摘要
随着能源互联网建设的发展,研究多能源耦合运行的综合能源系统已成为解决多能流问题的重要途径。提出了基于时变能量网络理论的综合能源系统动态仿真方法。该方法通过分析能量与在管线的普遍化传递规律,得到时变能量网络集中参数模型,建立了不同形式能量的等效传递方程,经选取控制变量与状态变量,求解时变能量网络方程,得到系统的状态方程及输出方程。以某综合能源系统时变能量网络为研究对象,通过设置不同扰动,对仿真结果进行分析,验证了基于时变能量网络理论建模方法的有效性,为综合能源系统的优化运行提供了重要研究手段。
With the development of energy internet construction,the study of multi-energy coupled operation of integrated energy systems has become an important way to solve the problem of multi-energy flow. A dynamic simulation method for integrated energy systems based on time-varying energy network theory is proposed in this paper. By analyzing the generalized transfer law of energy and exergy in pipelines,the time-varying energy network lumped parameter model is obtained,and the equivalent transfer equations of different forms of energy are established. The time-varying energy network equations are solved by selecting control variables and state variables,and the state equations and output equations of the system are obtained. Taking a time-varying energy network of an integrated energy system as the research object,the simulation results are analyzed by setting different disturbances,which verifies the effectiveness of the time-varying energy network theory modeling method and provides an important research method for the optimal operation of the integrated energy system.
