摘　　要：光热发电具有清洁、稳定和可再生的特点,并可深度参与电网调峰调频以提升电力系统灵活性,因而受到了世界各国的广泛关注。然而,光热发电系统在运行过程中受天气情况等多种随机扰动的影响,且本身存在非线性、大迟延和强耦合的特性以及多种运行模式,亟需研究保障该系统安全、稳定和经济运行的技术。以槽式和塔式光热发电系统为研究重点。首先,梳理了以能效和经济性优化为目标的稳态建模,以及面向控制的动态建模工作。接着,总结了调度和参数优化技术。最后,综述了槽式光热发电系统聚光器追踪控制、集热场控制和整体协调控制,以及塔式光热发电系统定日镜场控制和吸热器温度控制等进展情况。此外,指出了目前尚待解决的主要问题,并对未来研究方向进行了展望、提出了可能的研究思路。该研究可为光热发电系统优化运行技术的进一步发展提供参考。Concentrated solar power is characterized by cleanness,stability and renewability,and can deeply participate in grid peak shifting and frequency regulation to enhance the flexibility of the power system,which has received extensive attention from countries all over the world.However,the concentrated solar power system is affected by various random perturbations such as weather conditions,etc.,during operation,and itself has the characteristics of nonlinearity,large delay and strong coupling as well as a variety of operation modes,so it is urgent to study the technologies to ensure the system's safe,stable and economic operation.The research focuses on trough-type and tower-type concentrated solar power systems.Firstly,steady-state modeling aiming at energy efficiency and economy optimization,and control-oriented dynamic modeling work are sorted out.Then,scheduling and parameter optimization techniques are summarized.Finally,the progress of concentrator tracking control,collector field control and overall coordinated control for trough-type concentrated solar power system,as well as heliostat field control and heat absorber temperature control for tower-type concentrated solar power systems,etc.,are summarized.In addition,the main problems which still to be solved are pointed out,and the future research directions are envisioned,and possible research ideas are proposed.This study can provide a reference for the further development on optimized operation technology of concentrated solar power system.
