Harnessing renewable energy sources (RES) using hybrid systems for buildings is almost a deontological obligation engineers and researchers in the field, increasing percentage of renewables within mix represents an important target. In crowded urban areas, on-site production storage from can be real challenge technical point view. The main objectives this paper are quantification impact consume...

Data envelopment analysis (DEA) is a method for measuring the relative efficiencies of a set of decision-making units (DMUs) that use multiple inputs to produce multiple outputs. In this paper, we study the measurement of DMU performances in DEA in situations where input and/or output values are given as imprecise data. By imprecise data we mean situations where we only know that the actual val...

In order to solve the problem of energy consumption, improve efficiency utilization and develop new energy, total consumption fluctuation thermal integrated were analyzed. Four suggestions are put forward for power system flexible plant, namely, electric heat storage system, pump g, heating high pressure via steam turbine, which can air capacity reduce coal system. Among them, in case small con...
