摘要
风电等新能源的大规模并网严重影响了电力系统的暂态稳定性。针对新能源电力系统暂态稳定问题,提出基于暂态能量辨识的含规模化储能的新能源电力系统暂态稳定控制方法。首先,构建新能源电力系统的线路稳定裕度和系统暂态稳定裕度指标,准确辨识系统暂态稳定性;然后,提出附加线路暂态能量控制的改进储能控制策略,更好提升系统暂态稳定性;最后,在New England10机39节点系统中进行仿真验证。算例分析表明,所提方法能准确辨识系统暂态稳定分布情况,有效改善新能源电力系统暂态稳定性。
The large-scale grid connection of new energy sources such as wind power has seriously affected the transient stability of power systems.Aiming at the problem of transient stability of new energy power systems,a transient stability control method based on transient energy identification for new energy power system with scaled energy storage is proposed.Firstly,the line stability margin and system transient stability margin indexes of the new energy power system are constructed to accurately identify the system transient stability.Then,the improved energy storage control strategy with additional line transient energy control is proposed to better enhance the transient stability of the system.Finally,simulation verification is carried out in the New England system with 39 nodes and 10 machines.Case analysis shows that the proposed method can accurately identify the distribution of system transient stability and effectively improve the transient stability of new energy power systems.
