A Case Study on the SILS Implementation of a Grid-Connected and Islanded Microgrid

This study proposes a Python-MATLAB/Simulink based Software-in-the-Loop Simulation (SILS) framework for the pre-validation of microgrid control and operational strategies. The framework integrates a Supervisory Control And Data Acquisition (SCADA) system, enabling real-time monitoring and SILS-based verification of control strategies. To evaluate its effectiveness, the proposed framework was implemented on a IEEE 13-bus system testbed. The accuracy of the SILS framework was validated by comparing the reference inputs from the optimal operational scheduling algorithm with the outputs of the testbed simulation. Furthermore, the results from the islanded microgrid operation scenario demonstrate that the system maintains stability, validating the framework's scalability.
