Non-negativity and capacity constraints on accumulation, and price floors, have particular relevance for water, oil, gas, electricity, and other energy commodities. Such constraints are empirically relevant; even if ...

Understanding how tropical montane catchments store and release water, and the resulting water ecosystem services they provide is crucial for improving water resource management. But while research in high–elevation tropical ...

A computationally efficient numerical model is developed in this study for evaluating the dynamic behavior of liquid storage tanks. This model has higher complexity than the Housner model (which corresponds to the simplest ...

In this paper, the dynamic modeling and the control design of hybrid energy storage system based on compressed air and supercapacitors (CAES-SC) is presented, which converts excess energy from the power supply to stored ...

Apresentação do palestrante Hélyette Geman - Commodity Finance Centre, University of London and ESCP Europe no contexto do evento "The Economics and Econometrics of Commodity Prices". Mais informações em: <http://epge.fg ...

A new model is developed to analyze oxygen interference in hydrogen storage materials. It is based on the competitive adsorption isotherm between the two gases, with the parameters fitted from molecular dynamic simulations. ...

The main problem of renewable energy power plants is the intermittency of the source of energy. Therefore, instantaneous variations of power demand could not be properly recovered. For overcoming this problem, the best ...

Sedimentary plains with extremely flat topography, such as the Pampas in Argentina, often display flooding–drought cycles.Changes in water table depth and surface water coverage affect natural and cultivated vegetation, ...

The growing penetration of low-carbon technologies in residential networks such as photovoltaic generation (PV) units and electric vehicles (EVs) may cause technical issues on the grid. Thus, operation planning of electrical ...
