Abstract: This paper proposed a solid oxide fuel cell-micro gas turbine-combined cooling, heating and power system (SOFC-MGT-CCHP) coupled with solar energy, the models of both the SOFC-MGT-CCHP system and the solar hot water system are established and coupled together. Then, taking a hotel user as an example, three typical operating strategies were proposed according to the energy consumption characteristics of users in different seasons. And comparative studies were made based on system operation modes such as heating by electricity, electricity by heat, and whether to couple with solar energy, etc. The research results show that the SOFC-MGT-CCHP system coupled with solar energy is the most energy- efficient when it operates at the mode of heating by electricity. In the case of meeting the energy requirements of users, compared to the operation mode of electricity by heat that without integration with the solar energy, the system's average daily primary energy saving rate, primary energy utilization rate and carbon dioxide reduction rate are increased by 2.88%, 14.2% and 3.76% respectively. And compared with the operation mode of heat by electricity that without integration with the solar energy, they are increased by 26.31%, 83.05%, and 26.53% respectively.
