The model is developed using MATLAB/Simulink® and the real-time test environment is composed of an OPAL-RT simulator. In offline and RT-Lab-based online simulations, the model is investigated for grid-feeding, grid-supporting, grid-following and grid-forming operations of the microgrid inverters. The MMC-DSTATCOM operation is tested for different reactive power control scenarios both in grid-following and grid-forming modes. In this study, one of the major challenges that affects real-time simulations is employing switching power electronic converter models and their controls with significantly low overruns in the RT-Lab platform. It is observed that microgrid and switching converter operations are successfully realized in real-time simulations with significantly low overruns for 25mumathrm{s} step-size. © 2022 IEEE.en10.1109/PEMC51159.2022.9962933info:eu-repo/semantics/closedAccessMicrogridsMMC-DSTATCOMoverrunsreal-time simulationRT-LABElectric loadsElectric power system controlMATLABMicrogridsPower controlPower convertersReactive powerRenewable energy resourcesSimulation platformStatic synchronous compensatorsDistribution static compensatorLow voltage microgridMicrogridModular multilevel converter-distribution static compensatorModularsMultilevel converterOverrunReal-time simulation modelsRealtime simulation (RTS)RT-LABElectric power distributionConference Object5225292-s2.0-85144055284
