Simulation and modeling for active distribution network BESS system in DIgSILENT

By analyzing traditional distributed energy resource (DER) modeling methods, this paper proposes a feasible method of DER modeling based on static generator in the simulation software — DIgSILENT. Behavioral model is proposed in this paper to simplify the DER model, in which simple electronic circuits or mathematical functions are used to reflect the physical characteristics of a certain model. With the application of the modeling method, the battery energy storage system (BESS) are implemented in DIgSILENT simulation environment. In each simulation case, the behavioral model as well as the control strategy is illustrated and the simulation result is analyzed in the end.
