!sto"# During 20th and 21st centuries interest in new and

renewable energy sources especially wind energy risen

for the electricity generation.

After the 1973 oil crisis, the R sources started to

appear hence the wind energy gained significantinterest.

WIND ENERGY MANAGEMENT

The turbine’s blades are made of fiber glass blades which intentionally deform as the turbine reaches its rated output.

This deformation effect changes the shape of the blade, thus by limiting the rotation speed of the alternator and preventing damage in high winds.

Another feature of the wind turbine is a sophisticated internal regulator that periodically checks the line voltage and corrects for low voltage conditions.

The turbine’s blades are made of three fiber glass blades that will intentionally deform as the turbine reaches its rated output.

This deformation effect changes the shape of the blade, causing it to go into a stall mode,

This limiting the rotation speed of the alternator and preventing damage in high winds.

Reliability of power output for the overall system

The solar array, generates power during the summerseason, when less wind is available to reach the expectedpower output from the overall system.

The PV solar panels chosen for their ultra cleartempered glass that is manufactured for long termdurability.

Combination of PV and wind in a hybrid energy systemreduces the battery bank and diesel reuirements.

4 Presently no practical means available for

long-term storage of excess electricalenergy produced by the RE sources.

4 Due to power inverters power quality

problem becomes serious. This leads todistortion in sinusoidal waveform outputwhich further leads to harmoniccontamination and poor voltage regulation.

4 Relying on highly transient energy sourceexhibit strong short-term and seasonal

variations in energy outputs.
