The document summarizes a seminar presentation on utilizing hybrid PV-wind energy systems. It discusses how hybrid systems combine solar and wind power to provide reliable energy. It describes the components of a hybrid system, including PV panels, wind turbines, batteries, inverters, and controllers. The document outlines the advantages of hybrid systems in providing sustainable energy without pollution for powering homes, villages and other remote locations off the main grid. It concludes that the combination of solar and wind resources performs better than either technology alone due to their complementary seasonal profiles.

2. INTRODUCTION
• Since the oil crisis in the early 1970’s, utilization
of solar and wind power has become increasingly
significant, attractive and cost-effective. In
recent years, hybrid PV/Wind system (HPWS)
has become alternatives to meet environmental
protection requirement and electricity demands.
With the complementary characteristics
between solar and wind energy resources for
certain locations, hybrid PV/Wind system with
Storage banks presents an unbeatable option for
the supply of small electrical loads at remote
locations where no utility grid power supply and
It's also pollution less.

3. WHAT IS A HYBRID POWER SYSTEM
Hybrid systems, as the name implies, combine two or more modes of
electricity generation together, usually using renewable technologies
such as solar photovoltaic (PV) and wind turbines. Hybrid systems
provide a high level of energy security through the mix of generation
methods, and often will incorporate a storage system (battery, fuel cell)
or small fossil fuelled generator to ensure maximum supply reliability
and security.
There are different types of Hybrid power systems :-
 Solar wind hybrid power plant.
 Wave, wind & solar hybrid power plant.
 Wind turbine with battery storage and diesel backup
generator.
** only discuss about solar & wind hybrid power plant.

4. SOLAR ENERGY
 Four-fifths of the sun’s energy falls on the
oceans and drives the water cycle. Evaporation
from the sea causes rain to fall on the land,
resulting in the global hydropower resource.
The remaining fifth of the sun’s energy falls on
the land.
 Sun rays converted into electrical energy by
Using PV (photovoltaic cell).
 Unlimited supply
 No negative impact
 Free of cost
 Free from pollution

5. SOLAR ENERGY
(DISADVANTAGES)
Apart from its advantages few Disadvantages are as follows:-
 Solar power is not always completely predictable because it depends
on the amount of sunlight that reaches the Earth at any given time.
This precludes solar power generation during the night when
sunlight does not reach the part of the Earth in which the cell is
located and limits solar power generation when cloud cover scatters
portions of the electromagnetic spectrum.
 Some forms of solar power are not currently cost competitive. A
Photovoltaic power station is expensive to build, about 10% efficient,
and the energy payback time is large of the order of five years.

6. WIND ENERGY
 The uneven heating of the earth’s surface by
the sun causes wind. This heat is absorbed by the
ground or water and is then transferred into
the air, causing differences in air temperature,
density and pressure. These differences then create
forces that push the air around. Like the
water that flows in the river.
 The wind contains energy that can be converted
into electricity using wind turbines. Currently,
more than 20,000 wind turbines are used for
generating electricity around the world.
 No fuel cost
 Free from pollution

7. WIND ENERGY
(DISADVANTAGES)
As Solar Energy Wind Energy too has some Disadvantages :-
 Wind power is irregular in many locations, because consistent wind
is needed to ensure continuous power generation
 Commercial generation requires a wind farm over large areas
having an effect on scenery
 Thus to overcome from the disadvantages of these energy techniques we
should combine these two techniques and By this we can achieve more
efficient and environment friendly energy source throughout year.

8. HYBRID PV & WIND POWER SYSTEM
(HPWS)WORKING :-
 Solar & Wind turbine produced DC
power
 Inverter convert DC to AC
 Controller monitor’s the system
The System components:-
 PV Panels
 Wind Turbine & Aero-Wind Generator
 MPPT (Maximum power point
tracking) Controller
 Battery Bank
 Inverter
 Loads

9. DESCRIPTION OF COMPONENTS :-
PV Panels:-
A number of PV panels connected in series
and/or in parallel giving a DC output
Wind Turbine & Aero-Wind Generator :-
Which is installed on top of a tall tower,
collects kinetic energy from the wind. An electric
generator is coupled to the propeller shaft
directly, this propeller in turn rotates rotor of
the electric generator and in turn generates
DC electricity. The output from the wind
generator varies as per the wind speed.

10. MPPT (Maximum power point tracking) Controller:-
•Controller compares voltages of PV panel & Battery
•Figure out best voltage to charge Battery
Battery bank:-
to Stored the energy
Inverter:-
Converts stored DC power to AC
Loads:-
Stands for the network connected
appliances in the building that are fed
from the inverter (AC loads), or from
the battery bank(DC loads).

11. ADVANTAGES
 Very high reliability (combines wind power, and solar power)
 Long term Sustainability
 High energy output (since both are complimentary to each other)
 Cost saving (only one time investment)
 Low maintenance cost (there is nothing to replace)
 No pollution
 The system can be designed for both off-grid and on grid
applications. ( Discuss only about the off-grid applications).

13. CONCLUSION
 Because the seasonal profiles of the wind and solar
resources are somewhat complementary in some reason,
combination of wind and solar perform better than either
wind or solar alone .
 Under the circumstance of power failure this hybrid
system keeps the continuity of supply without producing
any pollution .
 High Efficiency than Individual systems.
