Review of the Configuration and Transient Stability of Large-Scale Renewable Energy Generation Through Hybrid DC Transmission

open access: yesCES Transactions on Electrical Machines and Systems
Based on the complementary advantages of Line Commutated Converter (LCC) and Modular Multilevel Converter (MMC) in power grid applications, there are two types of hybrid DC system topologies: one is the parallel connection of LCC converter stations and ...

Development of the Human–Equine Attachment Scale

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Human–horse relationships encompass diverse roles, from companion to competition partner. The impact of such bonds informs owner decision‐making regarding horse management and veterinary care, yet standardised instruments to measure these unique bonds are limited.

A comprehensive FRT strategy based on individual arm capacitor voltage control for MMC in hybrid AC/DC distribution grids

open access: yesInternational Journal of Electrical Power & Energy Systems
Due to the wide application of modular multilevel converters (MMCs) in hybrid AC/DC distribution grids, enhancing the fault ride-through (FRT) capability of MMC is essential to improve the reliability of the hybrid AC/DC distribution grids. In this paper,

Elevator dynamic monitoring and early warning system based on machine learning algorithm

open access: yesIET Networks, EarlyView., 2022
In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Analysis of fault ride through in wind farms during network faults

open access: yesRE&PQJ
Fault Ride Through (FRT) is a term used todescribe the ability of wind farms to remain connected to the system during disturbances, such as short circuits or voltage drops. This capability is vital for maintaining the stability of power systems and preventing the adverse consequences that may arise from wind power outages during disturbances.

Using Deep Learning Conditional Value‐at‐Risk Based Utility Function in Cryptocurrency Portfolio Optimisation

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT One of the critical risks associated with cryptocurrency assets is the so‐called downside risk, or tail risk. Conditional Value‐at‐Risk (CVaR) is a measure of tail risks that is not normally considered in the construction of a cryptocurrency portfolio.

An Adaptive Series-Dynamic-Resistor-Based Protection Scheme for Brushless Doubly- Fed Induction Generator Under Asymmetrical Fault Conditions

open access: yesIEEE Access
Low-voltage ride-through (LVRT) is one of the most important criteria for integrating wind energy into the power grid. Based on grid connection codes, wind generators must remain connected during fault conditions.

Insider Ownership and Investment Efficiency

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines the relationship between insider ownership and investment efficiency in Indian publicly listed firms, utilising panel data spanning 2001 to 2015. It explores how agency conflicts contribute to suboptimal capital investment decisions. Our analysis reveals that increased insider ownership is associated with reduced investment
