Optimal scheduling of integrated energy system considering integrated demand response and reward and punishment ladder carbon trading

随着能源需求急剧上升及环境污染日益严重,安全高效、低碳清洁的能源形式已成为能源发展的主流方向,而综合能源系统是降低环境污染排放、提高能源利用效率的有效途径之一。为了实现综合能源系统经济、低碳运行,本工作提出一种基于奖惩阶梯型碳交易机制和综合需求响应策略的综合能源系统低碳优化调度策略。首先,针对多元负荷的柔性特性和可调度价值,提出了考虑冷-热-电多元负荷的综合需求响应模型,并在此基础上,提出了响应补偿机制;其次,针对可再生能源的不确定性,采用拉丁超立方抽样法结合Kantorovich场景削减法生成光伏、风电和负荷的预测出力典型场景,并在优化调度模型中引入奖惩阶梯型碳交易成本,建立了以系统运行成本、响应补偿成本以及阶梯型碳交易成本之和最低的优化目标函数。最后,采用CPLEX工具箱对所提模型进行求解。算例仿真设置了不同场景,分析了综合需求响应策略和奖惩阶梯型碳交易机制对综合能源系统运行优化、节能减排的影响,验证了所建立的模型和策略能有效兼顾系统的经济、环境效益。

Safe,efficient,low-carbon,and clean energy has become the dominant path of energy development,and an integrated energy system is one of the most effective strategies to minimize pollution emissions and enhance energy efficiency.To realize the economic and low-carbon operation of the system,this study proposes a low-carbon optimal scheduling strategy for an integrated energy system considering a reward and punishment ladder carbon trading mechanism and an integrated demand response strategy.To begin,an integrated demand response model for cooling,heat,and electricity multiple loads is provided based on the flexible properties and schedulable value of multiple loads.A response compensation technique is developed on this basis.Second,addressing the uncertainties of renewable energy,The Latin hypercube sampling method and kantorovich scenario reduction method are used to generate typical scenarios of the predicted output of photovoltaic,wind power,and load and the reward and punishment stepped carbon transaction cost is introduced into the optimal scheduling model,and the optimization objective function with the lowest sum of system operation cost,response compensation cost,and carbon transaction cost is established.Finally,the CPLEX toolbox solves the given model.The impacts of the integrated demand response technique and the reward and punishment stepped carbon trading mechanism on the operation optimization,energy conservation,and emission reduction of the comprehensive energy system are evaluated in the example simulation.It has been demonstrated that the developed model and approach can effectively account for the system’s economic and environmental advantages.
