摘要

农村地区能源绿色转型发展是构建现代能源体系的重要组成部分,而引入化工类产业在促进乡村振兴的同时,也带来严重的污染问题.因此,研究农村化工生产脱碳及园区能源结构优化对实现"双碳"目标和农村现代化具有重要意义.该文提出一种考虑电转氨和生物质废能转换的农村化工园区综合能源系统低碳调度方法,通过利用富余可再生资源产生绿氨,考虑碳-氨耦合过程,将绿氨与碳捕集设备联合运行促进化工生产,同时利用生物质能替代燃煤发电,三者构建化工园区联合生产单元,进而降低园区碳排放及运行成本.首先,建立电转氨两阶段模型和生物质废能转换模型及其能流关系.其次,构建化工园区联合生产单元,分析其电、热、气以及碳能量耦合特性.再次,引入有机朗肯循环(organic Rankine cycle,ORC)余热发电和负荷侧综合需求响应,综合优化化工园区联合生产单元.最后,以化工园区运行总成本最低为目标,通过不同场景对比分析证明所提调度方法对化工园区有较好的改善作用,可为农村产业结构调整和能源转型提供理论支持.

Abstract

The green transformation and energy deve lopment in rural areas are important in building a modern energy system.However,the introduction of chemical industries not only promotes rural revitalization but also brings serious pollution problems.Therefore,it is important to study the decarbonization of rural chemical production and the optimization of energy structures in the park to achieve the goal of"double carbon"and rural modernization.This paper proposes a low-carbon dispatch method for the integrated energy system in rural chemical industry parks considering power to ammonia and biomass waste energy conversion.Green ammonia is generated by using surplus renewable resources.Considering the carbon-ammonia coupling process,the combined operation of green ammonia and carbon capture system promotes chemical production.At the same time,biomass energy replaces coal-fired power generation,and the three build a joint production unit of the chemical park,thereby reducing carbon emissions and park costs.Firstly,A two-stage model of power to ammonia and a biomass waste energy conversion model is constructed,and their energy flow relationship is established.Secondly,the joint production unit in the chemical industry park is constructed,and the coupling characteristics of electricity,heat,gas,and carbon power are analyzed.Thirdly,the organic Rankine cycle waste heat power generation and load-side comprehensive demand response are introduced to comprehensively optimize the joint production unit of the chemical industry park.Finally,aiming at the lowest total cost of the chemical industry park operation,the comparative analysis of different scenarios proves that the proposed scheduling method has a better improvement effect on the chemical industry park,which can provide theoretical support for the adjustment of rural industrial structure and energy transformation.
