Photovoltaic poverty alleviation not only makes full use of solar energy resources, but also promotes rural poverty alleviation and development and new energy utilization. There is a lack of research on the optimal allocation of rural comprehensive energy. In view of the problem that Chinas rural comprehensive energy construction cannot copy the urban energy structure. Based on the background of Chinas rural photovoltaic poverty alleviation, combined with the rural biogas recycling mode, a rural integrated energy station with the characteristics of rural industrial development was innovatively designed, and the optimization allocation method was put forward. Considering the cost and benefit of photovoltaic poverty alleviation, biogas recycling and the constraints of electricity, heat and cold in rural energy stations, the model optimized the capacity of gas turbine, gas boiler, electric cooler and energy storage device. Taking a poverty-stricken village in the north as the research object, using the local photovoltaic poverty alleviation policy support and the characteristics of rich biomass resources, the rural integrated energy station equipment was optimized, and the income of rural integrated energy station based on photovoltaic poverty alleviation was analyzed. The results showed that the optimal allocation of rural integrated energy station proposed was reasonable and effective, which can provide theoretical and technical support for future rural integrated energy planning and green industry poverty alleviation.
