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.

在建筑行业中提高能源转换效率并减少污染物产生的方法之一是使用制冷，制热和动力（CCHP）组合系统。这些系统具有不同类型的原动机，例如微型燃气轮机（MGT）。在这项研究中，对基于混合太阳能微型涡轮机原动机的新型CCHP系统进行了仿真，并评估了伊朗某住宅建筑在实际条件下的年循环性能。通过将太阳能接收器添加到可用的微型燃气轮机，太阳能可以提供一部分所需的循环热量。该循环的组成部分包括：微型燃气轮机，太阳能碟（抛物线碟），太阳能接收器，吸收式制冷机，辅助锅炉和热回收蒸汽发生器。已经研究了改变微型涡轮机数量和抛物面的面积对系统性能的影响。同样，以不同的价格计算平准化的电费（LCoE），并提出最佳方案。此外，引入了适当的经济条件并评估了其中的一些技术规格。最终，将此循环产生的LCoE与光伏系统的LCoE进行比较。
