面向新型电力系统的电氢耦合多时空尺度规划:China-MSTPEHC综合规划模型OA

To quantify the long-term impact of electric-hydrogen coupling on new-type power systems in promoting renewable energy consumption and low-carbon transition,this paper proposes a China multi-spatial and temporal planning model of electric-hydrogen coupling(China-MSTPEHC)model with scenario setting,configuration and operation optimization,and benefit evaluation.It integrates seven major power grid regions and combines the annual capacity configuration with hourly operation simulation.The key findings are as follows:1)By 2060,China's electrolysis capacity will form a spatial pattern of hydrogen production from onshore wind and solar in northern grid regions,hydropower in southwestern grid regions,and offshore wind in eastern grid regions.2)Inter-regional hydrogen pipelines will be planned by 2030.By 2060,three main pipelines("North China-East China","North China-Central China",and"Northwest China-Southwest China")will emerge,forming a spatial pattern of"west-to-east and north-to-south hydrogen transport".3)Electric-hydrogen coupling can increase renewable energy capacity,decrease thermal power capacity,and reduce total costs.
