摘要
大工业生产企业能耗体量巨大,是实现碳达峰和碳中和目标的重点领域.基于对传统供能系统和转型后的光-沼-气-电系统的运行监测,分析用户侧负荷特性及典型日冷热电负荷调度特性.研究光沼发电系统的年供能侧数据及重要供能影响因子,构建综合能源系统评价指标体系,协同考虑光沼系统运行状况、经济效益、供能质量、环境效益以及能源效益五方面的因素,评价传统供能系统和光-沼-气-电系统的综合性能.结果表明:以热能需求为主的大工业生产企业,典型日负荷峰值出现在09:00-11:00或14:00-17:00,光-沼-气-电多能源系统可满足工业企业的冷热电需求;光伏系统在非不可抗力时段的平均渗透率低于10％,沼气系统在正常时段储气量占比高于50％,提升了系统供能可靠性.典型算例的评价结果验证了光-沼-气-电多能源系统评价指标体系的可行性和有效性,可为未来面向大工业企业的光-沼-气-电多能源系统的综合利用和协调发展提供借鉴.
Abstract
Large industrial producers consume a huge amount of energy and are a key area of focus for achieving peak carbon and carbon neutrality targets.Based on the operational monitoring of the traditional energy supply system and the transformed PV(photovoltaic)-biogas-gas-electricity system,and the user-side load characteristics and typical daily cooling,heating and the electricity power load scheduling characteristics were analyzed.The annual energy supply data and important energy supply influencing factors of the PV-biogas system were studied,and an evaluation index system for the comprehensive energy system was built,and five factors:PV-biogas system operation status,economic benefits,energy supply quality,environmental benefits and energy efficiency were collaboratively considered,and the comprehensive performance of traditional energy supply system and PV-biogas-gas-electricity system were evaluated.The results show these as follows.Large industrial production enterprises with mainly thermal requirement,typical daily load peaks occur at 09:00-11:00 or 14:00-17:00,the PV-biogas-gas-electricity multi-energy system can meet the cooling,heating and electricity needs of industrial enterprises.The average penetration rate of PV system is less than 10％during non-force majeure hours,and the proportion of gas storage capacity of the biogas system is higher than 50％during normal hours,and the system supply reliability is improved.The evaluation results of a typical case verify the feasibility and validity of the evaluation index system of PV-biogas-gas-electricity multi-energy system,and provide a reference for the comprehensive utilization and coordinated development of PV-biogas-gas-electricity multi-energy system for large industrial enterprises in the future.
