Design and Optimization of Dynamic Voltage Restorers for Enhancing Power Quality and Fault Ride through (FRT) in Grid-Integrated Hybrid Energy Systems

SMART MOVES JOURNAL IJOSCIENCE
The integration of renewable energy sources, such as solar and wind, into modern power grids presents challenges in maintaining power quality and stability, particularly under fault conditions like voltage sags and swells. This research focuses on the design and optimization of Dynamic Voltage Restorers (DVRs) to enhance power quality and Fault Ride ...

Short‐Circuit Current Analysis of Grid‐Connected Inverters: An Analytical Approach Using Hardware Natural Response and Control Superposition

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a closed‐form analytical framework predicting the sub‐cycle transient peak currents of grid‐following and grid‐forming inverters during short‐circuit faults. The method uniquely decouples the fault current into a hardware natural response and a control‐commanded response, enabling rapid estimation of instantaneous initial peaks ...

Receiving-end AC fault ride-through method of hybrid HVDC transmission based on adaptive DC voltage reduction

International Journal of Electrical Power & Energy Systems
The hybrid high-voltage direct current (HVdc) transmission that combines line-commutated converters (LCCs) at the sending end and modular multilevel converters (MMCs) at the receiving end is a promising choice for integrating bulk renewable power ...

Addressing Distance Relay Mal‐Operation in Low‐Inertia Grids: A PLL‐Informed Power Swing Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A key advantage of the proposed approach is its independence from PLL control settings, relying solely on locally measured electrical quantities, which ensures robust, fast, and practical implementation in existing commercial distance relays. ABSTRACT The increasing penetration of inverter‐based resources (IBRs) has substantially reduced system inertia

Data Centre Model for Transient Stability Analysis of Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a dynamic load model for Data Centers (DCs) to accurately simulate their impact on power system transient stability. The model uniquely incorporates key DC components, including Uninterrupted Power Supplies (UPS), cooling systems modeled as induction motors, and specific load patterns for Artificial Intelligence (AI) and batched ...

Research on the Automatically Independent Controlling Algorithm of the Grid-Connected PV Inverter Jointly Considering Dynamic Load Features and Active LVRT Capability

IEEE Access, 2023
Due to environmental and energy policies in recent years, some countries will install many PV generations into power systems in the future. Under this condition, it is worrisome that the disconnection of the PV occurs because of a voltage drop triggered ...

Reliability Improvement of GFM Inverters: Diagnosing DC‐Side Instability Mechanisms and Overvoltage Faults Induced by PV and ESS

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper investigates GFM inverter reliability by analysing DC‐side dynamics from PV and ESS, which can cause DC‐link overvoltage and instability. We demonstrate that high PV generation is a key threat, while counter‐intuitively, limiting ESS capacity can enhance stability by damping control‐induced oscillations.

Transient characteristics and adaptive fault ride through control strategy of DFIGs considering voltage phase angle jump

Journal of Modern Power Systems and Clean Energy, 2017
Wind power in China has experienced fast development in recent years. However, areas rich in wind power resources are often far away from loads centers, which leads to weak connection between wind turbines and power grid.

Strengthening Renewable‐Rich Weak Grids Through Improved Voltage Stability and Fault‐Ride Through Capability

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
To enhance grid stability and resilience in high renewable energy scenarios, this research proposes a cascaded control optimization framework guided by a novel dynamic resilience metric. Validated on a representative Australian grid, the framework significantly reduced voltage overshoot and extended fault clearing times, offering a robust solution for ...
