption projects, on the basis of fully evaluating local resource conditions and consumption capacity, priority is given to the use of new energy power.

      The document pointed out that in terms of improving policies and measures, on the basis of organizing evaluations and demonstrations and fully soliciting opinions from agencies dispatched by the National Energy Administration, sending and receiving end energy authorities, and power companies, in accordance with the principle of "pilots first, gradually popularized", through the national power development plan formulation , Annual fine-tuning, mid-term rolling adjustment, and prioritize qualified projects into the national power development plan.

      In addition, in terms of improving support policies, the document pointed out that new energy power generation projects in source-network-load-storage integration and multi-energy complementary projects should implement the national renewable energy power generation project management policy, and coordinate in the national and local renewable energy planning implementation plans. Arrangements: Encourage qualified regions to organize and promote the construction of relevant projects in a unified manner, and support participation in cross-provincial power market-oriented transactions, incremental power distribution reforms, and distributed power-generation market-oriented transactions.
