考虑碳排放的多站融合系统日前优化运行

Day-ahead optimal operation of multi-station fusion system considering carbon emission

提出了一种多站融合系统的日前优化运行模型,目的在于提升融合站运行经济性的同时减小碳排放量、保证供电可靠性。首先,对各子站建立数学模型;然后,建立融合站优化运行的目标函数,主要包括融合站日运行成本最小和碳交易成本最小;接着,建立融合站运行的约束条件;最后,为了快速得到实用的运行策略,采用CPLEX工具对模型进行求解。通过仿真求解,验证模型的有效性和合理性,同时分析了融合新能源站和储能站的投资回收期,为后续其他子站的融合以及多站的扩建、发展提供一定的理论研究基础。

A day-ahead optimal operation model of multi-sta-tion fusion system is proposed to improve the operation economy of the fusion station while reducing carbon dioxide emission and en-suring the reliability of power supply.Firstly,the mathematical model of each substation is established.Then,the objective func-tion of optimal operation of the fusion station is established,which mainly includes the minimum daily operation cost and the mini-mum carbon trading cost of the fusion station.Then,the constraint conditions for the operation of the fusion station are established.Fi-nally,CPLEX is used to solve the model in order to obtain the prac-tical operation strategy quickly.The validity and rationality of the model are verified through the simulation solution.Furthermore,the payback period of the fusion new energy station and the energy storage station is analyzed,which provides a certain theoretical re-search basis for the subsequent fusion of other substations and the expansion and development of multiple stations.
