Design of a Novel Synchronized Transition Control and Processor in the Loop Validation with TI C2000 DSP TMS320F28335 for Microgrid Operations

Microgrid (MG) technology is essential for power systems to be more resilient and to make use of natural energy resources to fulfill our electricity demand. MG generally operates in grid-connected and isolated mode. The crucial part of MG control is during the transition between these two modes which is called synchronize transition control (STC). In this paper, a novel reference input generation mechanism (RIGM) based control technique is proposed for improving the performance of MG during the transition from isolated mode to grid-connected mode. Extensive simulation-based studies are performed in MATLAB/SIMULINK environment to validate the effectiveness of the proposed control technique and for comparison with conventional control. Results show that the proposed technique improves the transition time performance of MG. Further, a processor in the loop (PIL) validation of the proposed control strategy has been successfully carried out using a TI C2000 DSP TMS320F28335 microcontroller.
