TL;DR: In this article, a procedure for adequately modeling series capacitors protected by metal oxide varistor (MOV) in a conventional short-circuit program is proposed, which uses a quasi-linear model to represent the nonlinear characteristic of the MOVs, combined with a compensation technique to represent intersequence coupling during unbalanced faults.
Abstract: A procedure for adequately modeling series capacitors protected by metal oxide varistor (MOV) in a conventional short-circuit program is proposed. It uses a quasi-linear model to represent the nonlinear characteristic of the MOVs, combined with a compensation technique to represent the intersequence coupling during unbalanced faults. The effectiveness of the method, which is valid for unbalanced as well as balanced faults, is demonstrated by comparing the results with those obtained using time-domain simulations. The results show that the proposed procedure can adequately and efficiently model MOV-protected series capacitors in a standard short-circuit program. >

TL;DR: In this article, the Gibbs energy expressions were also presented in the form of interaction parameters, and the equivalence between the polynomial and interaction parameter formalisms was discussed, through the Kohler equation or the modified interaction parameters formalism, the thermodynamic properties of the multicomponent solution of 18 elements in molten Sn can be calculated.
Abstract: Thermodynamic and phase equilibrium data for the following 18 elements in molten Sn were collected and critically evaluated: Al, Ca, Ce, Co, Cr, Cu, Fe, H, Mg, Mo, Na, Ni, O, P, S, Se, Si, and Ti. Binary and ternary data were optimized to give polynomial expressions for the excess Gibbs energies as functions of temperature and composition. For some solutes, the optimized expressions are valid over the entire composition range 0 ≤ XSn ≤ 1. In other cases, the expressions apply to Snrich solutions. Solute-solute interaction terms were estimated where data were not available. The optimized Gibbs energy expressions are also presented in the form of interaction parameters, and the equivalence between the polynomial and interaction parameter formalisms is discussed. Through the Kohler equation, or the modified interaction parameter formalism, the thermodynamic properties of the multicomponent solution of 18 elements in Sn can be calculated. The database is suitable for computer storage and manipulation.

TL;DR: In this article, a manganese hydride molecular sieve was synthesized from inexpensive precursors and demonstrated a reversible excess adsorption performance of 10.5 wt% and 197 kgH2 m−3 at 120 bar at ambient temperature with no loss of activity after 54 cycles.
Abstract: A viable hydrogen economy has thus far been hampered by the lack of an inexpensive and convenient hydrogen storage solution meeting all requirements, especially in the areas of long hauls and delivery infrastructure. Current approaches require high pressure and/or complex heat management systems to achieve acceptable storage densities. Herein we present a manganese hydride molecular sieve that can be readily synthesized from inexpensive precursors and demonstrates a reversible excess adsorption performance of 10.5 wt% and 197 kgH2 m−3 at 120 bar at ambient temperature with no loss of activity after 54 cycles. Inelastic neutron scattering and computational studies confirm Kubas binding as the principal mechanism. The thermodynamically neutral adsorption process allows for a simple system without the need for heat management using moderate pressure as a toggle. A storage material with these properties will allow the DOE system targets for storage and delivery to be achieved, providing a practical alternative to incumbents such as 700 bar systems, which generally provide volumetric storage values of 40 kgH2 m−3 or less, while retaining advantages over batteries such as fill time and energy density. Reasonable estimates for production costs and loss of performance due to system implementation project total energy storage costs roughly 5 times cheaper than those for 700 bar tanks, potentially opening doors for increased adoption of hydrogen as an energy vector.
