【摘要】 风电出力与负荷需求呈逆向分布是产生弃风的主要原因，而传统仅靠火电机组参与风电的调度，受制于火电机组爬坡能力不足、启停成本高等原因，不能满足系统的备用需求。为解决上述问题，提出了含光热、火电、风电系统的多源联合调度模型。利用出力灵活、含有大规模储热系统的光热电站为系统提供备用容量，与风电、火电共同参与系统调度，以传统火电机组与风电系统的调度模型作为对比。结果表明，所提调度策略能够在提高火电机组的利用效率和风电消纳水平的同时，降低系统运行成本。更多还原

【Abstract】 The wind power distribution antidromic to load demand is major cause for wind power abandonment. Due to the insufficient fast ramp-up ability of thermal power unit and high startup and shutdown cost, the traditional wind power distribution with thermal power unit cannot meet the backup requirement of power system. In order to solve the above problems, a multi-source joint dispatch model with solar thermal, thermal power, and wind power systems is proposed. The solar thermal power station with flexible output and large-scale thermal storage system is used to provide reserve capacity for the distribution with wind power and thermal power. Compared with traditional distribution model, the proposed dispatching strategy can improve the utilization efficiency of thermal power plants and the level of wind power consumption while reducing the operating cost of the system.更多还原
