The maximum exploitation of local renewable energy sources is a key feature of DG (Distributed Generation) systems: to this aim, HPSs (Hybrid Power Systems), integrating renewable and non-renewable power sources with local energy storage may represent an effective solution, although they may...

Batteries in conventional fuel cell-based backup power systems carry out secondary tasks to support fuel cells in transient states. In this work, batteries fulfill an additional function: contributing to supply the load in stationary state, thus widening possibly the range of economical backup...

Within the field of Distributed Generation (DG), stand-alone Hybrid Power Systems (HPS) are a suitable solution to provide energy to isolated facilities where the connection to a centralized grid is not affordable. The logical evolution of such systems involves the optimization of power...

Several technologies are being used in distributed generation applications with variable degree of success. Among those are: wind turbines, small-scale hydropower plants, biomass, microturbines, photovoltaic arrays, and fuel cells. A fuel cell is a device that converts the chemical energy of...

The distributed generation (DG) of combined heat and power (CHP) for commercial buildings is gaining increased interest, yet real-world installations remain limited. This lack of implementation is due, in part, to the challenging economics associated with volatile utility pricing and potentially...

This work analyses the impact of different support schemes on the retail price of micro-combined heat and power units based on solid oxide fuel cells in the residential sector. The implications of each incentive toward the technical implementation of the technology are also analyzed.

The key issue to the widespread of distributed generation (DG) is the ability to safely, reliably and economically interconnect new energy sources with the existing distribution network 'utility grid'. With the rising prices of petroleum fuel sources, a high expected penetration of renewable...

El objetivo de este trabajo es analizar el potencial de instalacion de fuentes de energias renovables (eolica y mini-eolica) en explotaciones individuales y comunidades de regantes espanolas en base a un nuevo marco normativo de tarificacion electrica (medicion neta o generacion distribuida). Se...

The world is witnessing a transition from its present centralized generation paradigm to a future with increased share of distributed generation (DG). Integration of renewable energy sources (RES) based distributed generators is seen as a solution to decrease reliance on depleting fossil fuel...

The smart grid (SG) as a research area is advancing dealing with a wider range of topics such as power systems, energy generation and telecommunication. The conventional utility grid is used to operate in a passive mode absorbing energy from the substations and delivering it to the customers....
