Frequency regulation in adaptive virtual inertia and power reserve control with high PV penetration by probabilistic forecasting

Frontiers in Energy Research, 2022
The large-scale deployment of sustainable energy sources has become a mandatory goal to reduce pollution from electricity production. As photovoltaic (PV) plants replace conventional synchronous generators (SGs), their significant inherent rotational ...

Virtual Moment of Inertia of Marine Propellers

Journal of Zosen Kiokai, 1966
In order to culculate the critical speed of propeller shaft, the accurate value of virtual moment of inertia of marine propeller should be estimated.Virtual moment of inertia consists of the mass moment of inertia of propeller I and the additional moment of inertia by entrained water Δ I.It is usual to estimate Δ I by making a percentage additon to I ...

Establishment of an auxiliary virtual damping loop for the superior inertial response in the microgrid

IET Smart Grid, 2019
Low inertial microgrids in the power network are extremely sensitive toward any uncertainties. Therefore, the practise of complementing inertia virtually in microgrids has earned huge attention in recent time.
