Journal of Modern Power Systems and Clean Energy, 2021 This study focuses on a virtual synchronous machine (VSM) based on voltage source converters to mimic the behavior of synchronous machines (SMs) and improve the damping ratio of the power system. The VSM model is simplified according to some assumptions (

Internal Induced Voltage Modification for Current Limitation in Virtual Synchronous Machine
Energies, 2022 Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of
