考虑碳交易的综合能源系统在不同配置情景下的运行分析

Operation Analysis of Integrated Energy System Considering Carbon Trading under Different Configuration Scenarios

大量分布式可再生能源发电机组的部署和碳排放交易的成本可对综合能源系统的运行产生重要影响。首先,针对电热综合能源系统,本文建立了考虑负荷需求、风速、太阳辐射强度和碳排放交易成本等不确定性因素的热网-主动配电网耦合模型。其次,本文采用多时段蒙特卡洛树状仿真的随机方法,分析可再生能源发电集成度和碳排放交易成本对系统运行总成本的影响。最后,本文以新疆能源系统为对象进行了算例分析。算例仿真结果表明:在新能源补贴下滑的大环境下,碳排放交易的实施可以为政府推进可再生能源装机提供新的动力。

The deployment of numerous renewable distributed generators(RDGs)and the cost of carbon emissions trading will result in an important impact on the operation of the integrated energy system.Firstly,in the light of electric heating integrated energy system,the coupled model of heat network-active distribution network is set up,which takes into account uncertainties such as load demand,wind speed,solar radiation intensity and carbon emission trading cost.Secondly,the stochastic method of multi-period Monte Carlo tree simulation is used to analyze the influence of renewable energy power generation integration and carbon emission trading cost on the total system operation cost.Finally,analysis is made by taking Xinjiang energy system as an example.The simulation results show that the implementation of carbon emission trading can provide new impetus for the government to promote the installation of renewable energy in the context of declining new energy subsidies.
