Solar Wind Hybrid Power System
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAs the world progresses in the field of technology the need of green energy clean energy is becoming more and more important because of the unchecked use of the fossil fuels is accumulating dangerous levels of greenhouse gases in the atmosphere and thereby is causing global warming. Growing public concerns over global warming (as the greenhouse gas emissions increases by use of fossil fuel) has encouraged to study cleaner energy options, like PV, biomass, wind, and micro hydro systems for several applications. As the world wakes up to the reality of climate change, electricity will increasingly have to come from renewable sources such as wind and solar. Demand of electricity is expected to increase 8-10% every year by 2030. Pakistan is in a good position for harvesting renewable energy sources because it has abundant wind and sun. Renewable energy resources like solar and wind offer clean and economically competitive. For meeting the energy demand, PV-wind hybrid power generating systems can be beneficial in enhancing the economic and environmental sustainability of renewable energy systems.
The basic method for this project is the combined power generating system by wind turbine and solar energy panel. A hybrid arrangement of combining the power harnessed from both the wind and the sun and stored in a battery can be a much more reliable and realistic power source. Using this system power generation by wind turbine when wind source is available and generation from solar panel when sun light radiation is available can be achieved. Both units can generate power when both sources are available. The load can still be powered using the stored energy in the batteries even when there is no sun or wind.
Project ObjectivesOur aim is to increase the overall efficiency of the system above 90% with lowest possible cost. To increase the life of system to ensure that the system will run for many years without failure additional feature such as overload protection, short circuit, thermal overload, over charge (for battery) will be added to ensure safe operation with maximum reliability for the system.
Project Implementation MethodIntermittent energy resources and energy resources unbalance are the most important reason to install a hybrid energy supply system. The Solar PV wind hybrid system suits to conditions where sunlight and wind has seasonal shifts. As the wind does not blow throughout the day and the sun does not shine for the entire day, using a single source will not be a suitable choice. A hybrid arrangement of combining the power harnessed from both the wind and the sun and stored in a battery can be a much more reliable and realistic power source. The load can still be powered using the stored energy in the batteries even when there is no sun or wind. Hybrid systems are usually built for design of systems with lowest possible cost and also with maximum reliability. The high cost of solar PV cells makes it less competent for larger capacity designs. This is where the wind turbine comes into the picture, the main feature being its cheap cost as compared to the PV cells. Battery system is needed to store solar and wind energy produced during the
day time. During night time, the presence of wind is an added advantage, which increases the reliability of the system.In the monsoon seasons, the effect of sun is less at the site and thus it is apt to use a hybrid wind solar system.
Very high reliability (combines wind power, and solar power) 1) Long term Sustainability 2) High energy output (since both are complimentary to each other) 3) Cost saving (only one time investment) 4) Low maintenance cost (there is nothing to replace) 5) Long term warranty 5) No pollution 6) Clean and pure energy 7) Provides un-interrupted power supply to the equipment 8) The system gives quality power out-put DC to charge directly the storage battery or provide AC. 9) The system can be designed for both off-grid and on grid applications. 10) Efficient and easy installation, longer life
Technical Details of Final DeliverableSolar-Wind hybrid Power system is the combined power generating system by wind mill and solar energy panel.
It also includes a battery which is used to store the energy generated from both the sources. Using this system power
generation by windmill when wind source is available and generation from PV module when light radiation is available
can be achieved. Both units can be generated power when both sources are available. By providing the battery
uninterrupted power supply is possible when both sources are idle.. The power generated from wind
mill is of AC voltage which is converted through AC-DC rectifier. A special type of converter is used to step up or stepdown through MOSFET switching called “SEPIC” converter for wind mill. For solar system cuk converter is used for the regulation. The micro controller incorporated in this scheme, which regularly refers the operation of sources and switches the corresponding converters and fed into change the battery or to the load through inverters. The output of the inverter is connected with the load and after that the voltage is stepped up by a transformer. The driver circuit is used to give the gate signal for the MOSFET of converters.
