Research on Verification Method of Electromechanical Transient Simulation Model of Battery Energy Storage System

In this paper, it is focused on the electromechanical transient simulation model and parameters verification of battery energy storage system under the condition of grid-integration. Based on the comparison between measure curve and simulation cure, the verification method and steps are proposed including: model simulation, experimental test and model evaluation, etc., and an actual case is analyzed to verify the validity of the method. Research shows that as an important flexible source, the accuracy of simulation model parameters is particularly important for dispatching and operation control of battery energy storage system. The above-mentioned verification method has important practical needs and engineering application value for grid-integration simulation decision of battery energy storage system.
