摘要:

随着我国特高压交直流工程陆续投运,系统“强直弱交”问题突出,交直流、多直流、送受端之间的交互影响日益显著,电网运行复杂度迅速增加,对电网仿真的规模、精度和速度提出了更高要求。从电力系统建模、多时间尺度仿真、数模混合实时仿真3个方面梳理了仿真技术现状,针对交直流混联大电网发展需求,分析了仿真技术面临的挑战。指出提高直流、新能源、柔性交流输电系统(flexible alternative current transmission systems,FACTS)和负荷等复杂模型的建模精度,扩大电磁暂态仿真规模,提高大规模电网仿真效率,将是提高大电网仿真能力的研究重点。

Abstract:

Along with the commissioning of UHV AC/DC transmission projects in China, the "strong DC links while weak AC grid" problem is outstanding, the interaction influences among AC/DC lines, multiple DC ones and sending/receiving ends are increasingly important, and the operation complexity of power grid is growing rapidly, so higher requirements on the scale, accuracy and speed of power grid simulation are put forward. From three aspects as power system modeling, multi-time-scale simulation and digital-analog hybrid real-time simulation, the current situation of simulation technology was explored, and the challenges from the development of AC/DC hybrid large-scale grid were analyzed. To increase the capability for large-scale power grid simulation, researches will focused on improving modeling accuracy of complex models such as DC system, renewable energy, FACTS (flexible alternative current transmission systems) and load, enlarging scale of electromagnetic simulation, and increasing efficiency of large-scale power grid simulation.

Key words: large-scale power grid simulation, system modeling, multi-time-scale simulation, digital-analog hybrid real-time simulation
