Co-simulation research and application for Active Distribution Network based on Ptolemy II and Simulink

Active Distribution Network (ADN) implements the operation and consumption of distributed energy resources (DERs), especially in the use of renewable ones, by hierarchical and distributed coordination control mode. Plenty of advanced communication and control technologies must be integrated in ADN. In this paper, a new method of co-simulation for ADN is proposed based on Ptolemy II and Simulink. In order to simulate the whole ADN, the simulation of cyber control system is implemented in Ptolemy II and the simulation of dynamics in ADN is implemented in Simulink. As the medium, MATLAB is used for data exchange between Ptolemy II and Simulink. For validation, the method is applied to simulation and analysis of a small ADN, i.e. a coordination control system of photovoltaic generation and battery energy storage. The results have proved that the method is feasible and valid.
