配电网多端直流互联系统中分布式光伏与电动汽车充电桩的大量接入,导致系统呈现高度电力电子化和强不确定特征,给系统稳定运行带来了严峻挑战。为了分析源荷不确定性对多端直流互联系统稳定性的影响,文中提出了计及源荷不确定性的概率化阻抗建模方法,通过基于矩信息的启动函数拟合实现系统稳定概率的分析,进而分析了电网参数与电力电子设备控制参数对系统稳定性概率特征的影响规律。最后,通过MATLAB/Simulink仿真
与蒙特卡洛法对比验证了所提方法的有效性。
A large number of distributed photovoltaic and electric vehicle charging piles access in the multi-terminal DC interconnected system of the distribution network. This results in a high power-electronization and strong uncertainty of the system
which brings serious challenges to the stable operation of the system. To analyze the impact of source-load uncertainty on the stability of the multi-terminal DC interconnected system
this paper proposes a probabilistic impedance modeling method considering the source-load uncertainty. The analysis of the system stability probability is achieved through the starting function fitting based on the moment information. Then the influence of the grid parameters and the control parameters of the power electronic equipment on the probability characteristics of the system stability is analyzed. Finally
the effectiveness of the proposed method is verified by MATLAB/Simulink simulation compared with Monte Carlo method.
