(Draft for comments)


In order to thoroughly implement the spirit of the 20th National Congress of the Communist Party of China, accelerate the planning and construction of new energy systems, and implement the "Guiding Opinions on Accelerating the Development of New Energy Storage" (Fagai Energy [2021] No. 1051) and "New Energy Storage Project Management Specifications (Interim)" "(Guoneng Science and Technology Regulations [2021] No. 47) "Notice on Further Promoting New Energy Storage's Participation in the Electricity Market and Dispatch Application" (National Development and Reform Office Operation [2022] No. 475) relevant requirements to standardize the grid connection of new energy storage management, optimize the dispatching operation mechanism, give full play to the role of new energy storage, and support the construction of a new power system. The relevant matters are hereby notified as follows.


1. Overall requirements


(1) Accurately grasp the positioning of new energy storage functions. New energy storage refers to energy storage technology that, in addition to pumped hydro energy storage, mainly outputs electricity and provides services to the outside world. It has the advantages of short construction period, flexible layout, and fast response speed. It can play a role in peak load regulation, Frequency regulation, voltage regulation, backup, black start, inertia response and other functions are key supporting technologies for building new power systems. With the rapid growth of installed capacity, the role of new energy storage in promoting the development and consumption of new energy and the safe and stable operation of power systems is gradually emerging. It is necessary to combine the positioning of new energy storage functions and market requirements to further standardize the management of new energy storage grid connections, continue to improve the new energy storage dispatching mechanism, ensure the rational and efficient use of new energy storage, and effectively support the construction of new power systems.


(2) Clearly accept the scope of new energy storage for power system dispatching. New energy storage power stations that are connected to the power system and sign a dispatch agreement can be divided into two categories: new energy storage for dispatching and new energy storage for the power station's own use. Dispatching and calling new energy storage refers to new energy storage power stations that have independent metering devices and operate in accordance with market clearing results or instructions from the power dispatching agency, including independent energy storage power stations, new energy-equipped energy storage stations that are qualified to operate independently, etc.; the power station is used for its own use New energy storage refers to new energy storage power stations that operate jointly with power generation companies, users, etc., and are controlled by power generation companies, users, etc. according to their own needs, including new energy-equipped energy storage that does not operate independently, thermal power joint frequency modulation energy storage, signed dispatching User-side energy storage that has protocols and has the ability to accept dispatching instructions.
