Enhanced Crowbar Protection for Fault Ride through Capability of Wind Generation Systems [PDF]

open access: yes, 2016
Due to increasing demand in power, the integration of renewable sources like wind generation into power system is gaining much importance nowadays. The heavy penetration of wind power into the power system leads to many integration issues mainly due to ...

Validated Signalling: How Ownership Structure Enhances ESG Disclosure Credibility in an Emerging Market

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT While signalling theory predicts that ESG disclosure reduces information asymmetry and supports forward‐looking firm valuation, this relationship remains contested in emerging markets with concentrated ownership. Using a panel of 84 Turkish listed firms over 2014–2024 (924 firm‐years) and two‐step system GMM, we examine whether business groups,

Low-Voltage Ride-Through Capability of a Single-Stage Single-Phase Photovoltaic System Connected to the Low-Voltage Grid

open access: yesInternational Journal of Photoenergy, 2013
The progressive growing of single-phase photovoltaic (PV) systems makes the Distribution System Operators (DSOs) update or revise the existing grid codes in order to guarantee the availability, quality, and reliability of the electrical system.

Using Machine Learning to Predict Corporate Environmental Violation: A Stakeholder Pressure Perspective

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Predicting corporate environmental violations remains a key challenge in practice and in environmental governance research. However, existing studies have largely focused on ex post associations between stakeholder pressures and realized environmental violations, offering limited insight into whether stakeholder pressures can be used ex ante ...

Carbon Markets and Green Innovation: Path‐Dependent Firm Responses to Emissions Trading

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper identifies a dynamic boundary condition of the Porter hypothesis by examining how firms' pre‐existing innovation trajectories shape regulatory‐induced green innovation within the context of a market‐based carbon policy. Building on path dependency theory, we argue that firms' responses to environmental regulation are contingent on ...

Fault Ride-through Capability of Grid Integrated Solar Power Plants [PDF]

open access: yes, 2015
Decreasing costs and increasing efficiency of solar panels has led to the emergence of multi-MW Solar Power Plants (SPP). Grid codes now require an SPP to remain connected and provide reactive power support to the grid during a fault.

Impact Risk in Impact Investing: A Systematic Review of Impact Risk Drivers and Governance Responses and an Integrative Framework

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study systematically reviews impact risk in impact investing to identify its dimensions, drivers, governance responses, and interrelationships. Drawing on a qualitative thematic analysis of 56 articles published between 2011 and 2025, the review integrates previously fragmented research on impact‐related risks.
