Research on Active Defense Strategies for Asynchronous Interconnected Power Grids Based on Two-Stage Robust Optimization

To address potential natural disasters or man-made attacks on asynchronous interconnected power grids, this paper proposes an active defense strategy based on game theory. A two-stage robust optimization model for a three-layer sequential game of DAD is established, and is solved using C&CG. The results indicate that a pre-allocation of defense resources can significantly reduce system losses after a fault, with a notable enhancement in system robustness, especially in DC back-to-back grids.
