摘要：
Power system stability has become an increasing concern in renewable power integration because the active power generated by renewable energy varies randomly. Thus, we focus on random outside excitations in this study. Since the power obeys Non-Gaussian distribution in most case, a novel small disturbance stochastic stability analysis method based on entropy is presented. First, the dynamic model of power system with random outside excitation is established by stochastic differential equation. Then, the values of mean and mean square stability are efficiently derived by transforming the stochastic differential equation into a deterministic mean or variance equation. For non-Gaussian disturbance, entropy stability is presented by this transformation. At last, the numerical simulations are presented on a WSCC three-generator nine-bus power system with a wind farm (c) 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
