Coordinated control of grid-following and grid-forming energy storage for virtual inertia response considering frequency modal characteristics

International Journal of Electrical Power & Energy Systems
Grid-following energy storage (GFL-ES) and grid-forming energy storage (GFM-ES) will coexist for a certain period into the future as one of the frequency regulation resources in low-inertia power systems.

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

Advanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Interactive Framework on Absorptive Capacity and Organizational Learning for Circular Economy Transition

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) requires organizations to move beyond linear production systems toward regenerative, resource‐efficient models. For small and medium‐sized enterprises (SMEs), this transition is especially demanding due to constrained financial, technological, and human resources.
