Under the guidance of carbon peak and carbon neutrality targets, the proportion of new energy installed capacity has rapidly increased, and new grid connected entities such as new energy storage, virtual power plants, and distributed smart grids have emerged widely. Significant progress has been made in the construction of new power systems. However, due to the scattered regulations and standards related to the safety management of new energy and new grid connected entities, some new grid connected entities have not been included in the unified dispatch, resulting in a partial vacuum in the safety management of the grid and affecting the safe and stable operation of the power system. In order to thoroughly implement the new energy security strategy of "four revolutions and one cooperation", implement the "Guiding Opinions of the National Development and Reform Commission and the National Energy Administration on Strengthening the Stability of the Power System under the New Situation" and the "Guiding Opinions of the National Development and Reform Commission and the National Energy Administration on Strengthening the Construction of Peak shaving, Energy Storage and Intelligent Dispatch Capacity of the Power Grid", further enhance the network security capabilities of new energy and new grid connected entities, and strengthen the rigid implementation of existing safety management norms and standards, the relevant matters are hereby notified as follows.

1、 Accurately grasp the overall requirements of network security management work

（1） We attach great importance to the management of cyber security. Strengthening the safety management of new energy and new grid connected entities, ensuring their safe and stable operation, is the foundation and prerequisite for serving the high-quality development of the new power system. Once a grid connected entity experiences a safety accident, it not only damages current interests but also has adverse effects on the long-term development of the industry. Each unit should closely adhere to the goals of energy transformation and power supply guarantee under the new situation, innovate safety management models with a high sense of responsibility and mission, effectively control safety risks, and resolutely prevent grid connected safety accidents from occurring.

（2） Scientifically define the scope of network security management. The dispatched agencies of the National Energy Administration shall, in conjunction with local power management departments, comprehensively consider the actual situation such as system safety needs, technical and economic feasibility, and the capacity of grid connected entities. Based on the types, capacity scales, access voltage levels, and system operation characteristics of new energy and new grid connected entities, scientifically define the scope of network related safety management for new energy and new grid connected entities within their jurisdiction, and effectively manage those that must be managed. For existing new energy and new grid connected entities that have been included in the scope of network security management but do not currently meet the requirements of network management, the dispatched agencies of the National Energy Administration should work with local power management departments to scientifically formulate renovation plans and steadily promote them.

（3） Consolidate the responsibilities of all parties involved in network security management. The power dispatch agency should strengthen the unified dispatch and management of new energy and new grid connected entities included in the scope of grid related safety management, and carry out technical supervision of grid related secondary systems and monitoring systems in accordance with relevant laws, regulations, standards and specifications. Power grid enterprises should strengthen the risk control of power grid safety and provide guarantees for the safe grid connection of grid connected entities. Owners (units) of new energy and new grid connected entities included in the scope of network security management must strictly fulfill their main responsibilities, accept unified dispatch by power dispatching agencies, implement network security management rules and regulations, and meet the needs of system security and stable operation.

Before grid connection, the power dispatching agency shall strictly review the performance type test reports provided by the grid connected entities included in the scope of grid safety management. The reports shall be issued by a third-party organization with CNAS/CMA qualifications (recognized by the China National Accreditation Service for Conformity Assessment or China Metrology Certification) or equivalent qualifications, and can only be connected to the grid after approval from the review; After grid connection, the power dispatching agency should strengthen the evaluation of grid related performance during operation, timely propose improvement requirements, and ensure stable grid related performance.

（5） Promote friendly grid connection among grid connected entities. Owners (units) of new energy and new grid connected entities should organize and implement engineering project construction in accordance with the requirements of the "Guidelines for Safety and Stability of Power Systems" (GB 38755-2019), "Technical Guidelines for Grid Source Coordination of Power Systems" (GB/T 40594-2021), as well as national and industry standards related to wind power, photovoltaics, and energy storage, to ensure that secondary system configurations such as relay protection, safety and stability control devices, and communication equipment meet the requirements and avoid "network connection with faults". Among them, centralized new energy sources that gather remotely (such as large bases) should have support capabilities such as rapid voltage regulation and suppression of broadband oscillations. If necessary, devices such as phase-shifting cameras should be installed to prevent large-scale disconnection.

（6） Promote technological innovation and revise standards for internet related technologies. Actively carry out research, verification, promotion and application of new energy and new grid connected technologies, and enhance their safety substitution capabilities. Promote the revision of grid connection standards for new technologies and equipment, and gradually build grid related safety performance that is compatible with the development of new power systems.
