A Generalized Load Model Considering the Fault Ride-Through Capability of Distributed PV Generation System

Energies
Considering the voltage stability problem brought by large-scale distributed PV access to the distribution network, this paper proposes a generalized load model that considers the fault ride-through capability of distributed PV.

Voltage dip generator for testing wind turbines connected to electrical networks [PDF]

, 2011
This paper describes a new voltage dip generator that allows the shape of the time profile of the voltage generated to be configured. The use of this device as a tool to test the fault ride-through capability of wind turbines connected to the electricity

From ESG to Biodiversity: Decoupling and Its Asymmetries as a Source of Biodiversity Risk

Business Strategy and the Environment, EarlyView.
ABSTRACT While environmental, social and governance (ESG) research has extensively documented the risks stemming from disclosure and performance gaps, the growing demand for biodiversity reporting raises concerns that analogous inconsistencies may amplify corporations' exposure to biodiversity risk.

A modular DC transformer with DC fault ride-through capability

Journal of Physics: Conference Series
Abstract DC transformers are core equipment for constructing multi-voltage-level DC distribution networks. However, mainstream DC transformer topologies, which are based on the Input-Series Output-Parallel Dual Active Bridge (ISOP-DAB), currently have deficiencies in fault blocking capability and fault-tolerant redundancy design.

Control of Brushless Doubly-Fed Reluctance Machines under Normal and Faulty Operating Conditions [PDF]

The brushless doubly fed reluctance machine (BDFRM) is an attractive alternative technology to traditional slip-ring doubly fed induction machine (DFIM) for slip-power recovery applications with limited variable speed ranges such as wind turbines or pump-

The Greenwashing Gambit: A Double‐Edged Sword in Crowdfunding Success

Business Strategy and the Environment, EarlyView.
ABSTRACT The paper examines when greenwashing becomes a success factor in reward‐based crowdfunding campaigns aimed at financing environmentally sustainable products. While prior work has identified what drives success in such campaigns, it remains unclear when misleading environmental claims are discounted as cheap talk and when they instead ...

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.

When and How Do Women Directors Matter for Corporate Sustainability? The French Case

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines when and how board gender diversity matters for corporate sustainability. Using a sample of French listed firms over 2006–2024, we combine dynamic system GMM estimations with difference‐in‐differences tests around France's phased board gender quotas.

Fault ride-through of renewable energy conversion systems during voltage recovery

Journal of Modern Power Systems and Clean Energy, 2016
Asymmetrical voltage swells during recovery of a short-circuit fault lead to fluctuations in the dc-link voltage of a renewable energy conversion system (RECS), and may induce reversed power flow and even trip the RECS. This paper studies characteristics
