Planning Methods for Transnationally Interconnected Power Systems under the Background of Clean Low-Carbon Development

Under the macro background of clean and low-carbon development for addressing global climate change, the current research on transnationally interconnected power systems has certain deficiencies in terms of geographic scope, time span, and multi-level coordination. We propose an orderly and coordinated framework for planning and research of transnationally interconnected power system, and introduces the key technical models such as scenario building, generation-grid collaborative planning, and environmental climate-economic-social benefit analysis. An overall work process is designed based on the “ work system” and “support system”. Taking the temperature limit of the Paris Agreement as the objective, a scenario analysis is carried out, including global power demand, power supply mix, energy flow and other issues, and the comprehensive benefits are evaluated. Finally, the planning research methods are summarized and relevant suggestions are proposed.
