Abstract

The low-frequency oscillations (LFOs) inherent inpower systems will be impacted by the increasing penetrationof renewable energy sources (RESs). This paper investigates theimpact of virtual synchronous machine (VSM) based RESs on theLFOs in power systems. A detailed two-machine test-bed has beendeve...
