Hybrid wind solar energy system

  1. 1. GUIDED BY PRESENTED BYMr. V. Chaitanya Prasad (M-Tech) K. Hari KishoreAsst.Prof.
  2. 2. AbstractThis project presents a new system configuration of the front-end rectifier stage for a hybrid wind/solar energy system.This configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources.
  3. 3. In Search of Environmental friendly& Sustainable energy sourcesEnvironmentally friendly solutions are becoming more prominent than ever as a result of concern regarding the state of our deteriorating planet.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.
  4. 4. Introduction to Solar EnergySolar Energy was invented many years back with a piece of shiny metal which can reflect sunrays, it satisfied the basic need of cooking and heating in ancient days.In modern days it is being used in many ways by converting the solar energy to electrical energy with a Solar Panel
  5. 5. Working of Solar Panel
  6. 6. Disadvantages of Solar Energy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.This made the concept of solar energy an unreliable one and less used
  7. 7. Introduction to Wind EnergyWind is also a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun.Wind flow patterns are modified by the earth’s terrain, bodies of water and vegetation.Wind turbines are used to grab this wind to rotate themselves and thus convert the kinetic energy in the wind into mechanical and then to electrical by rotating alternators which are connected internally
  8. 8. Working of Wind Turbines
  9. 9. Disadvantages of Wind EnergyWind Energy is capable of supplying large amounts of power but its presence is highly unpredictable as it can be here one moment and gone in another.This made the concept of wind energy an unreliable one and less used
  10. 10. Introduction to Hybrid Wind-SolarEnergy System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 system’s power transfer efficiency and reliability can be improved significantly.
  11. 11. Block Diagram of Hybrid Wind-Solar Energy System
  12. 12. Maximum Power Point Tracking(MPPT)
  13. 13. AdvantageLow operating costEasy to chargeHigh power quality
  14. 14. ApplicationsDistributed Generation Applications,Constant Speed and Variable Speed Wind Energy Conversion Systems,Photovoltaic Energy System .
  15. 15. ConclusionBy combining the two intermittent sources of Wind and Solar and by incorporating maximum power point tracking (MPPT) algorithms, the system’s power transfer efficiency and reliability can be improved significantly.
