Energy resources for rural electrification are variable and widely dispersed, such that a solution for one region might not be appropriate for another. This study evaluates the feasibility of renewable energy technologies, centralized grid extension and local coal-fired power for rural areas...

Anaerobic digestion is increasingly recognized for its ability to produce renewable energy and reduce greenhouse gas emissions from livestock operations. In 2010, there were 2645 U.S. dairy farms with herd sizes large enough to support anaerobic digesters, yet only 156 systems were in operation...

Nowadays, as set by the EU 20-20-20 targets, the reduction of primary energy use and greenhouse gas emissions in the energy sector can be attained by increasing the use of renewable sources and improving energy efficiency. Many national and international research programs are aiming at...

The global demand for energy is currently growing beyond the limits of installable generation capacity. To meet future energy demands efficiently, energy security and reliability must be improved and alternative energy sources must be investigated aggressively. An effective energy solution...

This paper presents a method for evaluating investments in decentralized renewable power generation under price un certainty. The analysis is applicable for a client with an electricity load and a renewable resource that can be utilized for power generation. The investor has a deferrable...

This paper presents a passive islanding detection method for wind turbines. The proposed method is based on voltage measurements and processing of this voltage with a discrete wavelet transform. This method detects the islanding conditions with the analysis of Daubiches wavelets. The studies...

Nowadays the use of distributed generating systems, which use a renewable energy source, has experienced a fast development. Moreover their intrinsic intermittent nature can be overcome using hybrid systems which combine more energy sources. This paper discusses the main topologies which can be...
