Abstarct: One of the ways to increase the energy conversion efficiency and reduce the production of pollutants in the building sector is use of cogeneration production of cooling, heat and power. These systems have different types of primitive mover. One of these prime mover is a gas micro turbine. By adding a solar receiver to the market micro-turbines, it is possible to use solar energy to provide part of the heat needed for the cycle. The components of this cycle include gas micro turbine, parabolic dishes, solar receiver, absorption chiller, auxiliary boiler, recovery boiler and heat storage tank. In this study, the cogeneration cycle of cooling, heat and power baxsed on the hybrid solar micro turbines prime mover are simulated in a software environment. The annual cycle performance is evaluated in real terms for a residential building in three cities of Tehran, Yazd and Bandar Abbas. The effect of changing the number of micro turbines, changing the area of parabolic dishes and changing the volume of the thermal storage tank has been investigated. The cost of the generated electricity of the cycle is calculated in the form of different price scenarios, and best case proposed. These scenarios include international tariffs and internal energy tariffs. . The role of the Iranian government's energy policies (including targeting subsidies and support for renewable energies) has been examined in several scenarios. The most economically advantageous situations have been introduced and some of its technical features have been evaluated. The most economically advantageous situations have been introduced and some of its technical features have been evaluated. The share of each equipment at the initial cost and maintenance cost is specified. There is also an annualized, monthly and hourly electricity and fuel consumption charts. Finally, the Levelized cost of electricity produced by the cycle is compared to the Levelized cost of electricity produced by photovoltaic systems as well as the electricity purchase tariff by the national network. The results indicate that, in many scenarios, the cost of electricity produced by the system is lower than the cost of electricity produced by photovoltaic systems, but is higher than the electricity sales tariff to the network. As the cost of electricity produced in this cycle in most scenarios is between 10% and 80% higher than the tariff for electricity sales to the global network. Compared to the electricity produced by photovoltaic systems, it is between 5% and 20% less than in some scenarios, and in other scenarios it is higher than photovoltaic electricity prices. Also, the cost of the produced power in the storage tank is 2 to 20% less than in the case of no storage tank. Therefore, considering that this technology is still in the first stages of development and is not as photovoltaic as it is, it seems to be able to take part in the energy market in the future.
