摘　　要：中国农村地区的太阳能、生物质能等可再生能源十分丰富,但能源利用率较低,污染较为严重。针对生物质能、太阳能等清洁可再生能源接入的乡村场景,考虑热网传输特性与农业生产负荷可调性,提出了一种基于生-光耦合利用的乡村电-热综合能源系统多目标规划方法。首先,基于生物质与太阳能资源的耦合利用构建了乡村综合能源系统典型架构,同时对热网虚拟储能功能、农业生产可调控负荷以及系统关键设备进行建模分析,并提出相关运行策略;其次,构建了兼顾经济性、环保性以及能效性的乡村综合能源系统规划优化模型,考虑投资能力、设备运行和能量平衡等约束,采用基于莱维飞行的粒子群优化算法(particle swarm optimization algorithm based on Levy flight,LPSO)求解规划优化方案;最后,以中国北方某县所属村镇为例进行规划仿真,结果表明所提方法是合理且有效的。Renewable energy sources such as solar energy and biomass energy are abundant in rural areas of China,but the energy utilization rate is low and pollution is serious.Aiming at the rural scene where clean renewable energy sources such as biomass and solar energy are connected,a multi-objective planning method based on the coupling utilization of biomass and solar power for rural electricity-heat integrated energy system is proposed,considering the transmission characteristics of heat network and the adjustable agricultural production load.Firstly,a typical architecture of rural integrated energy system is constructed considering the coupling utilization of biomass and solar energy resources.At the same time,the virtual energy storage function of thermal network,adjustable load of agricultural production and key equipment of the system are modeled and analyzed,and relevant operation strategies are proposed.Secondly,a planning and optimization model for rural integrated energy system is constructed,which takes into account economy,environmental protection and energy efficiency.Considering constraints such as investment capacity,equipment operation and energy balance,the Levy flight-based particle swarm optimization algorithm(LPSO)is used to solve the planning optimization scheme.Finally,the simulation is carried out in a village and town of a county in northern China,and the results show that the proposed method is reasonable and effective.
