摘要
作为综合能源系统研究的基础,多种能源协同运行的综合能源系统多能流计算方法的研究有重要的研究价值。该文首先给出了电转热(power to heat,P2H)和电转气(power to gas,P2G)设备等耦合单元的数学模型,并根据P2H的工作特性,给出了热电联产机组(combined heat and power,CHP)联合P2H模型;之后,给出了2种电-气-热综合能源系统多能流计算的算法——含多种耦合单元的多能流联立求解算法和考虑各子系统物理特性的差异及综合能源系统的可扩展性的新型交替迭代多能流计算方法。算例分析表明,2种算法均适用于电-气-热综合能源系统的多能流计算。
As the basis of integrated energy system research,multi-energy flow calculation of integrated energy system is of great significance.Firstly,the model of P2H and P2G are given,then the model of CHP and P2H joint system is also given.Secondly,this paper presents integrated multi-energy flow calculation method.Considering the difference of physical characteristics of each subsystem and the scalability of the integrated energy system,a new alternate iterative calculation method is proposed.Two calculation methods are verified in case study.
