Enhanced control and parameter analysis for virtual synchronous generators without PLL

The Journal of Engineering, 2019
Currently, virtual synchronous generator (VSG) technology is proposed to be a solution to stability controlling of micro-source inverter. However, the deviation from phase locked loop (PLL) influences the reference frequency calculating which is ...

Frequency safety demand and coordinated control strategy for power system with wind power and energy storage

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
The highlights of the article are summarized as follows. The virtual inertia and primary frequency regulation control of wind power and energy storage should reasonably utilize the system's energy reserve while taking into the three safety requirements. The frequency response extreme time is calculated to estimate the virtual inertia of the system, and

A Novel Sliding Mode Control Strategy for VSG‐Based Inverters with Disturbance Estimation

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
To enhance the robustness of the VSG‐based inverter control system against uncertain disturbances, this paper proposes a novel sliding mode control strategy consisting of two control layers for VSG‐based inverters based on disturbance estimation. ABSTRACT The interface inverter control system based on virtual synchronous generator (VSG) technology, has

Frequency Dynamical Behaviour and Frequency Equilibrium Point of Multi‐VSC Systems

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper investigates the frequency dynamical behaviour of new‐generation power systems with 100% renewable energy. The bipartite behaviour for a purely grid‐following (GFL)‐voltage source converter (VSC) system and a hybrid GFL‐VSC and GFM‐VSC system with at least one GFM‐VSC is uncovered.
