Strategies and system architecture for the ICT-Energy convergence by Peng GAO, Ziyu XIAO, Sheng ZHANG

“…The global demand for green and low-carbon development was analyzed, highlighting that despite sustained increases in global carbon emissions, current efforts fall short of achieving the temperature targets set forth by the Paris Agreement.Green and low-carbon development has thus emerged as a universal consensus and a prevailing trend worldwide.China’s current energy situation and relevant policies were further described, asserting that the ICT-Energy convergence is an inevitable path for future societal digitalization and low-carbonization.Then, the objectives and system architecture of ICT-Energy convergence were proposed.Central to the role of ICT Systems, the architecture embodies three core functionalities, realizing efficient management across all segments of the energy sector through intelligent control, fostering cross-domain synergy between ICT and energy networks and empowering various industries.An exploration of the system synergy mechanisms was conducted within the ICT-Energy converged architecture, and implementation pathways and strategic recommendations for ICT-Energy convergence were outlined.…”
