Abstract
Abstract One of the ways to increase the efficiency of energy conversion and reduce the generation of pollutants in the building sector is using combined cooling, heating and power (CCHP) systems. These systems have different types of prime movers such as micro gas turbine (MGT). In this study, a novel CCHP system based on the prime mover of hybrid solar micro turbine have been simulated and the annual performance of the cycle, in actual conditions has been evaluated for a residential building in Iran. By adding solar receiver to available micro gas turbines, solar energy can provide part of the required cycle heat. The components of this cycle include: micro gas turbine, solar dishes (parabolic dishes), solar receiver, absorption chiller, auxiliary boiler, and heat recovery steam generator. The effects of changing the number of micro turbines and the area of the parabolic dishes have been studied on system performance. Also, the levelized cost of electricity (LCoE) is calculated in different prices and the best scenario is proposed. Additionally, the appropriate economic conditions are introduced and some of their technical specifications are evaluated. Ultimately, the LCoE produced by this cycle is compared to that for the photovoltaic systems.
