The use of renewable energy sources (RESs) is a need global society. This editorial, and its associated Special Issue “Grid-Connected Renewable Energy Sources”, offer compilation some the recent advances in analysis current power systems composed after high penetration distributed generation (DG) with different RESs. focus on both new control configurations novel methodologies for optimal place...

Cellular networks are now rapidly evolving to the renewable heterogeneous network (HetNet) architectures, where a mixture of macro base stations (BSs) and small cell BSs coexist. Particularly, these BSs are partly-powered or self-powered by renewable energy sources (RES). In this context, joint user association and resource allocation is challenging. In addition, wireless backhaul is rapidly be...

This article looks at one way of harnessing inexhaustible energy - wind power. The relevance the use farms has been considered, which is due to many factors. most important advantage an source energy, namely air currents, are result pressure differences in atmosphere. Although modern industry mainly based on non-renewable sources (oil, gas and hard coal account for about 80% global balance), in...

Renewable sources are not used to their full potential for electricity generation. Unpredictability of solar and wind power forces renewable generators to bid conservative generation amounts in a dayahead market in order to avoid fees for failure to provide generation. In this paper we propose an approach to increase the use of renewable sources, which allows renewable generators to hedge again...

abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...

Over the last decade, it has been considerable attempts to replace thermal power plants by renewable energy sources (RESs), mainly to reduce harmful gaseous emissions. Ubiquitous nature of these sources in the emerging smart grid, demands a dominated RES power system for a long-term horizon. This study proposed a model for 100% RES-based system which is tractable and flexible enough to be used ...
