“DC microgrids are prone to large signal stability problems due to their low inertia and constant power load characteristics. Traditional model-based methods are computationally complex and difficult to solve. This article introduces their research progress in the field of intelligent analysis. The research team explores the application of artificial intelligence technology classifiers in stability assessment, verifies the high matching between long short-term memory network classifiers and state space equations, and provides a new solution to solve the problem of large signal stability analysis.”
