Low-inertia control of a large-scale renewable energy penetration in power grids: A systematic review with taxonomy and bibliometric analysis

Energy Strategy Reviews
The crux to meet the daily exponential growth in power demand and reduce the carbon footprint has seen to rejuvenate the consideration of large-scale renewable energy penetration (LsREP) in the power grid.

Power system inertia estimation method based on maximum frequency deviation

IET Renewable Power Generation, 2022
In order to solve the problem that the inertia estimation method based on the rate of change of frequency (RoCoF) is only applicable to the centre of inertia (COI) frequency, a novel inertia estimation method is proposed based on the maximum frequency ...

The case for redefinition of frequency and ROCOF to account for AC power system phase steps

, 2017
All conventional techniques for measuring frequency result in large deviations to the perceived or calculated frequency when the AC waveform undergoes a phase step.

Experimental and HIL investigation of under-frequency and rate of change of frequency load shedding schemes in interconnected networks with high penetration of renewable generation

, 2021
Under-frequency Load Shedding Schemes (UFLS) are a well-established part of any under-frequency defence plan. Their future effectiveness in systems with increased penetration of renewable energy sources without rotating mass should however be questioned:

Demonstration of Frequency Regulation via Autonomous Load Control

IEEE Access
With the increasing proliferation of photovoltaic (PV) and wind power globally, frequency regulation by balancing generation and load in power systems is becoming increasingly difficult owing to reductions in dispatchable power and inertia.

The Impact of PLL Dynamics on the Low Inertia Power Grid: A Case Study of Bonaire Island Power System

Energies, 2019
To prepare for the future high penetration level of renewable energy sources, the power grid’s technical boundaries/constraints for the correct operation of powerelectronics interfaced devices need to be further examined and defined.

A Novel Digital Twin Platform for Accelerating Power Systems Restoration

Energy Internet, EarlyView.
Hardware Architecture Design of DT System in Laboratory. ABSTRACT With the global energy structure transforming towards the goal of net zero emissions, the penetration of an inverter‐based resource (IBR) in power systems is increasing. This transformation poses two critical challenges: the system post blackout restoration process becomes extremely ...

Fast Coordinated Power Control for Improving Inertial and Voltage Support Capability of Battery Energy Storage Systems

CSEE Journal of Power and Energy Systems
This paper proposes a fast coordinated power control method based on two augmented channels (AC) in battery energy storage system (BESS) to improve inertial and voltage support capability, i.e., a frequency-reactive power channel (FRPC) and a voltage ...
