新能源为主体电力系统的需求侧资源利用关键技术及展望

Key Technologies and Prospects of Demand-side Resource Utilization for Power Systems Dominated by Renewable Energy

能源转型背景下的电力清洁低碳化将推动传统电力系统向以新能源为主体的新型电力系统发展。新型电力系统中的电力供应保障和安全稳定运行能力将受到高比例新能源的极大挑战,传统电力系统运行模式下单靠电源侧资源已无法满足安全稳定且经济高效的电力供应要求,必须充分挖掘需求侧资源的潜力,由"源随荷动"向"源荷互动"转变。文中首先阐述了新型电力系统面临的电力安全可靠经济供应新形势,其次研究分析了国内外需求侧资源利用实践,在此基础上,提出了面向新型电力系统的需求侧资源利用关键技术,并从资源开发重点、运行管理、市场机制、政策措施、商业模式5个方面对中国新型电力系统需求侧资源利用进行了展望。

In the background of energy transition,clean and low-carbon power systems will promote the development of traditional power systems to new power systems dominated by renewable energy.The power supply guarantee and safe and stable operation ability of the new power systems will be greatly challenged by the high proportion of renewable energy.The traditional power system operation mode solely relying on the power-side resources cannot meet the requirements of safe,stable and cost-effective power supply.The potential of demand-side resources must be fully tapped to transit from"source follows load"to"source interacts with load".In this paper,firstly,the new situation of safe,reliable and economic power supply faced by the new power systems is described.Secondly,the practice of demand-side resource utilization at home and abroad is studied and analyzed.On this basis,the key technologies of demand-side resource utilization for the new power systems are put forward.The demand-side resource utilization of China’s new power systems is prospected from five aspects of resource development focus,operation management,market mechanism,policy measures,and business model.
