Adaptive Virtual Inertia Provision for AC and MT HVDC Grids Based on Converters' Capabilities

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
The paper presents two adaptive methodologies for integrating PECs into AC and MT‐HVDC grids, aimed at fully utilising the operational capacity of the PECs in response to variations in AC frequency and DC voltage. The proposed approach dynamically adjusts maximum allowable virtual inertia based on the system's equilibrium point, allowing for a more ...

Distributionally robust optimization of voltage fluctuations and imbalance in islanded bipolar DC microgrids

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Here, we investigate voltage fluctuations and unbalancing of a droop‐controlled islanded bipolar DC microgrid caused by variations of generated or consumed power of DC microgrid. A new energy management system is proposed, considering voltage stability constraints alongside the economic, technical, and environmental aspects of DC microgrid operation ...

Implementing Enhanced Fault Detection and Classification in DC Microgrids With Savitzky‐Golay Filter

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
This paper introduces a methodology for fault detection and classification in DC microgrids. It transforms the measured current from only one end of the protected line into a novel modal current. Then, it employs the second‐order derivative of the Savitzky‐Golay filter to introduce a novel fault detection index for discriminating the faults in a wide ...

A Novel Meta‐Learning‐Based Reinforcement Controller for Voltage Regulation of an Interleaved Boost Converter in Solar Photovoltaic Systems

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
This paper introduces an adaptive meta‐learning‐based DDPG (AM‐DDPG) controller for voltage regulation in solar PV systems using a three‐leg interleaved boost converter. Unlike conventional DDPG controllers, the proposed controller dynamically tunes its hyperparameters, enhancing adaptability under varying irradiance and temperature. Simulation results

Deep learning‐based barrier‐function super‐twisting sliding mode control for integrating renewables in smart grid

IET Smart Grid, Volume 8, Issue 1, January/December 2025.
An enhanced deep neural network optimised with a combination of particle swarm optimisation and genetic algorithm is proposed. A barrier‐function‐based adaptive super‐twisting sliding mode controller is devised for tracking maximum peak power and bus voltage. Controller hardware‐in‐the‐loop‐based real‐time simulations are conducted. Abstract This study

Robust PSO‐Optimized Power Control for Stand‐Alone Variable‐Speed DFIG Wind‐Based High Stability and Power Quality Enhancement: Hardware Investigation‐Based dSPACE1103

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Wind energy conversion systems (WECSs) operating in stand‐alone mode are increasingly recognized as a promising solution for delivering reliable renewable electricity in remote areas. However, their performance is often hindered by sudden wind speed fluctuations and parameter variations, which can compromise both stability and power quality. To address
