Environmental Regulation at the Crossroads: A Review of Catalysts and Barriers in Circular Economy Transitions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid growing resource pressures, environmental regulation plays a critical role in enabling the transition to a circular economy (CE). This study conducts a systematic literature review to synthesize how different regulatory approaches—command‐and‐control, market‐based, voluntary, and reflexive—affect CE transitions across economic and ...

Comprehensive fault ride‐through scheme for doubly‐fed induction generators

open access: yesThe Journal of Engineering, 2018
With the growth of wind energy penetration in electricity transmission grids, fault ride‐through (FRT) ability is required in order to maintain the uninterrupted operation of wind farm in voltage disturbance scenarios. For widespread used doubly‐fed induction generator FRT issues, an auxiliary hardware circuit is adopted in large‐grid‐voltage drop ...
