N2 - With the increasing penetration of distributed generators (DGs) and demand for electricity, the security and stability of distribution networks is facing new challenges due to the randomness of DGs and loads. A dynamic simulation method taking the stochastic disturbance influence into account is proposed for active distribution networks (ADNs). Firstly, stochastic models of the irradiance, wind speed and load fluctuations are developed to simulate the stochastic characteristics of DGs and loads. Then, a stochastic dynamic simulation method based on SUNDIALS is proposed. Finally, case studies based on a medium and low voltage ADN are performed to verify the proposed method. Compared with the deterministic simulation methods, the proposed method based on SUNDIALS and the parallel algorithm is better able to reflect the stochastic characteristics of ADNs while meeting the requirements of high simulation accuracy.
