Abstract

By utilizing the abundant solar and biomass energy resources in the local area, the research has innovatively designed a new type of distributed multi generation system: combined heating, power, biogas, and fertilizer (CHPBF). This system combines sustainable energy with circular agriculture, while solving the problem of clean energy supply for local users, achieving harmonious coexistence between energy production and circular agriculture. A theoretical dynamic model of the CHPBF system was built for 26 buildings in Wuwei City, Gansu Province. Annual techno-economic analysis and comprehensive environmental benefits were investigated using Python programming language with accurate model. The annual biomass input for the optimal system was 14,283,100 kWh, with 32.20 % used for heating and 67.80 % for the anaerobic fermentation process at the biogas station. Methane produced through anaerobic fermentation accounts for 5,950,000 kWh, or 41.66 % of the total biomass input. The system's annual solar energy input was 9,619,300 kWh. Annual analysis revealed that the system generates ample energy for 582 households, with a surplus of 1,630,000 kWh of electricity for the grid. It can process biomass waste, reducing annual CO2 emissions to 0.95 tons per person.
