Abstract: Reaching the non-electrified rural population is currently not possible through the extension of the grid, since the connection is neither economically feasible, nor encouraged by the main actors. Further, the increases in oil prices and the unbearable impacts of this energy source on the users and on the environment, are slowly removing conventional energy solutions, such as fuel genets-based systems, from the rural development agendas. This problem can overcome by using “Hybrid Power Generation Using Solar and Wind Energy”. Hybrid systems have proved to be the best option to deliver “high quality” power. With increasing concern of global warming and the depletion of fossil fuel reserves, many are looking at sustainable energy solutions to preserve the earth for the future generations. Other than hydro power, wind and photovoltaic energy holds the most potential to meet our energy demands. Alone, wind energy can supply large amounts of power but its presence is highly unpredictable as it can be here one moment and gone in another. Similarly, solar energy is present throughout the day, but the solar irradiation levels vary due to sun intensity and unpredictable shadows cast by clouds, birds, trees, etc. The common inherent drawback of wind and photovoltaic systems are their intermittent natures that make them unreliable. However, by combining these two intermittent sources and by incorporating maximum power point tracking (MPPT) algorithms, the systems power transfer efficiency and reliability can be improved significantly.

Description of Prior Art
The use of wind turbines to generate electricity is well known in the prior art. These turbines generally include a vertical tower which supports a turbine operatively connected to a propeller which spins on a horizontal axis or to another device designed to take advantage of the moving wind. Many alternative designs and orientations have been shown and discussed in the prior art.
Generating electricity from renewable energy sources has received a great deal of attention in the past few years. Yet both wind and solar power generation have significant disadvantages. For example, wind speed and direction vary, making the amount of electricity generated by a wind turbine inconsistent and clouds obscure the sun making the amount of power generated by solar panels also inconsistent. To address these inconsistencies, it is desirable to exploit both solar and wind energy together for power generation for economic, practical, and environmental reasons.

Detailed description of the invention
With the unavoidable shortage of fossil fuel sources in the future, renewable types of energy have become a topic of interest for researchers, technicians, investors, and decision makers all around the world. New types of energy that are getting attention include hydroelectricity, bioenergy, solar, wind and geothermal energy, tidal power, and wave power. Because of their renewability, they are considered as favorable replacements for fossil fuel sources.
Renewable energy sources are currently one of the most, if not the only, suitable option to supply electricity in fragmented areas or at certain distances from the grid. Indeed, renewable are already contributing to the realization of important economic, environmental and social objectives by the enhancement of security of energy supply, the reduction of greenhouse gases and other pollutants and by the creation of local employment which leads to the improvement of general social welfare and living conditions.
In the recent times, to avoid pollution and to conserve non-renewable energy resources like coal, petroleum, etc., renewable energy sources like solar, wind, etc., are being preferred for power generation. The combination of renewable energy sources can also be used for generating power called as hybrid power system.Aiming for the purpose of maximum power generation, As we know solar and wind energy are now-a-days used even at homes as an extra hand for power consumption and in some places panels are installed above the street lights such that the power generated by the panel is used for the working of street light individually, this in short scenario may look as an small amount but in an long run of power consumption this may be a part of decreasing load on the grid so if we manage to produce the maximum solar energy through the panels already installed (or) panels that are going to be installed, all the time during the day this may be a solution to power shortage problem in many cases as we can also send the extra power which could not be stored by the batteries to the grid, this may also be helpful not up to a large extent but could be utilized to manage the demand when marked up to a higher scale .
The hybrid energy subsystem preferably comprising of a power combination system, a control system, and a power output system is preferred. This combination process includes power converters and inverters and charge controllers considered standard with wind turbine power production and solar PV power production capabilities. The difference will be the combining network to add these two power generation capabilities outputs together to one hybrid, yet integrated power source.
Sun & wind normally complement each other with sun energy being available for the period when wind energy is comparatively low and vice-versa. Thus the combination of sun and wind provided an ideal solution. The power plant has 6.6 kW power generation from wind energy and 3.4 kW power generation from solar. The power so generated is being supplied to 24 houses of villages for two lights, one fan and six street lights.
The hybrid power plant has been generating 12 units of electricity per day on an average basis and sometimes when the wind velocity is high, the power generated is about 30 units per day. The average cost of generation power in this mode comes out to be about Rs. 15/-per unit. The plant has generated about 2865 units of electricity in one year. The villagers are contributing Rs.50/- per month towards energy charges and are enjoying 24x7 electricity. The power availability in these villages has increased from about 50% to 100%. i.e; form 7-12 hours in the pre project scenario to 24 hours in the post project period.
The electrical energy produced by the system needs to be either utilized completely or stored. Complete utilization of all the energy produced by the system for all the time is not possible. So, it should be store rather than useless wasting it. Electrical batteries are the most relevant, low cost, maximum efficient storage of electrical energy in the form of chemical reaction. Hence, batteries are preferred. The energy generated from the proposed project is need to be store. So, two batteries are needed. One is attached to wind turbine for which a 120AmpH battery will be required, which will be fair enough full fill the storage capacity for targeted value. The second battery is 80AmpH is preferred for storing solar energy. But, as per application/ storage and demand battery capacity can be variable.
This invention consists of solar panels and vertical axis wind turbine, are connected to charge controllers then the output of charge controller is connected to solar controller to synchronize the solar and wind voltage, the synchronized dc voltage is given to battery and the batteries output is connected to inverter.

Detailed description of the drawing
From the figure 1, When the light rays of sun fall on the solar panel the panel starts producing the electrical energy and the wind turbine also generates electrical energy, the both energies are at different frequencies so that the bridge rectifier is used to maintain constant dc volage. The rectified dc voltages are synchronized by solar controller and given to battery to store and the stored dc voltage is given to inverter to convert the dc to ac voltage, the output of the inverter voltage is given to ac loads.
Figure 1 shows, a solar panel is a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A photovoltaic module is a packaged, connected assembly of solar cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring. Photovoltaic cells or panels are only one way of generating electricity from solar energy. They are not the most efficient, but they are the most convents to use on a small to medium scale. PV cells are made of silicon, like that used in computer "chips". While silicon itself is a very abundant mineral, the manufacture of solar cells (as with computer chips) must be in a very clean environment. This causes production costs to be high. A PV cell is constructed from two types of silicon, which when hit by solar energy, produce a voltage difference across them, and, if connected to an electrical circuit, a current will flow. A few photovoltaic cells will be connected in a "Module", and usually encapsulated in glass held a frame which can then be mounted as required. The cells in a module will be wired in series or parallel to produce a specified voltage. What may be referred to as a 12- volt panel may produce around 16 volts in full sun to charge to 12-volt battery.
In figure 1, Wind turbine can be defined as a fan consisting of 3 blades that rotate due to blowing wind such that the axis of rotation must be aligned with the direction of blowing wind. A gear box is used for converting energy from one device to another device using mechanical method; hence, it is termed as a high-precision mechanical system. There are different types of wind turbines, but the frequently used wind turbines are horizontal axis turbines and vertical axis turbines. The figure shows different blocks of the wind turbine generator system. An electrical generator is coupled with wind turbine; hence, it is named as wind turbine generator. There are different types of wind turbine generators and these wind turbine generators can be directly connected to the power grid or loads or batteries based on different criteria.
An inverter is a motor control that adjusts the speed of an AC induction motor. It does this by varying the frequency of the AC power to the motor. An inverter also adjusts the voltage to the motor. This process takes place by using some intricate electronic circuitry that controls six separate power devices. They switch on and off to produce a simulated three phase AC voltage. This switching process is also called inverting DC bus voltage and current into the AC waveforms that are applied to the motor. This led to the name inverter. For the rest of this discussion, the term inverter will be used in place of adjustable speed drive. Most inverters are of the variable voltage, variable frequency design. They consist of a converter section, a bus capacitor section, and an inverting section. The converter section uses semiconductor devices to rectify (convert) the incoming fixed voltage, fixed frequency 3-phase AC power to DC voltage which is stored in the bus capacitor bank. There it becomes a steady source of current for the power devices which are in what is known as the inverting section. The inverting section absorbs power from the DC bus cap bank, inverts it back to simulated 3-Phase AC sinewaves of varying voltage and varying frequency that are typically used to vary the speed of a 3-phase induction motor.
A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged. Not always, but usually. Generally, there is no need for a charge controller with the small maintenance, ortrickle charge panels, such as the 1 to 5-watt panels. A rough rule is that if the panel puts out about 2 watts or less for each 50-battery amp-hours, then you do not need one. Charge controls come in all shapes, sizes, features, and price ranges. They range from the small 4.5-amp (SunGard) control, up tothe 60-to-80-amp MPPT programmable controllers with computer interface. Often, if currents over 60 amps are required, two or more 40-to-80-amp units are wired in parallel. The most common controls used for all battery-based systems are in the 4-to-60-amp range, but some of the new MPPT controlssuch as the Outback Power Flomax go up to 80 amps.
Electrical batteries are the most relevant, low cost, maximum efficient storage of electrical energy in the form of chemical reaction. Hence, batteries are preferred. The energy generated from the proposed project is need to be store. So, two batteries are needed. One is attached to wind turbine for which a 120AmpH battery will be required, which will be fair enough full fill the storage capacity for targeted value. The second battery is 80AmpH is preferred for storing solar energy. But, as per application/ storage and demand battery capacity can be variable.
