INTRODUCTION TO HYBRID ENERGY SYSTEM
• HES is a system that combines at least one controllable
(conventional) source and non controllable (nonconventional/
renewable) source.
• They provide energy and at the same time can address
limitations in terms of fuel requirement flexibility, efficiency,
reliability, reduced emissions, power quality.
• HES main parts are PV system, wind energy system, diesel
generator and optional batteries.
• Both solar and wind energy conversion systems are developed
with maximum power point tracking (MPPT) control, power
electronic interface and voltage regulators.
• Wind power is unreliable, the combination of solar and wind
energy system is preferred to improve the reliability.
Contd..
• To enhance the reliability further we use a diesel generator.
• Diesel generator is operated in parallel with the wind turbine
and solar energy system to increase the maintenance
flexibility, efficiency and distribute the electric load more
optimally.
SITE STUDY FOR HES
• Performance of HES is dependent on the environmental conditions.
• The availability of solar PV or wind power is highly influenced by
topography and weather conditions at a site.
• HES site selection requires the adequate availability of both solar
insolation and wind speed.
• Measurement of the various parameters including weather monitoring
on the site location e.g. solar insolation, ambient temperature, wind
speed and relative humidity using sensors (anemometer, pyranometer
etc.).
• Site study can indicate optimal combination of wind, solar, diesel
generation to provide power at lowest cost.
• Weather monitoring is also done on site.
