Stand-alone photovoltaic (PV) systems comprise one of the most promising electrification solutions for covering the demand of remote consumers. However, such systems are strongly questioned due to extreme life-cycle (LC) energy requirements. For similar installations to be considered as...

Hybrid wind-diesel systems are an interesting solution for the electrification of isolated consumers. The proposed system, including a properly sized battery, leads to a significant reduction of the fuel consumption, in comparison with a diesel-only installation, also protecting the diesel...

A large number of various sized islands are spread throughout the south-east Mediterranean Sea. Most of these small islands face serious infrastructure problems, like the insufficient power supply and the low quality of electricity available at very high production cost. In an attempt to improve...

The high wind and solar potential along with the extremely high electricity production cost met in the majority of Greek Aegean islands comprising autonomous electrical networks, imply the urgency for new renewable energy sources (RES) investments. To by-pass the electrical grid stability...

Although development of renewable energy sources (RES) projects is essential for the Greek national economy to revive, cut downs of public spends in Greece may equally well extend to affect RES support mechanisms. In this context, an integrated cost–benefit analysis is currently undertaken...

Maturity of the photovoltaic (PV) technology is emphasized by the numerous types of applications encountered nowadays. One of the most interesting applications, however, is the use of PV units for pumping water, i.e. the implementation of PV pumping systems (PVPSs) in order to cover both...

Renewable energy sources (RES) based stand-alone systems employing either wind or solar power and energy storage comprise a reliable energy alternative, on top of conventional diesel-electric generator sets, commonly used by remote consumers. However, such systems usually imply the need for...

The main aim of the specific research is the comparison of the energy pay-back period of optimum renewable energy sources (RES)-based configurations, meaning wind-battery and photovoltaic-battery stand-alone installations that may ensure the energy autonomy of a typical remote consumer under the...

Wind parks operating in autonomous island grids, such as those encountered in the Aegean Archipelago, face considerable wind energy curtailments, owed to the inability of local electricity networks to absorb the entire wind energy production. On the other hand, plans promoting the natural...
