摘要(Abstract):
随着新能源接入比例的持续攀升和负荷峰谷差的日益增大,电力系统的调峰形式越来越严峻,尤其是在供需平衡较为紧张的紧急时段,系统调峰对于发电侧调节灵活性的需求非常迫切。目前,发电侧的调节主要依靠少数几类发电资源,而核电、外来电等其他发电资源的灵活性尚未得到有效挖掘和利用。为了协调多元发电资源的灵活调节能力,缓解系统在紧急时段的调峰压力,构建了考虑多元发电资源灵活性的电力系统紧急调峰调度框架,提出了基于日前机组组合的紧急时段评估方法,并在此基础上建立了考虑多元发电资源调节特性的电力系统调峰调度优化模型。算例仿真结果验证了所提框架和方法的有效性。
With the increasing access proportion of renewable energies and the enlarged difference between peak and valley loads, the peak regulation modes of power systems are suffering more and more severe situation. Especially in the emergency period when the supply and demand balance is tight, the requirement for the regulation flexibility in the generation side is very urgent to conduct peak shaving of the system. At present, the regulation capability in the generation side is mainly provided by a few types of power generation resources, while the flexibilities of other types of generation resources in the system, e.g., nuclear power and external power, have not been effectively exploited and utilized. This paper aims to coordinate the flexible adjustment ability of multiple power generation resources and relieve the peak shaving pressure of the power system in the emergency period. Firstly, the framework of emergency peak shaving scheduling of the power system considering the flexibilities of multiple power generation resources is constructed. Then, an emergency period evaluation method based on day-ahead unit commitment is proposed. On this basis, an optimal dispatch model of peak shaving for the power system considering the regulation characteristics of multiple power generation resources is established. Finally, simulation results verify the effectiveness of the proposed framework and method.
