Revealing drivers and risks for power grid frequency stability with explainable AI. [PDF]
Patterns (N Y), 2021 Summary Stable operation of an electric power system requires strict operational limits for the grid frequency. Fluctuations and external impacts can cause large frequency deviations and increased control efforts. Although these complex interdependencies

Frequency Stability-Constrained Unit Commitment: Tight Approximation Using Bernstein Polynomials [PDF]
IEEE Transactions on Power Systems, 2022 As we replace conventional synchronous generators with renewable energy, the frequency security of power systems is at higher risk. This calls for a more careful consideration of unit commitment (UC) and primary frequency response (PFR) reserves.

Electronics, 2023 The high penetration of inverter-fed renewable energy sources (RESs) in modern energy systems has led to a reduction in the system’s inertial response. This reduction in the rotational inertial response is associated with synchronous generation and might

Frequency Stability of Synchronous Machines and Grid-Forming Power Converters [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 An inevitable consequence of the global power system transition toward nearly 100% renewable-based generation is the loss of conventional bulk generation by synchronous machines (SMs), their inertia, and accompanying frequency- and voltage-control ...

Frequency stability of a wavelength meter and applications to laser frequency stabilization [PDF]
Applied Optics, 2015 Interferometric wavelength meters have attained frequency resolutions down to the MHz range. In particular, Fizeau interferometers, which have no moving parts, are becoming a popular tool for laser characterization and stabilization. In this article, we characterize such a wavelength meter using an ultra-stable laser in terms of relative frequency ...

Improvement of Power System Frequency Stability With Universal Grid-Forming Battery Energy Storages
IEEE Access, 2023 Large-scale integration of inverter-based renewable generation leads to the reduction of power systems’ natural inertia. Therefore, the dynamics of the future power systems will be more sensitive than in the traditional systems with high-inertia rotating

Security-Constrained Unit Commitment Considering Locational Frequency Stability in Low-Inertia Power Grids [PDF]
IEEE Transactions on Power Systems, 2021 With increasing installation of wind and solar generation, conventional synchronous generators in power systems are gradually displaced resulting in a significant reduction in system inertia.
