【摘要】：针对实时发电计划应用模块上线后,如何与自动发电控制衔接以进一步提高调度运行精益化水平的问题,提出实时发电计划中的机组控制模式及其转换机制,建立了实时发电计划与自动发电闭环控制优化模型。模型根据控制模式的不同将机组分为自动发电控制机组、缓冲机组和计划机组3类,分别对不同控制模式的机组进行建模,可实现自动发电控制机组与缓冲机组控制模式的动态转换,同时将系统可调容量在不同类型机组间进行动态转移,达到可调容量合理分布的效果。采用IEEE 118节点系统对所提模型进行测试,结果验证了所提模型的可行性与有效性,表明实时发电计划编制时,通过兼顾自动发电控制需求,可以合理地在机组间分配系统可调容量资源,降低自动发电控制的运行压力,实现对控制资源的有效利用。
[Abstract]:Aiming at the problem of how to link up with automatic generation control after the application module of real-time generation plan is on-line to further improve the lean level of dispatching operation, this paper puts forward the unit control mode and its conversion mechanism in real-time generation plan. The optimization model of real-time generation planning and closed-loop control of automatic generation is established. According to the different control modes, the units are divided into three types: automatic generator control unit, buffer unit and planning unit, and the units with different control modes are modeled respectively. The dynamic conversion of control mode between automatic generator set and buffer unit can be realized. At the same time, the adjustable capacity of the system can be dynamically transferred between different types of units to achieve the effect of reasonable distribution of adjustable capacity. The IEEE 118 node system is used to test the proposed model. The results verify the feasibility and effectiveness of the proposed model. It is shown that the real-time power generation planning takes into account the need of automatic generation control by taking into account the requirements of automatic generation control. The adjustable capacity resources of the system can be reasonably distributed among the units, the operating pressure of automatic generation control can be reduced, and the effective utilization of the control resources can be realized.
