Real-Time Co-Simulation Framework for Power Distribution System Analysis and Visualization Using OpenDSS and MATLAB/Simulink

The integration of renewable energy sources, battery energy storage systems (BESS), and smart grid technologies has increased the power distribution system's complexity, requiring advanced simulation and visualization methods. This paper introduces a co-simulation framework combining OpenDSS and MAT-LAB/Simulink to enhance the analysis and visualization of power system dynamics. The framework utilizes Simulink's capabilities to visualize and control real-time interactions and responses of power systems under various scenarios, including Additive White Gaussian Noise (AWGN) disturbances, line control operations, fault analysis, and peak shaving. Through dynamic data exchange between OpenDSS (Open Distribution System Simulator) and Simulink, the framework provides clear insights into voltage stability, power flow fluctuations, and BESS performance. The results highlight the effectiveness of the proposed framework in enhancing system monitoring and providing clear insights into dynamic behaviors under varying operational conditions. By leveraging the strengths of co-simulation, this approach supports grid stability assessments, fault analysis, and decision-making for grid optimization and renewable energy intearation.
