Statistical analysis of solar-wind-biomass hybrid system installed at R.G.T.U., Bhopal M.P., India.

ABSTRACT This article describes the linkage that exists among the various alternative power sources in the hybrid system. The wind energy system, along with solar photovoltaic panels and a biomass gasifier for the production of electricity, is more suitable among the alternatives available. Wind, solar and biomass energy systems can be used in remote areas. Keeping this in mind, a statistical analysis of the hybrid energy system has been developed for a remote area. Wind and solar data are obtained from a weather monitoring station installed at Energy Park, R.G.T.U., Bhopal, India.

Role of Thermo - Electric Generator in Recovery of Waste Heat of Automobile

Today world is facing lots of problem regarding energy crisis and thermal energy management. As we know that Environmental pollution has been more emphasized heavily recently and in Internal combustion engine, The engine exhaust has a tremendous amount of energy and out of Total heat supplied to the engine in the form of fuel approximately 30-40% converted into useful work and the remaining one is expelled in the form exhaust gases and this exhaust gases can be recovered by using waste heat recovery system. Thermo electric principle can be used for recovering waste heat and convert into useful work by using See back effect by creating potential difference. The study shows the possible methods to recover waste heat energy from engine exhaust of an Automobile and techniques to maximize energy efficiency. Viewing from socioeconomic perspective, as the level of energy consumption is directly proportional to the economic development and total number of population in the country, the growing rate of population in the world today indicates the energy demand is likely to increase [1].

EXPERIMENTAL INVESTIGATION, OPTIMIZATION AND PERFORMANCE PREDICTION OF WIND TURBINE(S) FOR COMPLEX TERRAIN

Man has been doing business with Winds since a very long period of time; the wind power has been used as long as humans have put sails into the wind. For more than two millennia wind powered machines have ground grain and pumped water. This affiliation of man and wind is inexhaustible which makes Wind Energy a very significant and rapidly developing renewable energy sources in all over the world. But when it comes to electricity generation by harnessing the wind energy, indeed, it requires more technicality, since it requires a great need for correct and reliable installations of new wind turbines in a more optimized way for smooth operations and electricity productions, and for that, a precise knowledge of wind energy regime is a prerequisite for the efficient and optimized extraction of power from the wind. The main purpose of this paper is to present, in brief, wind potential and to perform an investigation on wind flow characteristics at RGPV Hill Top. In this work the recorded time series wind data for a period of five months as from july-2013 to November-2013 at the heights of 20 meters and 40 meters was fetched and analyzed for studying the observed wind climate, which was recorded by the NRG Symphonie Data logger wind mast installed at Energy Park, RGPV campus with an fixed averaging interval of 10 minutes, the analyzed data which was worked upon comprises of wind speed data in meter per second and its direction of flow in degrees. As a part of this work, the Wind Atlas Analysis and Application Program (WAsP) was employed to predict average mean-wind speeds for all directions for some desired sites. The influences of roughness of the terrain, for the area were also taken into consideration, followed by the vector map of the area. These data were analyzed using WAsP software and regional wind climate of the area was determined, leading to a wind resource map of the whole site, providing crucial details which helped in selecting the proposed turbine sites. Also, the AEP for the two already installed turbines was calculated.

Statistical analysis of solar-wind hybrid system using SYSTAT software

Energy plays an indispensable role in modern society. We all depend on a constant and reliable supply of energy - for our homes, businesses and for transport. Most of the renewable energy comes either directly or indirectly from sun and wind and can never be exhausted. It can be expected that possible applications of hybrid systems could be considered for the efficient utilization of these resources round the year together with possibilities of obtaining Carbon credits in the Carbon Trading. In this research paper, experimental data consisting of hourly records over a specified period were recorded in the Energy Park of UIT-RGPV Bhopal for a 1.6.kW SPV- Wind Hybrid System and Feasibility analysis is done using SYSTAT software.
