August 2025 Preface China is accelerating the development of a clean, low-carbon, safe, reliable, cost-ef-ficient, demand-responsive, and flexible smart power system. As the future powersystem takes shape, the electric power industry is undergoing a structural transfor-mation, driven by significant changes across the supply side, the user side, grid archi-tecture, and operational models. On the supply side, renewable energy is increasinglybecoming the dominant source in terms of both installed capacity and power genera-tion. On the user side, a new trend of "integrated power generation and consumption"is emerging. The grid is evolving into a system centered on utility grids with diversegrid forms coexisting. Operationally, the traditional "load-based power generation"model is shifting toward "collaborative interaction among power generation, grid, load,and storage". The power communication network serves as a critical infrastructure that supports gridproduction control and enterprise management. It ensures the stable running of utilitygrids and active distribution network control, while interconnecting emerging powerentities and end-users nationwide. This connectivity is vital to the development of aunified national electricity market. The rapid evolution of the future power system isplacing increasingly complex and varied demands on the power communication net -work. The widespread adoption of AI foundation models, the development of digitaltwins for power grids, and the rise of intelligent computing centers are driving demandfor communication networks with ultra-high bandwidth, ultra-low latency, and highreliability. Meanwhile, the large-scale integration of distributed energy resources andbidirectional interaction with flexible loads call for broader communication coverage.Moreover, as power communication resources continue to scale, the need for smarterand more secure operational management becomes increasingly imperative. To meetthese challenges, the power communication network must undergo a comprehensiveupgradeto deliver ultra-reliable,high-capacity,ubiquitous coverage and light -ning-fast emergency response—while embedding intelligence across every layer ofoperations and maintenance (O&M). Only this level of advancement can provide therock-solid backbone needed to build and sustain the future power system. Thebrings together industry-wide expertise to chart a clear development path and providetop-level design and implementation guidance for tomorrow's grid communicationinfrastructure. By building a network featuring "intelligent and robust main network,medium-voltage integration, low-voltage transparency, high-speed and secure net -work, and space-ground integration", this initiative will offer critical support for China's"dual-carbon" goals (carbon peak and carbon neutrality) and accelerate the evolutionof the future power system.White Paper on Communication Target Networks of the Future Power System Contents Why the FuturePower SystemMatters01 ProspectsandInitiatives05 KeyCommunicationsTechnologies03 Why the Future PowerSystem Matters06 Planning and FutureDevelopment of TargetCommunicationNetworks for theFuture Power System04 78Advancing New TechnologyStandards79Building Against a Roadmap80Achieving Desired Outcomes82Afterword 28Classification of Technologiesin Power Communication Networks30Technology Trends in PowerCommunication Networks32Transmission Network Technology36Data Network Technology38Remote Communication AccessTechnology44Local Communication AccessTechnology46Satellite CommunicationTechnology49Communication SecurityTechnology Challenges inPowerCommunicationNetworks02 525456586274VisionArchitectureEvolutionSystemDirections and PrioritiesOutlook 01 Why the FuturePower System Matters Why the Future Power System Matters Why the Future PowerSystem Matters Facilitating "Dual Carbon" Goals The development of large-scale renewable energy sources, such as wind and photovoltaic power, isessential to progressively replace traditional fossil fuel-based generation and achieve the transition toa clean and low-carbon energy structure. Power System Development Currently, China's power system ranksNo. 1in the worldin terms of total installedcapacity, non-fossil energy installed capacity,long-distance transmission capacity, andpower grid scale. Ensuring Energy Security External dependence is reduced to achieve energy security and sustainable development. ! Addressing the Challenges of Power Transition Challenges Posedby New Energy Flexibility and stability are enhanced and resource allocation is optimized to fully improve the power systemefficiency. As the penetration rate of new energycontinues to increase, its intermittent,stochastic, and volatile natureimposeshigher requirements on the powersystem's flexibility and rapidregulation capabilities.
