Effective Control of Smart Hybrid Power Systems: Cooperation of Robust LFC and Virtual Inertia Control Systems
A modern power system is expected to consist primarily of renewables
which either lack or have less rotating masses (i.e.
source of inertia) compared to the traditional generation sources. However
the growth of renewables generation
based on power electronics
can substantially decrease the inertia levels of renewable power grids
which can create several frequency stability issues
resulting in power system degradation. To address this issue
this paper presents a recent virtual inertia scheme predicated on electric vehicles (EVs) to mimic the necessary inertia power in low-inertia smart hybrid power systems (SHPSs)
thus regulating the system frequency and avoiding system instability. Moreover
to guarantee robust performance and more stability for SHPSs against multiple perturbations
system uncertainties
and physical constraints
this paper also proposes a robust control strategy relying on a coefficient diagram method (CDM) for the load frequency control (LFC) of SHPSs considering high renewables penetration and EVs. The efficacy of the proposed system (i.e.
robust LFC with the proposed VIC strategy) is validated by comparison with a conventional LFC with/without the proposed VIC system. In addition
the simulation outcomes show that the proposed system can considerably support smart low-inertia hybrid power systems for many different contingencies.
