A DFIG low- and High-Voltage cascading failure through strategy based on GSC and RSC joint control

International Journal of Electrical Power & Energy Systems
In wind power DC transmission systems, commutation failures cause significant reactive power fluctuations at the direct current (DC) transmission end, leading to sequential changes in voltage from low to high and often causing wind turbines to disconnect

Low-Voltage Ride-Through Technology in Photovoltaic Power Generation

Highlights in Science, Engineering and Technology
As global photovoltaic (PV) integration surges, the ramifications of PV systems on the power grid have become increasingly pronounced. When faced with grid disturbances or faults, the abrupt disconnection of PV systems can critically imperil grid stability.

Low Voltage Ride Through Characterization of Wind Energy Conversion Systems

RE&PQJ
Low Voltage Ride Through (LVRT) has emerged as an essential requirement that system operators demand to wind energy conversion systems (WECS). LVRT characterization is to get the minimum grid voltage profile under which the transient stability of WECS is not possible. This paper will determine the LVRT capability of existing Egyptian WECS.

Enhanced Control Strategies for Improving Low Fault Ride-Through Capability of Grid-Connected Doubly Fed Induction Wind Turbines

Energies
The DFIG faces challenges in providing fast and accurate support during grid voltage fluctuations. Severe voltage dips can trigger peak currents, which may damage the converter equipment and even lead to the disconnection of turbines from the grid.

The Degradation of Access‐Based Business Models: Customer Misbehavior and Shared Mobility

Business Strategy and the Environment, EarlyView.
ABSTRACT Access‐based services are considered one of the strategies to embed sustainability in business models. Yet, because the evolution of these business models has been overlooked, we do not know whether their promise to create triple value is sustained.

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

Business 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 ...
