Sub synchronous oscillations
WebUnder weak grid, the grid-connected inverter can easily cause sub/super-synchronous oscillations, which are determined by the oscillation modes of sys… Web11 Apr 2024 · The sub/super-synchronous oscillations are mainly caused by the nonlinear loads, switch-mode inverters, and so on connected to the power grid and result in reduced damping or even negative damping. For example, a sustained oscillation, where its frequency is about 20 Hz, is first observed in Texas's southern power grid [ 3 ].
