Abstract

The
effective usage of energy is an important factor in our country and world. The
cogeneration system is one of the methods for the effective usage of energy. The
cogeneration system in recent technology is about 30% more effective in
reducing fuel consumption and carbon footprint compared to the power and heat
production efficiency for traditional systems feeding by fossil fuels. Over the
last decade, extensive research has been undertaken on the optimization and use
of low-capacity internal combustion gas engines in micro-combined heat-power
systems. Problems such as the technology used in the micro-cogeneration system,
fuel type and performance, efficiency of the system, utilization of different
fuel types, noise, emission, maintenance problems have not been solved yet. In
recent years, intensive studies have been carried out on the fuel cells that
are being used for the cogeneration system, but the cost and the low life span
of fuel cell cogeneration systems are preventing it from becoming widespread.
With the proposed system, it will be easily applied in small scale places such
as houses, offices, campuses, hospitals, shopping malls, and electricity and
heat production efficiency will be used effectively for low CO₂
emission. In this paper, the integration of an internal combustion engine which
has 9.8kW and 1500 revolutions per minute (rpm) properties, a synchronous
generator and grid connection have been successfully achieved and the
performance results of the proposed system have been obtained by using
MATLAB/Simulink.
