Study on Evaluation Method of Local-Consumption Ability of Regional Biomass Resources

The three-level consumption method of biogas in APAs (Agricultural Production Areas) was established in this paper, and the evaluation method of LCA (Local-Consumption Ability) of regional biogas was studied. Firstly, the bilevel programming model of the IES (Integrated Energy System) in APAs was established. On this basis, the APA-IES scheme was obtained and its biogas consumption was calculated. Secondly, the consumption ability of surplus biogas for power generation connected to grid was evaluated based on stochastic simulation. Thus, the biogas LCA of APAs was obtained. Finally, taking a practical distribution network as an example, the feasibility of the proposed method was verified by evaluating the LCA of biogas in APAs within the power supply area, which provided theoretical reference for the APA-IES planning and the LCA evaluation of biomass resources in rural areas.
