Techno‐Economic Analysis of Solar‐Wind Hybrid Systems for Green Hydrogen Production in South Africa, KwaZulu‐Natal Province

Energy Science &Engineering, EarlyView.
ABSTRACT Rising global energy demand and the climate crisis have intensified the pursuit of renewable energy, with green hydrogen emerging as a key alternative to fossil fuels. South Africa, heavily reliant on coal‐based energy, faces pressure to decarbonize and transition to a green economy.

Characterization of Multimodality in Wind Farm Layout Optimization

Energy Science &Engineering, EarlyView.
ABSTRACT The phenomena of multiple optima in wind farm layout optimization (WFLO) problems is investigated. The choice of optimization algorithm and cost of solving WFLO problems is driven by the degree of local optimality in the design space; however little work has attempted to characterize this.

Comparative Numerical Studies for the Flow Energy Dissipation Features in a Vertical Two‐Stage Centrifugal Pump in Pump and Turbine Conditions

Energy Science &Engineering, EarlyView.
Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

Data‐Driven Dual‐Channel Dynamic Event‐Triggered Load Frequency Control for Multiarea Power Systems Under DoS Attacks

Energy Science &Engineering, EarlyView.
ABSTRACT System dynamics uncertainties and cyberattacks pose significant challenges to load frequency control in power systems. This paper presents a data‐driven load frequency control strategy for interconnected multi‐area power systems subject to denial‐of‐service attacks that disrupt both feedforward and feedback communication channels.
