The combination of the remote-area-diesel generators with a battery storage and renewable energy source such as photovoltaic (PV) can greatly overcome the problems of these generators. In this paper a PV/Diesel generator hybrid energy system is sized to meet the load for about 100% availability. Where, for a given load characteristic and a given diesel generator a methodology is developed to op...
A better performance of photovoltaic (PV) generator is obtainedat high insolation. But at high insulation, the temperature of the PV system increases and leads to the drop down of the performance of the system making the system unable to supply the load. The problem becomes more difficult with irregular solar insolation, the system experience variation in his output, which is not good for the u...
Solar energy has become an important energy source in recent years as it generates less pollution than other energies. A photovoltaic (PV) system, which typically has many components, converts solar energy into electrical energy. With the development of advanced engineering technologies, the transfer efficiency of a PV system has been increased from low to high. The combination of components in...
Renewable energy sources i.e.,energy generated from solar, wind, biomass, hydro power, geothermal and ocean resources are considered as a technological option for generating clean energy. But the energy generated from solar and wind is much less than the production by fossil fuels, however, electricity generation by utilizing PV cells and wind turbine increased rapidly in recent years. This pap...
Renewable energy is derived from natural processes that are replenished constantly. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and bio-fuels and hydrogen derived from renewable resources. Each of these sources has unique characteristics which influence how and where they are used. This paper presents the model...
This paper presents a novel strategy, optimized by genetic algorithms, to control stand-alone hybrid renewable electrical systems with hydrogen storage. The strategy optimizes the control of the hybrid system minimizing the total cost throughout its lifetime. The optimized hybrid system can be composed of renewable sources (wind, PV and hydro), batteries, fuel cell, AC generator, and electrolyz...
Hybrid photovoltaic/thermal (PV/T) collector, combining photovoltaic cells with a solar thermal collector, can simultaneously convert solar energy into electricity and heat energy. In this paper, a novel photovoltaic/thermal integrated heat pump (PV/T-HP) system was developed, in which the PV/T collector also acted as evaporator of heat pump. Two types of PV/T collectors with conventional coppe...
This project deals with a grid connected wind-PV hybrid distributed generation system employing permanent magnet synchronous generator(PMSG) driven by a variable speed wind turbine and PV array connected to a load and the grid. PMSG wind turbine connected to a dc-dc converter via three phase diode rectifier and PV array along with a dc-dc converter connected to the DC link which operates under ...
