Cost — benefit analysis of CHP plants taking into account air cooling technologies

The ambient temperature has a negative effect on gas turbine (GT) performance, i.e., the power output of GT decreases with the increment of ambient air temperature. This negative effect is solved by means of air cooling at the input of compressor of GT unit. Mainly the air cooling technologies are widely used in the regions with hot climate to produce surplus of electricity and cover the peak demand of it. In this publication the methodology is developed for the evaluation of the economic benefit from air cooling technologies by selling surplus of electricity at electricity power exchange, i.e., the adjustment of combined and heat power (CHP) plants operation to the electricity price fluctuations through the use of air cooling technologies.
