水电支撑新型电力系统灵活性研究进展、挑战与展望OA北大核心CSTPCD
Progress,Challenges and Prospects of Research on Hydropower Supporting the Flexibility of New Power Systems
风光新能源发电的中长期季节性波动、短期随机性和间歇性波动使得新型电力系统面临巨大的灵活性需求和季节性保供挑战.为此,我国工业界和学术界提出"水电角色重塑和功能再造"的概念,目的是充分发挥我国独一无二的水电资源优势,重塑水电灵活性资源角色,支撑新能源大规模开发利用.这一理念和相关理论技术问题,受到政府部门、电力企业的充分重视和众多学者的广泛研究,且仍在发展之中.为了更好地总结和展望相关研究成果,该文归纳我国水电灵活性的重要现实基础,并从流域水风光综合基地、省级电网、区域电网 3 个层级,综述水电支撑新型电力系统灵活性的研究进展.在此基础之上,从理论方法和工程应用 2 个方面提炼亟待突破的关键挑战,并展望相关解决思路.
The seasonal fluctuation,short-term intermittency and randomness of new energy will lead to severe challenges of flexibility demand and seasonal power supply in new power systems.Chinese industry and academia have developed the concept of"role remaking and functions reinventing of conventional hydropower plants",with the aim of giving full play to China's unique hydropower resource advantages and remaking the hydropower plants as flexibility resources to support the new energy development.This concept has received full attentions by government departments and power companies.Its related theoretical issues have been extensively researched by many scholars,and are still under development.In order to better review and prospect the relevant research results,this paper summarizes the important practical basis for taping and utilizing the hydropower flexibility potential in China.The research results on hydropower supporting the flexibility demands of new power systems are reviewed at three scheduling levels of river basin hydro-wind-solar integrated energy bases,provincial power grid and regional power grid.On this basis,challenges in theoretical research and engineering applications for utilizing hydropower flexibility are extracted.Preliminary solutions to the challenges are also discussed.
