Dynamic Simulation of Integrated Regional Energy System Based on Bond Graph

随着风、光等不确定性较大的新能源接入,区域综合能源系统的安全稳定运行受到巨大的挑战。提出了基于键合图理论的区域综合能源系统动态仿真方法。该方法在充分考虑区域综合能源系统动态特性的基础上。建立系统主要基本元件的键合图模型。通过进一步构建区域综合能源系统的状态方程并进行求解,利用输出方程即可得到区域综合能源系统动态仿真结果。通过在某实际系统中进行算例验证,证明本文所提方法结构简明,能深入描述系统内部变化过程,为区域综合能源系统的安全动态分析奠定了坚实的理论基础。

In the wake of the integration of new energy with high instability such as wind power and solar power, the integrated regional energy system is faced with great challenges in safety and steady operation. Therefore, the paper proposes a dynamic simulation method of the system based on bond graph, and establishes the bond graph model of the basic dements by fully considering the dynamic characteristics of the system. Moreover, the paper further establishes the state equation of the system and gets the dynamic simulation results with the output equation. Finally, the analysis of examples with a actual system shows that the method has a simple structure and can describe the internal change process of the system.
