Multi-objective operation optimization of wind-solar-thermal-storage integrated energy system considering carbon capture
摘要
Abstract
Against the conflict between carbon emission and operation cost in integrated energy systems,a multi-objective optimal scheduling method for wind-solar-thermal-storage integrated energy system considering carbon capture is proposed.It explores how carbon capture equipment affects the renewable energy consumption,carbon emissions,and operating costs.Taking the electric load data of a typical day in a specific area as a reference and the improved IEEE 30-bus system as the example,the system economy is optimized.The results show that,compared with the wind-solar-thermal and wind-solar-thermal-storage scenarios without carbon capture,the operating costs of the integrated energy system considering carbon capture reduces by 5.19%and 2.86%respectively on typical days,and the carbon emissions decrease by 1 159 t and 1 013 t,respectively.The consumption rate of wind and solar power generation increases by 5.01%and 2.82%,respectively.Moreover,with the minimum system operation cost and carbon emissions as the optimization objectives,the non-dominated sorting genetic algorithm Ⅱ is used for multi-objective optimization,and the system scheduling optimization scheme under different target weights is obtained by combining with the linear weighted sum method.The study finds that,increasing the weight of carbon emission target reduces the carbon emissions but raises the system operation costs and the cost per unit of carbon emission reduction.Specifically,when the target weight of carbon emissions rises from 0 to 0.5,the carbon emissions decrease by 5 159 t and the operating costs increase by 205 466 yuan.The carbon emission reduction cost per unit increases the least when the target weight shifts from 0.4 to 0.5.The most significant emission reductions occur when the target weight is within[0.2,0.4].The multi-objective optimal scheduling method considering carbon capture proposed above provides a reference for decision makers when weighing system carbon emissions and operating economy.关键词
