MatLab-OpenDSS co-simulation environment: An alternative tool to investigate DSG connection

This work presents a hybrid simulation tool that combines quasi-static and electromagnetic transients models for faster and accurate results. The electrical network is splited in two different areas and they are solved by OpenDSS and Sim-PowerSys/Matlab programs, respectively. During the simulation, an Intranet Server controls the data transaction between the two simulation environments by using a TCP/IP protocol. The proposed methodology is demonstrated by integrating three PV power plant into different points of a distribution feeder based on 13-bus IEEE benchmark. Simulation results are used to validate the accuracy of the proposed method and evaluate the time reduction of the hybrid simulator when it is compared to the time when the same electrical system is fully simulated in the transient electromagnetic program.
