摘　　要：为了解决生物质电厂秸秆燃烧飞灰的处理问题以及如何实现沼气的高效制备与沼液沼渣的充分利用等问题,本文将生物质直燃发电机组与沼气池耦合,构建了生物质电热气肥多联产系统,并对系统设备进行特性建模;其次,考虑系统经济性及温室气体减排特性,建立了生物质电热气肥多联产系统多时间尺度运行优化模型,并采用人工蜂群智能优化算法求解;最后,基于算例分析了所提出系统的优势以及日前、日内调度中各设备出力特点。研究结果表明本文构建的系统利用多能互补特性,可有效提高沼气池的供能效率,促进了生物质资源的消纳,使得系统拥有较好的经济性和温室气体减排特性。In order to solve the problem of ash treatment in biomass power plants and how to achieve the efficient preparation of biogas and the full utilization of biogas sludge,a biomass-based electricity,heat,gas and fertilizer cogeneration system is constructed,and a mathematical model of the system equipment is established.Secondly,a multi-time scale operation optimization model of the biomass-based electricity,heat,gas and fertilizer cogeneration system is established and solved by an artificial bee colony intelligent optimization algorithm.Finally,the advantages of the proposed system and the characteristics of the equipment output in the day-ahead and intra-day scheduling are analyzed based on the calculation examples.The research results show that the system can effectively improve the energy supply efficiency of biogas digesters by using the multi-energy complementary characteristics,so that the biogas digester output is maintained at a relatively high level throughout the day.This promotes the consumption of biomass resources and enables the system to have good economic and greenhouse gas reduction characteristics.
