Outline
Driven by the goals of "Carbon Peak" and "Carbon Neutrality", the rural energy transition is faced with the problems of irrational energy structure, low proportion of renewable energy supply and low utilisation efficiency. For rural areas endowed with renewable energy sources such as biomass and solar energy, a rural integrated energy system (RIES) planning method considering photo-thermal assisted biogas production is proposed based on the effect of temperature on the efficiency of biogas production. Firstly, a RIES architecture is designed based on the coupled use of biomass and solar energy resources, and secondly, an economically optimal integrated rural energy planning optimisation model is constructed, which contains constraints such as energy balance and equipment operation. Finally, the example compares two planning scenarios with and without photothermal-assisted biogas production using a rural area in Shanxi as a scenario, and the results show that the biogas production rate is improved, the pressure on energy storage is alleviated, and the system planning cost and carbon emission are sig-nificantly reduced, which verifies the validity and economy of the proposed planning model.
