This hybrid solar-wind power generating system is suitable for industries and also domestic areas. Keywords: Solar energy, Wind energy, Renewable energy, PV cell, Hybrid power system I. INTRODUCTION We all know that the world is facing a major threat of fast depletion of the fossil fuel reserves. Most of the present energy demand is met by fossil and nuclear power plants. A small part is met by renewable energy technologies such as the wind, solar, biomass, geothermal etc. There will soon be a time when we will face a severe fuel shortage.

As per the law of conservation of energy, Energy can neither be created, nor be destroyed, but it can only be converted from one form to another. Most of the research now is about how to conserve the energy and how to utilize the energy in a better way. Research has also been into the development of reliable and robust systems to harness energy from nonconventional energy resources. Among them, the wind and solar power sources have experienced a remarkably rapid growth in the past 10 years. Both are pollution free sources of abundant power. With high economic growth rates and over 17 percent of the world s population, India is a significant consumer of energy resources.

Despite the global financial crisis, India s energy demand continues to rise. India consumes its maximum energy in Residential, commercial and agricultural purposes in comparison to China, Japan, and Russia.1 Solar energy is energy from the Sun. It is renewable, inexhaustible and environmental pollution free. Solar charged battery systems provide power supply for complete 24 hours a day irrespective of bad weather.

By adopting the appropriate technology for the concerned geographical location, we can extract a large amount of power from solar radiations. More over solar energy is expected to be the most promising alternate source of energy. The global search and the rise in the cost of conventional fossil fuel is making supply-demand of electricity product almost impossible especially in some remote areas. Generators which are often used as an alternative to conventional power supply systems are known to be run only during certain hours of the day, and the cost of fueling them is increasingly becoming difficult if they are to be used for commercial purposes. Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing, grinding grain and for irrigation.

Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been in use since ancient times and at the beginning of the 20th century it is being used to generate electric power.

Windmills for water pumping have been installed in many countries particularly in the rural areas. Wind turbines transform the energy in the wind into mechanical power, which can then be used directly for grinding etc. Or further converting to electric power to generate electricity. Wind turbines can be used singly or in clusters called wind farms.

Copyright to IJAREEIE 2 There is a growing awareness that renewable energy such as photovoltaic system and Wind power have an important role to play in order to save the situation. Hybrid power system consist of a combination of renewable energy source such as wind generators, solar etc of charge batteries and provide power to meet the energy demand, considering the local geography and other details of the place of installation.

These types of systems are not connected to the main utility grid. They are also used in stand-alone applications and operate independently and reliably. The best application for these type of systems are in remote places, such as rural villages, in telecommunications etc. The importance of hybrid systems has grown as they appear to be the right solution for a clean and distributed energy production.1 This paper presents the Solar-Wind hybrid Power system that harnesses the renewable energies in Sun and Wind to generate and supply electricity to a private house, farm house, a small company, an educational institution or an apartment house depending on the need at the site where used. SOLAR WIND HYBRID ENERGY SYSTEM Fig.1. Block Diagram Solar-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.

Shows the functional block diagram of hybrid wind solar energy system. 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 step down 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. III.IMPLEMENTATION OF HYBRID ENERGY SYSTEM Intermittent 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.2 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 Copyright to IJAREEIE 3 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.

The system components are as follows. 1.Photovoltaic solar power Solar panels are the medium to convert solar energy into the electrical energy. Solar panels can convert the energy directly or heat the water with the induced energy. PV (Photo-voltaic) cells are made up from semiconductor structures as in the computer technologies. Sun rays are absorbed with this material and electrons are emitted from the atoms.this release activates a current. Photovoltaic is known as the process between radiation absorbed and the electricity induced. Solar power is converted into the electric power by a common principle called photo electric effect.

The solar cell array or panel consists of an appropriate number of solar cell modules connected in series or parallel based on the required current and voltage. Wind Power The wind energy is a renewable source of energy. Wind turbines are used to convert the wind power into electric power. Electric generator inside the turbine converts the mechanical power into the electric power. Wind turbine systems are available ranging from 50W to 3-4 MW. The energy production by wind turbines depends on the wind velocity acting on the turbine. Wind power is able to feed both energy production and demand in the rural areas.

It is used to run a windmill which in turn drives a wind generator or wind turbine to produce electricity.3 3. Batteries The batteries in the system provide to store the electricity that is generated from the wind or the solar power. Any required capacity can be obtained by serial or parallel connections of the batteries. The battery that provides the most advantageous operation in the solar and wind power systems are maintenance free dry type and utilizes the special electrolytes. These batteries provide a perfect performance for long discharges.4 4. Inverter Energy stored in the battery is drawn by electricals loads through the inverter, which converts DC power into AC power. The inverter has in-built protection for Short-Circuit, Reverse Polarity, Low Battery Voltage and Over Load.

Microcontroller The microcontroller compares the input of both Power system and gives the signal to the particular relay and charges the DC Battery. The DC voltage is converted into AC Supply by Inverter Circuit. The MOSFET (IRF 540) is connected to the Secondary of the centre tapped transformer. By triggering of MOSFET alternatively, the current flow in the Primary winding is also alternative in nature and we get the AC supply in the primary winding of the transformer. Copyright to IJAREEIE 4 Fig.2.Hybrid energy system Depending on the environmental conditions, required energy for the system can be supplied either separately from the wind or solar systems or using these two resources at the same time is shown in Fig. IV.EXPERIMENTAL SETUP The hardware of Solar PV Wind hybrid energy system is implemented and the output is fed to the load is shown in fig.3.

V.CONCLUSION In the present work a Solar PV Wind Hybrid Energy System was implemented. A portion of the energy requirement for a private house, farm house, a small company, an educational institution or an apartment house depending on the need at the site where used has been supplied with the electricity generated from the wind and solar power. It reduces the dependence on one single source and has increased the reliability.

Hence we could improve the efficiency of the system as compared with their individual mode of generation. REFERENCES 1 Arjun A. K., Athul S., Mohamed Ayub, Neethu Ramesh, and Anith Krishnan, Micro-Hybrid Power Systems A Feasibility Study, Journal of Clean Energy Technologies, Vol.

Contents. Wind-hydro system A wind-hydro system generates combining wind turbines and. The combination has been the subject of long-term discussion, and an experimental plant, which also tested wind turbines, was implemented by at its hydro electric power site in the late 1970s, but was decommissioned within ten years. Since, no other system has been implemented at a single location as of late 2010.

Wind-hydro stations dedicate all, or a significant portion, of their wind power resources to pumping water into pumped storage reservoirs. These reservoirs are an implementation of. Advantages Wind and its generation potential is inherently variable.

However, when this energy source is used to pump water into reservoirs at an elevation (the principle behind pumped storage), the potential energy of the water is relatively stable and can be used to generate electrical power by releasing it into a plant when needed. The combination has been described as particularly suited to islands that are not connected to larger grids. Proposals During the 1980s, an installation was proposed in the Netherlands. The would be used as the reservoir, with wind turbines located on its dike. Feasibility studies have been conducted for installations on the island of and on the. An installation at, Greece, had entered the construction phase as of 2010. The island of is where the first world's first wind-hydro power station is expected to be complete.

Hybrid Solar Wind Power System

Called this 'a blueprint for a sustainable future on planet Earth'. It was designed to cover between 80-100% of the island's power and was set to be operational in 2012. However, these expectations were not realized in practice, probably due to inadequate reservoir volume and persistent problems with grid stability. 100% renewable energy systems require an over-capacity of wind or solar power. Wind-hydrogen system. One method of storing wind energy is the through the of.

This is subsequently used to generate electricity during periods when demand can not be matched by wind alone. The energy in the can be converted into electrical power through technology or a linked to an.

Successfully has many issues which need to be overcome, such as of the materials used in the power system. This technology is being developed in many countries and has even seen a recent of an Australian firm called Wind Hydrogen that looks to commercialise this technology in both Australia and the UK. Essentially Wind Hydrogen offers a source of domestic and vehicular energy for rural communities where current costs are prohibitive.

Wind Diesel system on in Canada A wind-diesel hybrid power system combines and wind turbines, usually alongside ancillary equipment such as energy storage, power converters, and various control components, to generate electricity. They are designed to increase capacity and reduce the cost and environmental impact of electrical generation in remote communities and facilities that are not linked to a. Wind-diesel hybrid systems reduce reliance on diesel fuel, which creates pollution and is costly to transport. History Wind-diesel generating systems have been under development and trialled in a number of locations during the latter part of the 20th century. A growing number of viable sites have been developed with increased reliability and minimized technical support costs in remote communities.

Technology The successful integration of wind energy with diesel generating sets relies on complex controls to ensure correct sharing of intermittent wind energy and controllable diesel generation to meet the demand of the usually variable load. The common measure of performance for wind diesel systems is Wind Penetration which is the ratio between Wind Power and Total Power delivered, e.g. 60% wind penetration implies that 60% of the system power comes from the wind. Wind Penetration figures can be either peak or long term.

Sites such as, Antarctica, as well as and in Australia have peak wind penetrations of around 90%. Technical solutions to the varying wind output include controlling wind output using variable speed wind turbines (e.g., ), controlling demand such as the heating load (e.g.

Mawson), (e.g. Powercorp, Coral Bay). Some installations are now being converted to systems such as on in Canada which is due for completion in 2010.
