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

Evaluation of Virtual Synchronous Machines With Dynamic or Quasi-Stationary Machine Models [PDF]
IEEE Transactions on Industrial Electronics, 2017 This paper presents a comparison of the small-signal stability properties for Virtual Synchronous Machines (VSMs) with dynamic and quasi-stationary representation of the internal Synchronous Machine (SM) model. It is shown that the dynamic electrical equations may introduce poorly damped oscillations when realistic stator impedance values for high ...
