A successive linear programming methodology is presented to treat more effectively those applications where a local structure change performed power system already in operation, and the modification of settings existent relays not desirable. The dimension optimization problems be solved substantially reduced, sequence small stated terms time dial settings, until feasible solution reached. With proposed technique, number original reset reduced substantially. It found that there trade-off...
Renewable hydrogen offers a promising pathway to address the challenge of large-scale chemical energy storage in transition decarbonized future. The most efficient devices convert renewable electricity into hydrogen, and vice versa, are reversible solid oxide cells (SOC-s). Despite recent advances materials performance durability, conventional ceramic manufacturing technologies strongly limit huge potential SOC-s, imposing severe geometrical restrictions that penalize overall system...
Solid Oxide Cells are highly efficient energy conversion devices for power generation, in fuel cell mode, and storage, electrolysis mode. This multi-layer ceramic device is currently fabricated with state-of-the-art manufacturing processes such as tape casting screen-printing. Alternatively, 3D printing technologies stereolithography or robocasting have demonstrated their potential to fabricate enhanced electrochemical cells by employing an additive approach able create complex shapes,...
Mechanically coupled resonators have been applied in the last years to development of nanomechanical mass-sensors based on detection different vibration modes system by measuring a single resonator.
