Forecasting of weather conditions such as solar irradiance and wind speed and direction is essential for efficient integration of solar and wind power into the energy portfolio. Several metrics can be used to evaluate forecast effectiveness: consistency, quality, and value [1]. Consistency refers to the correspondence between the forecast and the judgments made by forecasters to determine the f...

We consider the problem of characterizing the locational marginal value of energy storage capacity in electric power networks with stochastic renewable supply and demand. The perspective taken is that of a system operator, whose objective is to minimize the expected cost of firm supply required to balance a stochastic net-demand process over a finite horizon, subject to transmission and energy ...

Purpose The overarching theme is the importance of innovations that are created within the emerging economies. More specifically, the article looks at the development of various alternatives to vehicles powered by the internal combustion engine, new energy vehicles (NEVs) within China. Design/methodology/approach The broad strategic approach of two sectors within the NEV sector in China, the pu...

The paper presents background infornatien, rationale, description, and evaluation of an energy education program used with preschool and kindergarten children and their families. The objective is to describe the use of combined concepts of education, economics, and early childhoodiiin developing a value conscious approach to energy 'education. The paper is divided into four parts. Part I emphas...

The energy of a graph is the sum of the singular values of its adjacency matrix. A classic inequality for singular values of a matrix sum, including its equality case, is used to study how the energy of a graph changes when edges are removed. One sharp bound and one bound that is never sharp, for the change in graph energy when the edges of a nonsingular induced subgraph are removed, are establ...

energy is one of major factors of productions in all of economic sectors, which have important effect on a country economy. the effect of increasing price of energy carriers on productions of economic sectors is inevitable. therefore, this research was conducted by using the input - output model and product forecasting. the study investigated the latest available input - output table in 1385. t...

in this paper, the mean value of strain energy density criterion has been used to predict the critical fracture load in specimens with u-shaped notch under bending loads. an equation for calculation of averaged strain energy density in this zone has been presented. bending loads under mode i have been considered. two cases have been studied: 1) the control volume only includes the semicircular ...
