Hybrid renewable energy source is becoming popular because it is composed of two or more energy sources. This combination of two energy sources is an efficient way of generating energy. Hybrid energy systems are used in remote areas for power generation. The use of hybrid power generations came forward due to the high prices of oil. The use of hybrid energy systems can optimize the power supply especially in rural areas. However it is still considered expensive and difficult to combine two or three energy sources together, but it is a one time expense. This one time expense can be of many uses to people living in remote areas
Examples of Hybrid Energy
Hybrid energy is a combination of two or more energy sources for producing electricity. There are many sources of combining renewable energy sources to produce power but two of them are biomass wind fuel cell and photovoltaic wind. The first hybrid energy sources biomass wind fuel cell is a combination of 60% biomass and 20% wind power along with the derivation of energy from fuel cells. The hybrid energy sources can help farmers to run their tube wells to provide water to their irrigation land. Combining two or three energy sources to form one source is capable of generating efficient energy to power a house or a small industrial unit. The photovoltaic wind power is the combination of solar cells and wind turbines to generate electricity. The energy by wind turbines and solar panels is combined in a battery bank. It is then transformed to the inverter and then it helps in generating alternate current. The hybrid energy sources are much more cost effective and environment friendly.
Uses of Hybrid Energy
Hybrid energy sources can be used to generate electricity which can power many applications like TV, water pumps, grinders, irons and other machinery. Hybrid energy can also be used for supplying electricity to schools and churches which are located in remote areas. It can help the users to run electrical appliances as well as outdoor and indoor lights. These power systems can supply direct current and alternate current accordingly. The hybrid energy is useful only if we do not overlook the important considerations before deploying this energy. The input and output parameters should be compatible to each other. Also analyze the variations in the two very different energy sources like wind energy and solar power. The reduced range of power supply and the variation in the energy capabilities of both power plants should be monitored using charge controller. It is imperative to use power inverters to transform electric current into usable form like alternate current.
Components of Hybrid Power Systems
There are few basic hybrid systems without which the working of the hybrid systems is not possible. For example if want to generate electricity by combining photovoltaic andwind power we must possess an array of solar panels, wind generators, a backup storage and battery system and a power converter. The photovoltaic panels or PV generators is a combination of series of solar panels. These solar panels are in turn made up of solar cells. An array of solar panels alone is considered an important and powerful energy sources. The wind generator converts the energy of the wind (kinetic energy) into mechanical energy. The energy generated from both sources is combined into one battery inverter or storage unit. This storage unit conserves the energy generated form the solar panels and wind turbines. This energy is then converted to usable energy by using inverter. Just like solar and wind power plants the hybrid power plants can also be off grid and on grid therefore increasing the diversity of this energy technology.
