地点：长安校区理学院383会议室

主题：Powergrid questions for oscillator networks: Stochastic spreading in networked systems and nonlinear stability.

内容简介：Powergrids are continental sized machines of coupled oscillators. While they traditionally consisted of relatively few machines that fed a distribution network, the ongoing energy transition and the shift to distributed renewable generation will see the system change to one in which a large number of oscillators interact dynamically. The task to keep the system stable thus raises important questions for the study of network dynamics.

In this talk I will review recent results on the linear and non-linear network behavior of inertial oscillators. Such oscillators provide an interesting model for the dynamics of current and future power grids and their control. In both cases we see that the presence of many subtle dynamical effects in the behavior of the oscillators and the lines, such as energy losses in the network and small delays in the control action, can have large emergent effects on the characteristics of the entire network.
