含需求响应与碳配额的综合能源系统优化调度

Optimal scheduling of integrated energy system with demand response and carbon quotas

为提高综合能源系统的低碳性、经济性,提出一种考虑需求侧响应与碳排放配额的综合能源系统优化模型。首先,构建综合能源系统模型,分析能源在生产、转换、传输、存储、需求5个环节中的损耗;其次,同时考虑由不同电价引导的需求侧负荷响应与无偿碳排放配额,以系统综合成本最小作为目标,建立系统优化调度模型,并采用CPLEX求解器对不同场景下的调度模型进行求解。结果表明:在应用碳配额激励下,考虑需求侧响应会使系统总成本降低,综合能源利用效率提高。该方法可有效降低系统碳排放量与经济成本,改善负荷在不同时间段的分布,为系统选择更为低碳经济的购能方式提供参考。

To reduce the cost and carbon-emission of integrated energy system,an integrated energy system optimization model considering demand-side response and carbon emission allowance is proposed.Firstly,an integrated energy system model is constructed to analyze the losses of energy in the five stages of production,conversion,transmission,storage and demand.Secondly,the demand-side load response guided by different tariffs and free carbon emission allowance are considered simultaneously,and the system optimization dispatching model is established with the objective of minimizing the comprehensive system cost,and the dispatching model under different scenarios is solved by using the CPLEX solver.The simulation results show that considering the demand-side response under the application of carbon allowance incentive leads to the reduction of total system cost and the improvement of comprehensive energy utilization efficiency.This method can effectively reduce the system carbon emissions and economic costs,and improve the load distribution in different time periods,which provides a reference for the system to choose a more low-carbon and economic way to purchase energy.
