Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

A hidden Markov model and reinforcement learning‐based strategy for fault‐tolerant control

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study introduces a data‐driven control strategy integrating hidden Markov models (HMM) and reinforcement learning (RL) to achieve resilient, fault‐tolerant operation against persistent disturbances in nonlinear chemical processes. Called hidden Markov model and reinforcement learning (HMMRL), this strategy is evaluated in two case studies

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

From Custom to Court: The Evolution of Mediation in European Legal Systems

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article traces how European mediation has repeatedly rebalanced three variables—(1) the source of mediator authority, (2) the degree of institutionalization, and (3) the operative meaning of voluntariness—from antiquity to the present. Using three periods—Proto‐Mediation (c. 500 BCE–c. 1750), Classical Mediation (c.

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.

Designing Governance for ESG: Incentive and Oversight Complementarities in Corporate Sustainability Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates how internal governance design supports credible ESG performance by distinguishing between Incentive and Oversight Architectures. Using 13,993 firm‐year observations of US nonfinancial firms from 2018 to 2024, we estimate fixed effects and two‐step system GMM models.

Back-to-back Converter Control of Grid-connected Wind Turbine to Mitigate Voltage Drop Caused by Faults

, 2017
Power electronic converters enable wind turbines, operating at variable speed, to generate electricity more efficiently. Among variable speed operating turbine generators, permanent magnetic synchronous generator (PMSG) has got more attentions due to low
