Mallapragada, Dharik S. Ph.D., Purdue University, December 2013. Energy Systems Analysis for a Solar Economy. Major Professor: Rakesh Agrawal. The use of solar energy for human needs faces challenges owing to its relatively low energy intensity and intermittent availability, coupled with the constrained availability of renewable carbon and land resources. This study uses systems analysis tools ...

Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...

Ground thermal energy as a clean and sustainable energy source has received significant attention lately. Several strategies and hybrid configurations have been proposed to harvest geothermal energy for air conditioning and industrial purposes. The possibility of moist soil freezing in the vicinity of borehole tubes is known to be the source of several benefits and difficulties. The high storag...

Hybrid power system can be used to reduce energy storage requirements. The influence of the Deficiency of Power Supply Probability (DPSP), Relative Excess Power Generated (REPG), Energy to Load Ratio (ELR), fraction of PV and wind energy, and coverage of PV and wind energy against the system size and performance were analyzed. The technical feasibility of PV-wind hybrid system in given range of...

Abstract Resolving the power crises requires combination of different individual renewable energy sources so that one source can compensate for another. Unfortunately, are not always available at certain times making their use problematic. To solve this uncertainty, it is important to combine independent and determine right set mix economical reliable. The data solar PV, wind, battery, biomass....

We present a further investigation into the increased ionization observed in element charge states in the fast solar wind compared to its coronal hole source regions. Once ions begin to be perpendicularly heated by ion cyclotron waves and execute large gyro-orbits, density gradients in the flow can excite lower hybrid waves that then damp by heating electrons in the parallel direction. We give ...

The purpose of this study was to determine the performance a hybrid dryer by combining utilization solar energy (solar dryer) and biomass power sources. Utilization thermal sources maximizing heat radiation which are absorbed directly into drying chamber in form transparent house with ventilation holes for fresh air enter moist exit. This process will produce hot circulation (convection) contin...

Hybrid system based on photovoltaic is considered an effective option to electrify remote and isolated areas far from grid. This is true for areas that receive high averages of solar radiation annually. Using diesel generator as a standby source will make utilization of hybrid systems more attractive. An economic feasibility study and a complete design of a hybrid system consisting of photovolt...
