2012年中国的用电量为4966太瓦时，是世界上最大的电力消费国。低碳电力是其可持续发展的关键问题之一。综合资源战略规划（IRSP）是在供电侧实施需求侧管理（DSM）和电力规划的有用工具。然而，在IRSP中没有考虑到快速增长的跨区域传输的互联智能电网的作用。因此，为了将更多的可再生能源发电并入电网，实施更多的DSM项目，本文提出了具有互联智能电网的IRSP模型，称为IRSP-sgs （IRSP智能电网）模型。利用IRSP-sgs模型预测了到2025年中国跨区域输电对低碳电力影响的两种情景。结果表明，跨区域输电增强情景下，2013-2025年可减少发电量784.38 TWh，减少二氧化碳排放99957万吨，因为多区域电力运行可将488.30 TWh以上的可再生能源并网发电，并实施更多的DSM项目来替代发电。此外，它也为提高电力系统的稳定运行提供了巨大的机会。
The China's electricity consumption was 4966 TWh in 2012, which is the world top electricity consumer. The low carbon electricity is one of the key issues of its sustainable development. IRSP (integrated resource strategic planning) is a useful tool to implement DSM (demand side management) and power planning on the supply side. However, the role of interconnected smart grids with fast growing cross-region transmission is not considered in the IRSP. Therefore, the paper proposes the model of IRSP with interconnected smart grids to integrate more renewable power generation to the grids and implement more DSM projects, which is called as IRSP-sgs (IRSP smart grids) model. Two scenarios are projected to study the impact of cross-region transmission on low carbon electricity by using the IRSP-sgs model until 2025 in China. Results show that the scenario with enhanced cross-region transmission helps to reduce electricity generation by 784.38 TWh and reduce CO2emission by 999.57 million tons during 2013–2025, since the multi-regional power operation can integrate more than 488.30 TWh renewable generation into the grids and implement more DSM projects to substitute generation. In addition, it also provides tremendous opportunities to improve the stable operation of the power system.
