Because of the difficulties of biomass fuel collection and unstable supply in the actual operation of the integrated energy system (IES) centered on biomass cogeneration units, this paper proposes an IES planning method that considers the price elasticity of biomass supply. Firstly, according to the biomass purchase price elasticity theory, a straw collection cost model is established and introduced into the two-level planning of the industrial park IES. Secondly, the upper-level model uses equipment planning capacity and straw purchase price as optimization variables to pursue the minimum annualized comprehensive cost; the lower-level model uses equipment hourly output and straw consumption as optimization variables to pursue the minimum annual operating cost that takes into account the price flexibility of straw collection costs, and the particle swarm optimization and the CPLEX toolbox are used to solve the problem. Finally, a typical industrial park in Jilin Province is taken as an example to verify that the proposed planning method is more suitable for the actual situation of the project and has a more superior economic efficiency.

Key words: integrated energy system (IES), biomass energy, price elasticity, two-level planning
