【摘要】：考虑风电日波动性对常规机组启停的影响,为准确刻画系统运行经济性与风电消纳能力的关系,设计了风电最大出力模式、经济运行模式和运行成本控制模式3种风储联合发电系统日前发电计划模式,提出了不同模式的两阶段优化模型及快速求解算法。第1阶段通过储能系统和常规机组协调调度,实现经济性最优或弃风量最小的目标,第2阶段优化则按照经济调度和"三公"调度的原则分配常规机组和风电场的有功出力。提出快速算法削减了模型的寻优空间,大幅提高了优化模型的求解效率。基于IEEE 30节点系统进行仿真分析,验证了所述模型和算法的优越性。
[Abstract]:Considering the influence of daily fluctuation of wind power on the start-up and shutdown of conventional units, the maximum output mode of wind power is designed in order to accurately describe the relationship between the operating economy of the system and the capacity of wind power absorption. Economic operation mode and operation cost control mode three kinds of pre-day generation planning modes of wind storage combined generation system are presented. The two-stage optimization model of different modes and the fast solving algorithm are proposed. In the first stage, the energy storage system is coordinated with the conventional units to achieve the goal of minimum economic optimal or abandoned air volume. In the second stage, the active power output of conventional units and wind farms is allocated according to the principles of economic dispatch and "Sangong" dispatching. A fast algorithm is proposed to reduce the optimization space of the model and improve the efficiency of the optimization model. Simulation analysis based on IEEE 30-bus system verifies the superiority of the model and algorithm.
