为了应对大规模新能源并网下电力系统的多种随机因素,提出了一种基于“鲁棒调度计划”+“鲁棒运行区域”的多时间尺度滚动调度模式。首先,在分析传统多时间尺度调度模式存在问题的基础上,提出了一种改进的多时间尺度鲁棒调度模式。然后,阐述了鲁棒调度的基本实施过程,通过算例对实施过程进行模拟,并与传统调度模式进行对比说明了所提模式的优越性。最后,对实现多时间尺度鲁棒调度模式的关键技术进行探讨,为面向新能源并网的电力系统调度提供参考思路。
To cope with the multiple stochastic factors of power system with large-scale renewable energy, a multi-time scale dispatching mode is proposed. The proposed mode is based on the rolling optimization of "robust dispatching plan" + "robust operational region". First, the problems of traditional dispatching mode are analyzed. Based on these problems, an improved mode of robust dispatching is put forward. Then, the implementation process of robust dispatching is detailed and an example is studied to demonstrate the process. The advantages of the proposed mode are verified by comparing with the traditional dispatching mode. Finally, the key technologies to realize the proposed robust dispatching mode are discussed, which can provide the reference for the dispatching of power system connected with large-scale renewable energy.
