Research progress on probabilistic small signal stability of power system
:With the development of new energy permeability,it applies frequently in electric power system.However, considering the characteristics of new energy sources with strong randomness and large volatility,it will affect the small signal stabilityand restrict the development ofhigh-energy new energy power systems.This thesisfocuses on the source of small signalstability, the impact of the power system and the analysis methods. Firstly, the article briefly introduces the concepts of small signalstability,explains the influence from wind power and other uncertain new energy power generation, electric vehicles, new loads and network security on power systems.Classifies the small signal analysisstability methods and analyzes the Monte Carlo Method (MCM), Stochastic Response Surface Method (SRSM) and the Probability Collocation Method (PCM) principles and status. Finally, the article introducesthe suppression measures of small signal stability at current stageand proposes some future development advises of power system.
