Abstract

Abstract: Rural energy is an important part of China's energy system. With the popularization and application of biomass biogas power generation, the application prospect of rural integrated energy system is more extensive. Taking the integrated energy system in rural areas as the research object, an energy system model containing biomass biogas power generation is constructed, and the uncertainty of load and renewable energy output is described by using opportunity constraints, and a comprehensive consideration of system economy and energy utilization is proposed. Efficiency optimization runs the model. Economic optimization operation considers the lowest cost of electricity and gas. Energy efficiency considers the energy efficiency index of standard coal.In order to comprehensively consider the economy and energy utilization efficiency, the target membership function is defined to maximize the satisfaction rate. The index method converts multi-objective problems into single-objective optimization solutions. The simulation results show that the proposed method can take into account the system economy and energy utilization efficiency.

Key words: rural energy, biomass biogas power generation, opportunity constraint, energy utilization efficiency
