摘要
为构建安全高效、低碳清洁的可持续能源系统,提出一种计及氢能利用和综合需求响应的综合能源系统低碳协同优化调度策略。首先,为充分发挥氢能的多方面效益,构建集成氢能耦合的能源设备数学模型。其次,为发挥用户负荷的可调度能力,建立含阶梯型补贴机制的电-热-冷多能负荷的综合需求响应模型。最后,针对综合能源系统的低碳特性,在优化模型中引入奖惩阶梯型碳交易机制,建立低碳经济优化模型,并采用CPLEX对所提模型进行求解。仿真结果表明,所提调度策略能够有效降低系统总成本及碳排放量,实现系统经济、环保及灵活运行。
To build a safe,efficient,low-carbon and clean sustainable energy system,a low-carbon collaborative opti⁃mization scheduling strategy for an integrated energy system(IES)is proposed,which takes into account hydrogen en⁃ergy utilization and integrated demand response(IDR).First,to give full play to the multi-faceted benefits of hydrogen energy,a mathematical model of energy equipment with integrated hydrogen energy coupling is constructed.Second,to give full play to the dispatchability of user loads,an IDR model for power-heating-cooling multi-energy loads with a lad⁃der-type subsidy mechanism is established.Finally,in view of the low-carbon characteristics of IES,a reward and pun⁃ishment ladder-type carbon trading mechanism is introduced into the optimization model,a low-carbon economic optimi⁃zation model is established,and the proposed model is solved by CPLEX.Simulation results show that the proposed scheduling strategy can effectively reduce the system’s total cost and carbon emissions,thus realizing its economical,environmentally friendly and flexible operation.
