摘要
双碳目标下,构建以天然气储气库为中心的综合能源系统并进行其优化配置有利于提高其综合能源利用效率和经济运行水平。针对天然气储气库的生产特性和用能特点,构建了考虑余热利用的储气库综合能源系统,并基于粒子群算法和CPLEX求解器提出了针对储气库综合能源系统的双层容量优化配置方法,最后利用TOPSIS对该系统的综合能源系统整体优劣程度进行评价。结果表明余热利用系统将有效提高综合能源系统的供能效率并降低用能成本。考虑到天然气储气库注采周期用能以及负荷的不均衡性特点,余热利用系统与燃气轮机发电机组的结合将显著提高天然气储气库综合能源系统的综合性能。
Under the dual carbon goal,building a comprehensive energy system centered on natural gas storage and optimizing its configuration is conducive to improving its comprehensive energy utilization efficiency and economic operation level.Based on the production characteristics of gas storage of natural gas and can use characteristics,is established considering the residual heat utilization gas storage integrated energy system,and based on particle swarm optimization CPLEX algorithm and can solver is proposed for the double layer capacity of gas storage integrated energy system optimization configuration method,finally using TOPSIS to integrated energy system of this system to evaluate the overall quality.The results show that the waste heat utilization system can effectively improve the energy supply efficiency and reduce the energy consumption cost of the integrated energy system.Considering the unbalanced characteristics of energy consumption and load in the injection-production cycle of natural gas storage,the combination of waste heat utilization system and gas turbine generator set will significantly improve the comprehensive performance of the integrated energy system of natural gas storage.
