Optimal operation of biomass integrated energy system in villages and towns

Abstract

In order to improve the efficiency of energy utilization, improve the energy structure of villages and towns, and promote the efficient application of biomass energy in villages and towns, an integrated energy system (IES) with biomass energy as the core is constructed, and a two-stage optimization method of IES considering the loss of heat supply network is proposed. In the first stage, considering the loss of heat supply network and taking the minimum total heat supply as the objective, the outlet temperature of multi heating equipment is optimized. Then, the output mechanism of biomass cogeneration is analyzed and its output model is established. Considering the whole process of biomass transportation, storage and treatment, the energy supply cost model is established. In the second stage, the output operation optimization of each equipment of IES is carried out with the goal of maximum daily income. The results show that the model is effective, the complexity of the problem is reduced by two-stage optimization, the biomass utilization efficiency is improved by cogeneration, and better benefits can be obtained by constructing biomass energy IES.
