Abstract
An operational control system was proposed
in order to control and supervise the operations
of PV/Wind/Hydro-Diesel hybrid power generation
systems at GSM base station sites. The control system
was developed in such a way that it coordinates when
power should be generated by renewable energy (PV
panels, wind turbine and hydro turbine) and when it
should be generated by diesel generators. This system
is intended to maximize the use of the renewableenergy
system while limiting the use of the diesel
generator. The diesel generator is utilized only when
the demand cannot be met by the renewable energy
sources including battery bank. A developed control
system was used to study the operations of the hybrid
PV/Wind/Hydro-Diesel energy system. The control
simulation shows that the developed control system
reduces the operational hours of the diesel generator
thereby reducing the running cost of the hybrid energy
system and pollutant emissions. From the simulation
result, the developed control system reduces the
operational hours of the diesel generator from 7,106
h yr-1 to 1,786 h yr-1 saving 28,087 L of fuel annually,
and thereby preventing about 73,961 kg of CO2 from
entering the environment of the studied area. This control system is suitable for use in a more complex
hybrid system.
