Impedance modelling and grid integration stability evaluation of three‐phase virtual synchronous generator

IET Power Electronics, 2022
Virtual synchronous generator (VSG), which can behave with analogous characteristics as the conventional synchronous generator (SG) and provide voltage and inertia/damping support, is universally regarded as a grid‐friendly interface.

Virtual Synchronization Control Strategy for UHVDC with Secondary Frequency Modulation Based on PI Control

Zhongguo dianli, 2022
Under traditional control strategy, UHVDC transmission system lacks inertia and damping characteristics, so it can't effectively adjust the frequency of AC system dynamically.

Multi-objective optimization of HESS control for optimal frequency regulation in a power system with RE penetration

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Concerns over fossil fuel emissions and their hazardous effects have led to a shift away from conventional power plants and focus more on the expansion of renewable energy sources. This shift has resulted in reduced inertia and resulted in poor frequency

Lyapunov‐Function‐Based Stability Region Estimation in Transient Stability Assessment of Inverter‐Based Resources: A Review

High Voltage, EarlyView.
ABSTRACT Electric power systems are undergoing a fundamental transition from synchronous generator (SG)‐dominated systems to inverter‐based resource (IBR)‐dominated systems. Lyapunov‐ and energy‐function‐based direct methods provide an effective way to estimate the stability region, also known as the region of attraction (ROA), and have become a ...

Analysis of Out‐of‐Step Oscillation Centre Migration Under Increasing Renewable Energy Penetration in Large‐Scale Power Systems

IET Smart Energy Systems, Volume 2, Issue 3, Page 181-190, September 2026.
Increasing renewable penetration causes out‐of‐step oscillation centres to migrate away from renewable integration points. Two distinct migration modes—continuous drift and large‐range jumps with instability‐mode changes—are identified, providing guidance for adaptive splitting protection in future power systems.
