Introducing solar utilization technology into multi-generation system is an appropriate way to further replace the role of fossil fuel for carbon neutral. However, the intermittency of solar energy is an urgent problem for researchers to solve. Thus, a novel seasonal biomass-driven multi-generation system integrated with photovoltaic/thermal collectors and ground source heat pump is developed. The integrated system is composed of four main parts: photovoltaic/thermal system, Brayton cycle, biomass gasification and ground source heat pump. In addition, photovoltaic/thermal system can improve performance of ground source heat pump and increase mass flowrate of domestic hot water in daytime. To investigate seasonal performance of integrated system, thermodynamic and economic analyses are carried out in this study. At designated point, energetic and exergetic efficiencies of proposed system are 86.44% and 17.12%, respectively. Compared to the performance variations on summer and winter typical day, the results indicate that thermodynamic performances show reverse trend in daytime. In addition, the levelized cost of productions in spring, summer, autumn and winter are 0.189, 0.204, 0.188 and 0.183 $/kWh, respectively. As a result, the proposed system provides an alternative way to make full use of multiple renewable energy and achieve more suitable operation modes.
