摘要/Abstract

摘要： 农村能源是中国能源体系的重要组成部分，随着生物质沼气发电的推广应用，农村综合能源系统的应用前景更加广泛。以农村地区综合能源系统为研究对象，重点构建了含生物质沼气发电的能源系统模型，采用机会约束对负荷及可再生能源出力不确定性进行描述，提出综合考虑系统经济性与能源利用效率的优化运行模型。经济优化运行考虑了系统购售电购气费用最低。能源利用效率考虑了标准煤能效指标。为综合考虑经济性与能源利用效率，通过定义目标隶属度函数，利用最大化满意度指标法将多目标问题转化成单目标进行优化求解。仿真结果表明所提方法能够统筹兼顾系统经济性与能源利用效率。

关键词: 农村能源, 生物质沼气发电, 机会约束, 能源利用效率

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
