摘　　要：随机性广泛存在于自然、工程和社会系统中,电力系统也不例外。20世纪70年代左右,电力系统研究逐渐考虑随机性,但偏重于稳态随机问题,而动态问题研究仍然是确定性的。近年来,新能源发电与电动汽车等的广泛接入,给电力系统动态带来不可忽视的随机性。为此,文中提出电力系统随机动力学的研究框架,聚焦电力系统在随机因素作用下的动态问题,包括电力系统的随机动力学模型、随机动态响应、随机稳定性、随机安全性、随机优化控制,并给出研究建议。Randomness exists extensively in nature, engineering and social systems, the power system not excepted. Randomness has gradually taken into consideration in power system analysis since the 1970s, with emphasis on analysis of steady-state random problems while research on power system dynamics is still based on the deterministic theory. In recent years, with increasing integration of typical sets of stochastic sources into power systems, such as the large-scale renewable power generation and electric vehicles, the influence of randomness on power system dynamics can no longer be neglected. For this reason, a research framework is proposed for stochastic dynamics of power system focusing on dynamic problems under the action of randomness, including stochastic dynamic modelling, stochastic dynamic responses, stochastic stability, stochastic dynamic security and stochastic optimum control of power system. Some suggestions are given for the research.
