Multi-season optimization of integrated energy systems considering environmental penalties

建筑用能是能源行业的用能大户,而综合能源系统能整合各类能量,为了实现楼宇型综合能源系统的低碳、经济运行,本工作开展了综合能源系统相关优化研究。以两种不同类型建筑作为研究对象,系统包含太阳能、地热能等清洁能源,提出了以矩阵形式建模的能量枢纽模型;以建筑夏、冬两季典型日为数据基础,以典型日综合运行费用最低为目标建立优化调度模型,采用CPLEX软件结合改进NSGA-Ⅱ算法求解模型;通过算例结果表明,整体上冬季优化效果高出夏季优化效果10%左右;数据显示优化后的建筑综合运行费用节省率在15%~35%且能限制污染物排放量,具有良好的经济效益和环境效益。

Building energy consumption represents a significant portion of the energy sector,and integrated energy systems offer a way to optimize various energy sources.In order to realize the low-carbon and economic operation in building integrated energy systems,this study explores optimization strategies.Two different types of buildings are examined,incorporating clean energy sources such as solar and geothermal energy.A matrix-based energy hub model is proposed to guide the research.Based on the data from typical summer and winter days,an optimal scheduling model was established with the goal of minimizing comprehensive operational costs for these typical days.The model is solved using CPLEX software combined with an improved NSGA-Ⅱ algorithm.The results show that the optimization effect in winter is about 10%higher than that in summer.The optimized building demonstrates a comprehensive operation cost reduction ranging from 15%to 35%,while also limiting pollutant emissions,thereby providing significant economic and environmental benefits.
