摘要:

为了高效利用炼焦副产的焦炉煤气资源,同时满足用户多样化能源的需求,构建了以焦炉煤气为燃料的分布式多能联供系统,在考虑一次能源消耗、环境补偿成本和运行维护费用基础上,建立了能源协同高效利用的系统运行优化调度模型.在满足用户负荷和供能设备高效利用的基础上确定约束条件,采用改进的遗传算法,以日运行成本最低为优化目标,对系统在不同季节典型日的运行调度进行了优化研究.结果表明,所构建的多能联供系统具有良好的经济性,在优化调度条件下运行时,春夏秋冬四季典型日内的运行成本分别为3 480.17,4 752.25,3 168.23和4 464.02元,能源综合利用效率分别为65.10%,57.82%,67.25%和70.12%.与传统的以天然气为燃料的冷热电联供系统(combined cooling,heating and power,CCHP)相比,尽管系统的能源综合利用效率稍低,但在运行成本上有一定的优势,适合我国“煤多气少”的能源结构.

Abstract:

To effectively utilize by?product coke oven gas and meet the diverse energy demands of users, a distributed multi?energy cogeneration system fueled by coke oven gas was developed. The system incorporates primary energy consumption, environmental compensation costs, and operational and maintenance expenses to create an optimized operational model for efficient energy collaboration. Constraints were established to ensure that user demands are met and equipment is utilized efficiently. An enhanced genetic algorithm was employed to minimize daily operational costs, with optimized scheduling performed for typical days across different seasons. The results demonstrate that the multi?energy supply system is economically viable, with operational costs recorded at 3 480.17, 4 752.25, 3 168.23, and 4 464.02 yuan for typical days in spring, summer, autumn, and winter, respectively. The system’s energy comprehensive utilization efficiencies reached 65.10%, 57.82%, 67.25%, and 70.12% for the same periods. Although the energy utilization efficiency is slightly lower compared to traditional natural gas?fueled CCHP system, the proposed system offers cost advantages and aligns with China’s “more coal and less gas” energy supply situation.

Key words: coke oven gas, multi?energy combined supply system, operational cost, optimal scheduling
