Stability is a fundamental premise for secure operation of every electric power system. As the loading demands are constantly increasing and the transmission networks are aging, the operating conditions of worldwide power systems have been pushed ever closer to their stability limits. Meanwhile, the integration of renewable energy sources has been constantly increasing. Particularly, Canada is a world leader in the production and use of all kinds of renewable energy. Although renewables bring numerous benefits, they also pose new challenges to power system stability. For example, the distinct dynamic responses of wind turbines and photovoltaic generators to disturbances may aggravate the contingencies, and thus deteriorate the stability of the overall power grid. As the penetration of renewables continues to increase in the foreseeable future, it is imperative to study the impacts of different renewables on various power system stability properties in order to enhance the stability and reliability of modern low carbon power systems.

稳定是电力系统安全运行的基本前提。随着负荷需求的不断增加和输电网络的老化，世界范围内电力系统的运行条件越来越接近其稳定极限。与此同时，可再生能源的集成度也在不断提高。特别是，加拿大在各种可再生能源的生产和使用方面处于世界领先地位。尽管可再生能源带来了许多好处，但它们也给电力系统的稳定性带来了新的挑战。例如，风力涡轮机和光伏发电机对扰动的不同动态响应可能会加剧突发事件，从而恶化整个电网的稳定性。在可预见的未来，随着可再生能源普及率的不断提高，为了提高现代低碳电力系统的稳定性和可靠性，研究不同可再生能源对电力系统各种稳定特性的影响势在必行。
