基于随机矩阵理论的电力系统暂态稳定性分析
Power System Transient Stability Analysis Based on Random Matrix Theory
摘要
Abstract
ABSTRACT:Power system transient analysis is an important means to ensure the stable operation of power network. With the development of the Wide-Area Management (WAMS), a large amount of operational data with spatiotemporal characteristics are produced. Traditional power system transient analysis is based on the physical model, in which different dimensions data are incorporated into strict mathematical formulas, unable to take full advantage of massive power grid data. Data-driven models were presented for power system transient stability analysis based on random matrix theory, taking into account the characteristics of the grid operation data. The status of power grid operation data application was summarized. Then the mean spectral radius calculation method was given and the impacts of different disturbances on the power system were analyzed. A quantitative evaluation index was proposed to assess the impact degree of disturbance by combining random matrix theory with time series analysis method. Finally, IEEE 39 nodes system was used to verify the feasibility and correctness of the method proposed.关键词
