Extracting Maximum Power from Photovoltaic System using MPPT Techniques

Abstract — In this paper for control of photo-voltaic power by utilization of a boost converter using Maximum Power Point Tracking (MPPT) control mechanism is presented. The MPPT is responsible for extracting the maximum possible power from the photo-voltaic and feed it to the load via the boost converter which steps up the voltage to required magnitude. The main aim will be to The main aim will be to extract maximum power from the photo-voltaic so its necessary to continuously track maximum power point of the photo-voltaic module. The MPPT basically works on an algorithm. The algorithms are usually written in m files of MATLAB and utilized in simulation

Electricity from Rice Husk A Potential & Eco- friendly Way to Electrify India

as per reports it can be stated that the energy demanded by India is continuously increasing day-by-day. For the sake of providing energy security the amount of fossil fuels imported is quite high. With this, in fossil fuel there are several components like CO2, SO2 and NOX which presents an adverse effect to the environment. To find an alternative solution to this big problem and arrive to a satisfactory result, re-usable (renewable) energy sources are needed to be developed. In India the Rice is grown in a very large quantity and it holds a considerable rank in exporting to the rest of the countries, here rice husk is a potential source of energy. To produce energy the Rice mills can utilize rice husk produced by them. However, the energy produced must be such that leads minimum damage to the environment. In coal and oil-fired power generation have a lesser amount of SO2 and NOX emission, but higher than for natural gas. In this process the CO2 obtained from combustion of rice husk is taken as zero as it does not contribute to global warming. The CO and dust emissions are comparatively higher than the conventional power production pointing which is required for improving the combustion efficiency of the rice husk power plant. Overall, it suggests that rice husk will be successful feedstock to produce electricity and works well than fossil fuels (basically coal and oil) from the view of environmental emissions. Electrical energy generation of a country determines it’s economic development. Thus to compete other developed countries, India must have more than required electrical generation technique so that it can pace up the developmental process. To get development India has to, make the electricity available to most possible doors

Solar Thermal Power Technology

Generally energy is available in two forms i.e. non renewable and renewable energy sources. Several environmental issues are related with the use of conventional energy sources like coal, petroleum and natural gas and different type of advantages or benefits offered by non conventional energy sources like solar, wind and small hydro included. Solar technology from history point of view is very old i.e. from 7th century B.C. to today. But in recent years the attention is more focused on solar energy for generate electricity. Solar energy help us to reduce the use of fossil fuel. Solar technology is a pollution free technology, so this technology is called by green technology. Solar energy can be used in two ways one of which is solar photovoltaic and another one is solar thermal and this paper is based on the review of solar thermal energy
