Analysis of fault ride through in wind farms during network faults

RE&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

International 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

IEEE 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

International 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

Comparative Performance Evaluation of Wind Energy Systems Using Doubly Fed Induction Generator and Permanent Magnet Synchronous Generator

Wind
Wind energy has become a cornerstone of sustainable electricity generation, yet the reliable integration of wind energy conversion systems (WECSs) into modern grids remains challenged by dynamic variations in wind speed and stringent fault ride-through ...

Land Use Policy and Racial Segregation

International Studies of Economics, EarlyView.
ABSTRACT Land use policies, though seemingly race‐neutral, can inadvertently contribute to racial segregation. Our study focuses on examining the impact of minimum lot size regulations on the likelihood of ethnic minorities integrating into a community, which reveals compelling evidence suggesting that black households exhibit a preference for smaller ...

Evaluating the efficacy of psychological therapies for generalised anxiety disorder in children and adolescents: A systematic review and narrative synthesis

JCPP Advances, EarlyView.
Abstract Background Generalised Anxiety Disorder (GAD) is common in children and adolescents, and if not successfully treated, has negative consequences for their current and subsequent mental health. Whilst psychological therapies have previously been assessed in terms of their efficacy for a combination of anxiety disorders, no existing systematic ...

Does Mobile Money Adoption Improve Dietary Quality? Assessing Household and Individual Level Impacts in Cameroon

Journal of International Development, EarlyView.
ABSTRACT Mobile money—a digital financial service—has proliferated in many developing countries. Owing to its ability to reduce transaction costs and allow even the poor to be financially included, it has been widely adopted. While a growing body of literature has examined its welfare effects, its effects on diet quality of households and individuals ...
