    The increase of renewable energy sources (RESs), especially wind power and photovoltaic, is bringing different fault features to the power system compared with the traditional synchronous generator, resulting in the urgent need for precise fault analysis. According to the sequentially activated fault features, the short circuit characteristics of RES can be divided into three fault stages. Within ...

    Partitioning a complex power network into a number of sub-zones can help realize a “divide-and-conquer” management structure for the whole system, such as voltage and reactive power control, coherency identification, power system restoration, etc. Extensive partitioning methods have been proposed by defining various distances, applying different clustering methods, or formulating var...

    Resilient power systems urgently need real-time evaluation of their operational states. By mining the characteristics of the grid operational data and mapping them to the operational state, this paper proposes a method to evaluate the real-time state and the evolution direction of power systems. First, the state evaluation matrix is constructed using nodal voltages. Then, from the data-driven pers...

    The provision of wind farm (WF) grid codes (GCs) has become imperative for sustained grid operations, especially for WFs with permanent-magnet synchronous generator (PMSG) wind energy conversion system. Numerous techniques have been developed for executing GC requirements in the event of grid faults. Among the methods, an intriguing strategy is to enhance the performance of back-to-back (BTB) conv...
