摘要
针对具有电、氢充能需求的高速公路服务区内的多能源负荷需求及服务区与周边生活垃圾处理需求,提出一种全可再生能源供能的"无废"电-氢充能服务区多源微网模型。首先,在电制氢、燃料电池、热解炉等多能源转换与存储设备的能量输入输出特性模型基础上,建立无废充能服务区多源微网(zero-waste charging service area multi-energy microgrid,ZWSA-MEMG)模型;其次,研究ZWSA-MEMG中多种能源转换、存储特性及多能流协调关系,建立基于高速公路充能服务区多源微网功率平衡、充能时间、多源负荷供能可靠性、可提供的电网调节性能等约束下的运行成本优化模型及其求解方法。最后,以我国西北某高速服务区实际多能源运行数据为基础,建立"无废"电-氢充能服务区多源微网优化运行仿真模型,算例仿真结果表明,该文提出的ZWSA-MEMG优化运行模型可有效提升具有垃圾处理能力的电-氢充能多能源系统的经济性,并可为电网提供较好的调节特性。
In order to solve the issue of the requirements for multi-energy loads in a highway service area with electrical and hydrogen charging requirements, and to meet the demands for the disposal of household waste generated in the service area and its surroundings, a electricity-hydrogen charging service area multi-energy microgrid model based on all renewable energy supply was proposed in this paper. Firstly, on the basis of energy input and output characteristic models of electric hydrogen production, fuel cell, electric boiler and pyrolysis furnace, the model of the zero-waste-service area multi-energy microgrid(ZWSA-MEMG) was established. Secondly, the multi-energy conversion, storage characteristics and multi-energy current coordination in the ZWSA-MEMG were studied. Based on the constraints of power balance, charging time, energy supply reliability of multi-energy loads, available grid regulation performance in the ZWSA-MEMG, the operation cost optimization model and its solution were established. Finally, taking the actual multi-energy operation data of an expressway service area in Northwest China as an example, optimization operation model of ZWSA-MEMG was established. The results of the example show that the optimization operation model of ZWSA-MEMG proposed in this paper can effectively improve the economy of the electricity-hydrogen charging multi-energy system with the ability of waste disposal, and provide better regulation characteristics for grid.
