This article presents a small-signal study, based on sensitivity analysis, of voltage source converter (VSC) operating as grid-following device. type operation is standard for integrating distributed energy resources directly into primary grid without considering the control over specific variables (e.g., and frequency), thus maximizing amount injected active power. The present study adopted cl...

The virtual synchronous generator (VSG) technique is used to simulate the external characteristics of a (SG) provide certain damping and inertia power systems. However, it may easily cause low-frequency oscillation system. We studied small-signal stability grid-connected generator. Firstly, models single-VSG multi-VSG systems were established. Subsequently, system eigenvalues obtained by solvin...

The microgrid (MG) system is a controlled and supervised power consisting of renewable energy (RE)-based distributed generation (DG) units, loads, storage. MG can be operated autonomously or while connected to the grid. Higher intermittencies uncertainties observed in MGs compared conventional system, which possible source small-signal stability systems. It seen as disturbances around stable op...

This paper focuses on the small-signal stability of power system integrated with DFIG-based wind farm. The model of DFIG for small-signal stability analysis has built; the 3-generator 9-bus WECC test system is modified to investigate the impacts of large scale integration of wind power on power system small-signal stability. Different oscillatory modes are obtained with their eigenvalue, freque...
