With solar energy being abundantly available in most part of the country, grid connected solar power plants are assuming increasing importance. Energy fed into grid by a solar power plant depends upon seasonal variation of the solar resources, system losses, and losses due to condition of the grid. This paper presents performance analysis of solar power plant installed in Madhya Pradesh. Daily and seasonal variation in the solar power plant output are shown using monitored data, the SPV generation in relation to load duration curve of substation is observed. Since the cost of electricity generated from solar is still expensive and also the power from renewable resources including solar is infirm power, large scale development of renewable resources did not take place and distribution utilities are also least interested to purchase power from renewable sources.

The estimates were based on the performance data of the individual units over a period of one year. The power produced by the wind turbine increases from zero at the threshold wind speed (cut in speed) (usually around 5m/s but varies with site) to the maximum at the rated wind speed. Above the rated wind speed, (15 to 25 m/s) the wind turbine continues to produce the same rated power but at lower efficiency until shut down is initiated if the wind speed becomes dangerously high, i.e. above 25 to 30m/s (gale force). The exact specifications for energy capture by the turbine depend on the distribution of wind speed over the year at the individual site.

Taking in to account the temperature and sun’s irradiance, the PV array is modeled and its voltage current characteristics and the power and voltage characteristics are simulated. This enables the dynamics of PV system to be easily simulated and optimized. It is noticed that the output characteristics of a PV array are influenced by the environmental factors and the conversion efficiency is low. Therefore a maximum power tracking (MPPT) technique is needed to track the peak power to maximize the produced energy. The maximum power point in the power–voltage graph is identified by an algorithm called perturbation & observation P&O) method or Hill climbing. This algorithm will identify the suitable duty ratio in which the DC/DC converter should be operated to maximize the power output. The results confirm that the photo voltaic array with proposed MPPT controller can operate in the maximum power point for the whole rang...

This is due to very limited fossil fuel resources and poor economy, which restrains the import of fossil fuels on a large scale. To overcome energy shortage, India needs to develop its indigenous energy resources like hydropower, solar and wind. India lies in an area of one of the highest solar insulation in the world. Accordingly, the status and outlook of solar energy use in India are discussed. It is concluded that the current infrastructure has not been able to advance the status of solar energy in India. Significant efforts are needed to effectively utilize this cheap renewable energy source. Solar power is a term that refers to several alternative sources of energy by which sunlight is harnessed to do useful work for mankind.

Different types of ribs were used inside the solar air heater to create turbulence near the absorber plate that is at the top face of solar air duct. For analyzing the effect of different shapes of ribs used inside the solar air heater, here in this work it considered four different types of ribs that are rectangular, triangular, circular and hexagonal. With each shape of ribs, effect of change in Reynolds number was also analyzed. For measuring the heat transfer enhancement here it calculates the value of Nusselt number and for pressure drop it calculates the friction factor. Ansys Fluent model was used to analyze the flow behavior of air inside the solar air heater an...

This is due to very limited fossil fuel resources and poor economy, which restrains the import of fossil fuels on a large scale. To overcome energy shortage, India needs to develop its indigenous energy resources like hydropower, solar and wind. India lies in an area of one of the highest solar insulation in the world. Accordingly, the status and outlook of solar energy use in India are discussed. It is concluded that the current infrastructure has not been able to advance the status of solar energy in India. Significant efforts are needed to effectively utilize this cheap renewable energy source. Solar power is a term that refers to several alternative sources of energy by which sunlight is harnessed to do useful work for mankind. People know that it is energy since the same alone implies this, but many people think it is expen...
