Stability of interacting grid-connected power converters [PDF]
Journal of Modern Power Systems and Clean Energy, 2013 The power grid in a typical micro distribution system is non-ideal, presenting itself as a voltage source with significant impedance. Thus, grid-connected converters interact with each other via the non-ideal grid. In this study, we consider the practical scenario of voltage-source converters connected to a three-phase voltage source with significant ...
