摘要
1:随着新能源在大电网中占比不断递增及电网设备的电力电子化,电网安全运行面临新的挑战。戴维南等值可有效简化复杂电力系统,极大提高电网安全稳定分析效率,是电网在线静态稳定态势快速评估的重要方法之一。为了有效梳理该领域已有研究成果,进而开展更加深入的探索及有效应用,对现有各种戴维南等值参数辨识方法类别、原理做了系统地归纳、总结和分析,给出了各种方法的优缺点、适用范围以及关键技术。提出了尚需解决的问题,展望了未来研究方向。
With increase of renewable energy penetration and power-electronization in large power grid, secure operation of power grid faces great challenge. Thevenin equivalent is a core method for rapid stability situation assessment of power grid online. Thevenin equivalent can simplify complex power systems, greatly improving efficiency of security and stability analysis. In order to effectively conclude existing research results within the field, conduct more in-depth exploration and apply them effectively, existing Thevenin equivalent parameter（TEP） methods and principles are summarized and analyzed systematically. Advantages and disadvantages, application scopes and key technologies of various TEP methods are given. Besides, this paper puts forward problems yet to solve and pointed out future research direction.
