Virtual Inertia Control and Small-Signal Stability Analysis of Electric Vehicle [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2023 In electric vehicles (EVs), the small size of the dc link capacitor results in significant voltage deviations when there are changes in load or uncertain fluctuations from the power resources. This causes a decline in voltage quality.

Sustainable Energy, Grids and Networks, 2021 Abstract The behavior of constant power loads is known to be a potential cause of instability in DC microgrids. This issue is addressed by the DC microgrid stabilizer proposed in this paper. It relies on active stabilization through power electronic control by introducing a virtual positive resistance to counteract the negative incremental resistance
