摘要
在“双碳”目标下,新能源迎来新的、跨越式发展对电力系统灵活性提出更高要求。光热发电拥有与常规火电机组相媲美的调节特性,可快速深度参与电网调峰调频,提升电力系统灵活性,是极具发展前景的可再生能源发电技术。介绍了光热发电技术运行原理及系统结构,总结归纳了各类发电技术的优缺点、分析了光热发电技术的研究进展。在此基础上,结合光热发电的发展现状和需求,对光热发电还需关注的问题与未来光热发电技术的发展方向进行了探讨。
Under the "dual carbon" target, new energy ushers in a leapfrog development,which makes an higher requirement for power system flexibility. The regulation capacity of concentrating solar power(CSP)plants can rival that of conventional thermal units. CSP plants can participate in peak load and frequency regulations timely and deeply, which improves the flexibility of the power system. Thus,CSP is a promising renewable energy generation technology. Based on the introduction on the operation principle and structure of a CSP plant, the advantages,disadvantages and research progress of various CSP technologies are analyzed. The problems and development direction of CSP technology are discussed based on the status quo and demand of CSP.
