As renewable resources gradually replace conventional generation based synchronous machines, the dynamics of the modern grid changes significantly and the system synchronous inertia decreases substantially. This transformation poses severe challenges for power system stability; for instance, it may lead to larger initial rate of change of frequency and increase frequency excursions. However, new opportunities also arise as novel converter control techniques, so-called grid-forming strategies…

Optimal Placement of Virtual Inertia in Power Grids
This paper considers a linear network-reduced power system model along with an $\mathscr {H}_2$ performance metric accounting for the network coherency and provides a set of closed-form global optimality results for particular problem instances as a computational approach resulting in locally optimal solutions.

A novel synchronized phasor measurement units (PMUs)-based dynamic system inertia estimation method is proposed, derived using electrical distance and clustering algorithm, which considers the impact of location of measurements relative to infeed load and impact of oscillations.
Minimum Synchronous Inertia Requirement of Renewable Power Systems
The installed capacity of wind generation and photovoltaics (PV) in many countries is going to dominate generation fleets in a bid to meet growing renewable energy targets. Synchronous inertia has
Effect of inertia heterogeneity on frequency dynamics of low‐inertia power systems
The resulting changes in the system's dynamic behaviour due to frequency and voltage interactions can increase the actual active power imbalance size following a credible contingency so that careful considerations to protect the system against an excessively high rate of change of frequency should be made.
Stochastic Unit Commitment in Low-Inertia Grids
A computationally efficient approach is proposed that allows to recast the nadir constraint by introducing appropriate bounds on relevant decision variables of the UC model to preserve the mixed-integer linear formulation of the stochastic UC model.
Demand Side Contributions for System Inertia in the GB Power System
As the penetration of intermittent, low carbon generation increases, system inertia will decrease dramatically and pose a major threat to system stability. The majority of research in this area
Inertia location and slow network modes determine disturbance propagation in large-scale power grids
This model of the high voltage synchronous grid of continental Europe shows that, beyond absorbing frequency disturbances following nearby faults, inertia also mitigates frequency disturbances from distant power losses, provided both the fault and the inertia are located on the support of the slowest modes of the grid Laplacian.
