The three-phase voltage source converter (VSC) suffers from complex dynamics due to large signal disturbances such as grid voltage dips. In this paper, the instability phenomena of current loop and voltage loop are identified in three-phase grid-connected VSCs. Moreover, the interaction of the voltage loop and current loop is analyzed. Thus, the fault current under such situation can be calculated...
The photovoltaic-battery hybrid power system is a kind of flexible renewable power generation system, which is composed of a photovoltaic array and a battery connected to an output DC bus via power converters. The system can work with multiple structures and multiple operating modes due to the source and load states. Particularly, the nonlinear nature of the constant power load will destablize the...
Three-phase voltage source converters (VSC) are commonly used to convert ac power from a three-phase grid to a regulated dc voltage with unity input power factor. The control of the VSC is normally achieved by an outer voltage feedback loop and a sinusoidal pulse-width-modulated (SPWM) inner current loop. However, the non-ideal power grid and the presence of other interacting loads give rise to nonlinear...
