中文摘要:

电力电子装备大量接入后电力系统形态不断变化，传统单一仿真技术无法应对新型电力系统的复杂仿真任务。协同仿真可实现各种仿真工具之间的有效互动，可用来模拟多技术融合复杂系统的特定行为。文中提出了一种新型仿真接口设计方法，仿真接口可将不同仿真工具中建立的电网模型进行耦合，在仿真中传递耦合系统之间的阻抗信息。给出了协同仿真平台建立过程以及协同仿真的交互协议。分析了传统的V-I接口方法及传输线接口方法，将接口阻抗参数化得到通用仿真接口，并证明传统的V-I方法和传输线方法可被视为其特殊情况。展示了如何通过接口无源性来分析仿真稳定性问题，并基于接口透明度的概念来解决仿真精度问题。以118节点基准网络、接入静态无功补偿器的基准网络、接入风电场的基准网络这三个仿真场景演示了所提出的接口设计方法的实际性能。仿真结果表明，所提出的接口设计方法可有效连接不同仿真软件，保持稳定性的同时具有较高精度。

英文摘要:

After a large number of power electronic equipment is connected, the shape of the power system is constantly changing, and the traditional single simulation technology cannot cope with the complex simulation tasks of the novel power system. Collaborative simulation can realize the effective interaction between various simulation tools and can be used to simulate the specific behavior of multi-technology fusion complex systems. A new simulation interface design method is proposed in this paper. The simulation interface can couple the power network models established in different simulation tools and transfer the impedance information between the coupling systems in the simulation. The establishment process of collaborative simulation platform and the interactive protocol of collaborative simulation are given. The traditional V-I interface method and transmission line interface method are analyzed, the interface impedance is parameterized to get a general simulation interface, and it is proved that the traditional V-I method and transmission line method can be regarded as their special cases.It shows how to analyze the simulation stability through the interface passivity, and solve the simulation accuracy problem based on the concept of interface transparency. The actual performance of the proposed interface design method is demonstrated by three simulation scenarios, including 118-node reference network, reference network connected to static reactive power compensator and reference network connected to wind farm. The simulation results show that the proposed interface design method can effectively connect different simulation software and has higher accuracy while maintaining stability.
