摘要: |
综合能源系统(Integrated Energy System, IES)中存在复杂的能量耦合关系和多重扰动变量,这给多能流联合潮流计算提出了新的挑战。首先从耦合元件和耦合变量的角度,分析了运用分解法求解联合潮流的思路。然后提出了基于消息总线的电、热、气联合潮流的协同仿真架构,建立了仿真子系统之间的消息发布与订阅机制。接着,为了满足仿真子系统之间迭代的要求以及时间序列潮流计算的要求,提出了IES协同仿真的时间同步规则。最后,以一个典型的区域IES为例进行了仿真计算。结果表明,该方法能支持多能流的时间序列潮流计算,且实现了协同仿真的收敛性。 |

Abstract: |
There are complex energy coupling relationships and multiple disturbance variables in Integrated Energy Systems (IES). These pose new challenges to the calculation of multi-energy flow. First, the idea of solving combined energy flow by a decomposed method is analyzed from the point of coupling elements and coupling variables. Secondly, a cooperative simulation framework of electric, heat and gas energy flow based on a message bus is proposed, and the mechanism of message publishing and subscribing between simulation subsystems is established. Then, the time synchronization rules of IES collaborative simulation are proposed for the requirements of inter-iteration between subsystems and energy flow calculation of time series. Finally, a typical regional IES is taken as an example for simulation calculation. The results show that the proposed method can support a multi-function flow time series power flow calculation, and achieve convergence of collaborative simulation.
