The present invention relates to renewable hybrid power generation system. More specifically the present invention relates to hybrid power generation system which utilizes wind energy and solar energy in order to generate electric power. The present system can be easily installed at rural areas and highways.

BACKGROUND OF THE INVENTION
This section is intended to provide information relating to the field and background of the invention and thus any approach/functionality described below should not be assumed to be qualified as prior art merely by its inclusion in this section.
With over 1.3 billion population, 29 states and 7 union territories comprises a developing nation with a potential to change the course of future is India. With its ever changing growth the country strives for its need to be fulfilled but fails to achieve it due to its vast population. When it comes to electricity India is considered to be the 4th largest consumer in the entire world and suffers due to its lack of availability. India's electricity sector is dominated by fossil fuels, and in particular coal, which is about three fourths of all electricity. This way of producing electricity is still not able to suffice the need of people. With over 600 million people especially in rural areas are suffering from the shortage of electricity. In addition to this India has surplus energy generation capacity but lacks adequate infrastructure for its production efficiently.
In this 21st century there are more methods to produce energy. Some of them are eco-friendly and some of them cause pollution. In order to produce energy by eco-friendly means, the best idea is by using renewable energy. The use of non-renewable resource is also a factor to be considered when it comes to environment. India is the third largest emitter of greenhouse gases. If India's emission of greenhouse gas continue to rise by 2040 it will overtake the United States as the world's second-highest emitter, behind only china, according to estimates by the International Energy Agency. Total carbon dioxide emission for India was 1.8 tons per capita in 2017 which is increasing yearly at an alarming rate.
The shortage of electricity is a problem that can be solved when more infrastructure are to be built but then they will create more emission of greenhouse gases as to produce electricity one must use non-renewable resource. So a new way Is required to solve the power shortage problem and also to not harm environment. This can only be done by the use of renewable resources for producing electricity. Renewable resources are the way through which the problem of energy shortage and environment harm can be solved. In can play a supporting role to power generation and will prove to suffice the need to people who are not able to receive electricity. Renewable resources are like wind energy, solar energy, hydro energy, pressure energy, biomass energy etc. India is slowly taking its steps in the direction of utilizing more renewable resources.
The utilization of renewable resource is very much needed, but when there is utilization of multiple renewable resources all at the same time and that also from the same system will prove to be more efficient and convenient. This is done with the help of hybrid power generation machine. This machine is capable to utilize renewable resources like wind energy and photovoltaic energy. This system best utilization can be done on highway roads where wind energy from vehicles can be recaptured with the help of wind turbines when it is placed on medians so that it can capture wind from both sides.
Wind is generated from solar energy by uneven heating of the earth. This uneven heating creates pressure difference in the atmosphere, generating wind. This wind can then be harnessed by a wind turbine. As the wind pushes the blades of a turbine, a generator attached to the axis of the shaft and when spun creates electricity that can be sent to the grid and used in households for electricity. A major hindrance in the growth of wind energy is fluctuation in the sources of wind. Thus highway should appear to be a sufficient source of potential wind energy. Each vehicle on the highway offers an intermittent and uncontrolled source of wind power. The design of the wind turbine must include storage of power and a system to distribute the generated power effectively.
In renewable energy field sector the wind turbine plays an important role in energy production. The current attempt deals with use of vertical axis wind turbine to generate the electricity as form of energy with some attachments. The main principle of vertical axis wind turbine is to convert kinetic energy of flowing wind into mechanical energy of rotation of blade or shaft. The flowing wind imparts force on turbine blades in the direction of wind flow. This force depends upon the wind speed, more the wind speed more is the force of impact. This force generates couple on the turbine. Once, this couple overcomes mechanical resistance of turbine, the turbine starts rotating. This rotation of turbine can be utilized for generation of electricity by connecting generator to shaft of turbine.
Second usage of renewable resource is the photovoltaic energy i.e. solar energy. Solar energy is considered till today the greatest and the most eco-friendly way to generate electricity. It basically uses solar panels i.e. photovoltaic module that is a packaged, connected assembly of typically 6*10 photovoltaic solar cells. Photovoltaic module consists of photovoltaic array that generates and supplies electricity.
In general, the street lamps that are generally used to turn on the street lamp using electric energy, and other street lamps using alternative energy and solar light are being used in small scale. Street lamps that use electrical energy are not only economically expensive for plumbing and wiring when people want to use them in rare places, but can replace street lamps that use electrical energy in view of the depleted energy sources on the planet. The spread of environment-friendly street lights is required.
A solar cell is a solid-state electrical device (p-n junction) that converts energy of light directly into electricity using photovoltaic effect. The process of conversion first requires material like silicon which absorbs the solar energy, then raises an electron to a higher energy state and then the flow of this high energy electron to an external circuit. The amount of current generated by photon excitation in a PV cell at given temperature is affected by intensity and wavelength of incident rays. So it is required to control the process of solar energy conversion effectively. The materials used in PV cells have different spectral response to incident light, and exhibit a varying sensitivity with respect to the absorption of photons at given wavelength. Each semiconductor material will have an incident radiation threshold frequency, below which no electron will be subjected to photovoltaic effect. Above the threshold frequency, kinetic energy of the emitted photoelectron varies according to the wavelength of the incident variation but has no relation to the light intensity. Increasing the light intensity will proportionally increase the rate of photoelectron emission in the photovoltaic material.
Solar Energy Conversion System or Solar photovoltaic (PV) systems, as a mature technology with life expectancy of 20– 30 years, are semiconductor devices that convert sunlight into DC electricity through the transfer of electrons. The process of energy conversion mainly occurs in two stages; generation of electron-hole pair through the absorption of light in semiconductor material and afterwards, separation of electron to the negative terminal and hole to the positive terminal by the structure of the device to supply electricity. In order to serve the purpose of producing a greater amount of electrical energy, solar cells may be arranged in series and multiple modules are linked together to build an array. Solar-PV systems offer several advantages including simple design, long operation life, high reliability and not producing any further pollution during energy provision.
In actual applications, the light absorbed by solar cells will be a combination of direct solar radiation as well as diffuse light bounced off the surrounding surfaces. Solar cells are usually coated with anti-reflective material so they absorb the maximum amount of radiation possible. The PV cells can be arranged in a series configuration to form a module, and module can then be connected in parallel series configuration to form arrays. When connecting the cells or module in series, they must have the same current rating to produce an additive voltage output and similarly, modules must have the same voltage rating when connected in parallel to produce large current output.
All the energies i.e. wind energy, solar energy, piezoelectric energy combine into a single system will be used to produce a significant power than a system consisting of only one of these energies. The obstacle that is faced in producing such a system is in achieving a design that can inherit the current situation of the present road construction with minimal change on it. By producing a vertical blade turbine with solar panels at its crest should be of proper size that can be installed on the highway medians and should be place at proper place so that it can utilize both natural breeze as well as the wind created due to passing vehicles.
Operational noise level is other design considerations. The wind turbines should have as little negative impact on the placement location as possible. Wind turbines are traditionally used in remote locations. This offers the additional challenge of having to transport the power generated to the location wherein it will be utilized. Other consideration that needs to be taken care of is the price of entire system. The cost of system, calculated in energy savings must be recovered in a reasonable time period.
Hybrid street light, developed in response to these demands, is a nature-friendly lighting system that converts the natural energy of wind and sunlight into electrical energy and stores it in a battery, which is used for night lighting. There is an advantage that can develop only by wind.
