In order to implement the spirit of the 20th CPC National Congress, accelerate the planning and construction of a new energy system, the implementation of the "Guiding Opinions on Accelerating the Development of New Energy Storage" (Development and Reform Energy Regulation 〔2021〕 No. 1051), "New Energy Storage Project Management Specification (Provisional)" (National Energy Development Science and Technology Regulation 〔2021〕 No. 47), "Notice on the Further Promotion of the Participation of New Energy Storage in the Electricity Market and Scheduling" (Development and Reform Office Operation 〔2022〕 No. 475). Reform Office Operation [2022] No. 475), standardize the management of new energy storage grid access, optimize the scheduling and operation mechanism, give full play to the role of new energy storage to support the construction of a new type of power system, is now on the relevant matters as follows.
I. General requirements
(a) accurately grasp the new energy storage function positioning. New energy storage refers to the pumped storage, to the output of electricity as the main form of energy storage technology, and provide services to the outside world, with a short construction period, flexible layout, fast response speed and other advantages, can be played in the operation of the power system peak shifting, frequency regulation, voltage regulation, standby, black start, inertia response and other functions, is to build a new type of power system is an important support technology. With the rapid growth of installed capacity, the role of new energy storage in promoting new energy development and consumption and safe and stable operation of the power system is gradually emerging. Combined with the new energy storage function positioning and marketization requirements, it should further regulate the new energy storage grid management, continue to improve the new energy storage scheduling mechanism, ensure the reasonable and efficient use of new energy storage, and strongly support the construction of new power systems.
(b) Clarify the scope of new energy storage that is subject to the dispatch of the power system. Access to the power system and signed scheduling agreement of the new energy storage, can be divided into scheduling call new energy storage and power station self-use of new energy storage two categories. Dispatching new energy storage refers to the new energy storage with independent metering devices and operated in accordance with the market clearing results or the instructions of the power scheduling organization, including independent energy storage power stations, new energy distribution energy storage with conditions for independent operation, etc.; the new energy storage for power station self-use refers to the new energy storage operated in conjunction with power generating enterprises, users, etc. and controlled by power generating enterprises, users, etc. according to their own needs, including new energy storage not operated independently. The new energy storage for power station's own use refers to the new energy storage that operates jointly with power generation enterprises and is controlled by power generation enterprises and users according to their own needs, including the new energy storage that is not operated independently, the thermal power joint frequency regulation energy storage, and the user-side energy storage that has the ability to accept dispatching instructions.
II. Strengthening new energy storage grid integration and dispatch operation management
(c) Standardize the management of grid access for new types of energy storage. Grid enterprises and power scheduling agencies shall formulate new energy storage grid rules and guidelines for grid connection services, etc., to clarify the grid connection process, relevant standards and requirements for grid-related tests. Power scheduling agencies in accordance with the principle of equality and mutual benefit, consensus and ensure the safe operation of the power system, the organization of new energy storage and grid acceptance and sign the grid scheduling agreement, the new energy storage should be connected to the grid within a specified period of time to complete all the network-related tests.
