HYBRID POWER GENERATION BY SOLAR –WIND
INTRODUCTIONIt is possible that the world will face a global energy crisis
due to a decline in the availability of cheap oil andrecommendations to a decreasing dependency on fossil fuel.This has led to increasing interest in alternate power/fuelresearch such as fuel cell technology, hydrogen fuel, biodiesel,solar energy, geothermal energy, tidal energy and wind. Today,solar energy and wind energy have significantly alternated fossilfuel with big ecological problems.
RENEWABLE ENERGY Renewable
Available in wide spread
Free from pollution
Clean and pure energy
Solar Energy
Sun rays converted into electrical energy
Unlimited supply
No negative impact
Free of cost
Free from pollution
Wind Energy Converts wind energy into electrical energy
No fuel cost
Free from pollution
Geographical Region
Solar Average solar radiation 5kwh/sq m
2300-3200 sun shine hours available per year
Available most part of country
•Wind Southern and Western coastal areas are ideal location Annual average wind speed 5-6 m/s Attractive option to supplement the energy supply
HYBRID The thing made by combining two or more different element.
•Need of Hybridization
For increasing output For fulfilling demand of consumer Providing uninterrupted power supply System can design for both off grid and on grid
DIFFERENT HYBRID POWER TECHNOLOGY Solar-Wind Hybrid Power
Solar-Diesel Hybrid Power
Wind-Hydro Hybrid Power
Wind-Diesel Hybrid Power
Solar-Wind Hybrid Power
Ideal alternative in areas where wind velocity 5.6 m/s is available
Power clear and non polluting
Complement to each other
Stable power supply
COMPONENTS OF HYBRID GENERATOR Solar panel
Controller
Monitors the system starting and stopping engine as need
Why we use MPPT Charger Controller
•Consider solar panel Kyocera KC 130. It is rated at 7.39 𝐴𝑚𝑝𝑠 at 17.6
It’s power output is 130 Watts .
•Panel puts out 7.39 𝐴𝑚𝑝𝑠 & battery charges under 12V
• 7.39 𝐴𝑚𝑝𝑠 * 12V =88.8 Watts
• We lost over 41 Watts. But we paid for 130 Watts.
• To overcome this loss, we use MPPT Charger Controller.
Working of MPPT Charger Controller
•Controller compares voltages of PV panel & Battery
•Figure out best voltage to charge Battery
• Example: Controller takes 17.6 Volts at 7.4 𝐴𝑚𝑝𝑠 & gives output to10.8 𝐴𝑚𝑝𝑠 at 12Volts .
10.8 𝐴𝑚𝑝𝑠 * 12Volts = 129.6 Watts
• Now we still have almost 130 Watts.
Batteries
Stored the energy
Inverter
Converts stored DC power to AC
WORKING
Solar & Wind turbine produced DC power
Inverter convert DC to AC
Controller monitors the system
CHOICE OF COMPONENT Choice of components For 1000 Watt Load
Solar Panel: • Total load = 1000W •Period of operation or duration = 12 Hours •Then, Total Watt-Hour = 1000×12= 12000W-hr •The period of the solar panel exposed to the sun = 8 Hours (Averagely between 9am and 3pm) •Therefore solar panel wattage = 12000𝑊ℎ/8ℎ=1,500𝑊. •Hence solar panel of 1,500W will be needed for this design. •If solar panel of 150W is to be use the number of panels to arrange in parallel to achieve 1,500 Watt will be: No of panel =1500W/150𝑊=10 This shows 10 of 150 Watt solar panel will be required for this design
Charging Controllers:
For this design of 1000W solar power supply P=IV
Where
I is the expected charging current and
V is the voltage of the battery and V= 12 V
P is the power supply rating= 1000W
Hence I =𝑃/𝑣=1000/12=83𝐴𝑚𝑝𝑠.
Since the value 83.3 A Charging controllers is not readily available in the market then 1000A charging controller will be used.
Battery capacity:
Given that the total load P= 1000W and Operational period = 12 Hours
Watt-hour capacity = 12,000 W-hr To make the chosen battery to last long it is assumed that only a
quarter (¼) of the battery capacity will be made used of so that it will not be over discharged therefore hence the required batter capacity will be
12, 000 × 4 = 48,000 W-hr Now the choice of battery hour depends on A-H rating of the
storage battery. For example 1500AH, 12V batteries the number of batteries that
will be needed is 48000/1500 = 32 batteries. Hence, for this design , 1500AH 12V battery should be used, Therefore the total number of storage battery required for 1000W solar power supply system = 32
Inverter
Since the total load is 1000W it is advisable to size the required inverter to be 1500W as designed for solar panel ratings. Hence 1500W pure sign wave inverter is recommended in other to prolong the lifespan of the inverter.
APPLICATION Hotels
Business (Institutions and Government)
Large Estate Houses
Factories and manufacturing facilities
Commercial Power generation
Street lighting
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) Long term warranty No pollution Clean and pure energy Provides un-interrupted power supply to the equipment The system gives quality power out-put DC to charge
directly the storage battery or provide AC. The system can be designed for both off-grid and on grid
applications. Efficient and easy installation, longer life
DISADVANTAGES Large number of harmonics is produced.
Initial investment is more.
Large space is required for larger generations
Wind energy systems are noisy in operation; a large unit can be heard many kilometers away.
Efficiency is less than conventional power plants.
CONCLUSION By this project many villages can be lighted. For villages which
are much away from the construction site of large power generating stations such as hydro and nuclear can be provided power.
Also to satisfied the increasing demand of electricity with clean hybrid power station by solar –wind can be used.
