Special Issue on Nonlinear Dynamics in Power Electronics-Enabled Energy Systems

Power electronics converters are indispensable parts of modern energy systems for achieving the required flexible energy conversion and transmission functions. The use of power electronics enables energy systems to fulfill critical roles in various utility applications, but at the same time necessitates imposition of stringent requirements for stability and safety purposes. Conventional linearized analysis methods usually assume that the system under study operates at a fixed point with a small range of variation. However, the dynamical behavior of power electronics systems often invalidates the small-signal assumption due to the nonlinear characteristics of power electronics devices and operations, especially when the system exhibits inevitable disturbances such as the source/load power fluctuations, device/transmission line faults, etc. This Special Issue comprises 18 papers presenting recent research trends and cutting-edge research results in the field of nonlinear dynamics in power electronics-enabled energy systems.
