TL;DR: This paper presents a comprehensive virtual generator control method for the full converter wind turbine, with a minute-level energy storage in the dc link as the energy buffer, which allows it to work under both grid-connected and stand-alone condition.

TL;DR: The component connection method (CCM) in the frequency domain for stability analysis in the synchronous d–q frame is introduced, by proposing a method of deriving the impedance matrix of the connection networks of inverter-based ac power systems.

TL;DR: In this paper, a synchronous generator emulator was developed by using a three-phase voltage source converter for transmission level power system testing, and the voltage type ideal transformer model was selected considering accuracy and stability.

TL;DR: In this paper, a hardware testbed platform emulating multiple-area power system scenario dynamics has been established aiming at multiple time-scale real-time emulations, where a constant-impedance, constant-current, and constant-power (ZIP) model has been used for static load types, while a three-phase induction motor model was built to represent dynamic load types.

TL;DR: In this article, the authors proposed two sequence-impedance-based harmonic stability analysis methods for three-phase inverter-based multibus ac power systems, based on the summary of all major connection types including mesh, the proposed Method 1 can analyze the harmonic stability of multi-bus ac systems by adding the components one by one from nodes in the lowest level to areas in the highest system level.
