Impact of inertia constant on frequency dynamics of a power system
Ceylon Journal of Science, 2021 Renewable Energy Sources (RES) are emerging as a mainstream electricity generation option in many parts of the world. However, achieving the frequency stability is a major challenge when the RES penetration is high.

Energy Reports, 2023 The rate of change of frequency (ROCOF) has become a key parameter to be monitored under high penetration of renewable energy. Any significant ROCOF should be mitigated immediately to avoid any shutdown of power plants and hence power interruptions to ...

Effective Inertial Response With New Coordinated Control for Multiple WPPs
IEEE Access, 2022 This paper proposes a new coordinated control for multiple wind power plants (WPPs) based on two stepwise inertial control (SIC) methods to effectively release the kinetic energy of the permanent magnet synchronous generators (PMSGs) and improve their ...

Gauging frequency and detection of rating changes [PDF]
Hydrological Sciences Journal, 1987 For gauging stations where rating changes are frequent, errors in streamflow estimation can occur from using out-of-date stage-discharge ratings. The chance of such errors occurring can be reduced by increasing the frequency of flow gaugings. An expression for the confidence in the accuracy of a flow record is derived which depends on the time interval

Influence of Continuous Provision of Synthetic Inertia on the Mechanical Loads of a Wind Turbine
Energies, 2021 In many electrical grids, the share of renewable energy generation increases. As these generators are typically connected to the grid via inverters, the level of grid inertia decreases.

Local Frequency-Based Estimation of the Rate of Change of Frequency of the Center of Inertia [PDF]
IEEE Transactions on Power Systems, 2020 This letter proposes a novel technique for estimating the rate of change of frequency (RoCoF) of the center of inertia (CoI) in power systems. To offer a holistic picture of the system's frequency response, the proposed technique requires local frequency at the point of measurement, only.

OpenEdgePMU: An Open PMU Architecture with Edge Processing for Future Resilient Smart Grids
Energies, 2023 The increase in renewable energy sources (RESs) in distribution grids is a major driver for achieving green energy goals worldwide. However, RES power inverters affect power quality, increase power losses, and, in certain cases, may cause power ...

Review of RoCoF Estimation Techniques for Low-Inertia Power Systems
Energies, 2023 As the traditional generation is gradually replaced by inverter-based resources, a lack of rotational inertia is now a common issue of modern power systems, which leads to an increasingly larger rate of change of frequency (RoCoF) following contingencies
