摘要
为实现虚拟电厂的低碳经济运行,提出了一种考虑阶梯式碳交易和综合需求响应的虚拟电厂低碳经济调度方法。首先,研究多元柔性负荷的运行特性,建立了负荷侧综合需求响应模型;其次,在建立电转气两阶段运行模型基础上,引入氢燃料电池提高氢能利用效率;然后,将阶梯碳交易机制引入计及需求响应的虚拟电厂优化调度中,并建立了虚拟电厂低碳经济调度模型。最后,通过仿真分析表明所提方法和模型在提高系统运行灵活性的同时,改善了系统的经济性和碳排放水平。
In order to realize the low-carbon economic operation of virtual power plants,a low-carbon economic dispatch model of virtual power plants considering stepped carbon trading and integrated demand response is proposed.Firstly,considering the operating characteristics of multiple flexible loads,the load-side integrated demand response model is established.Secondly,on the basis of the the established two-stage operation model of electricity to gas,hydrogen fuel cell is introduced to improve the efficiency of hydrogen energy utilization.Then,the carbon trading mechanism is introduced into the virtual power plant,the low-carbon economic dispatch model of the virtual power plant is established.Finally,the simulation&analysis results show that the proposed model can improve the system operation flexibility,improve the system economy and reduce the carbon emission level.
