Performance of Microgrid Systems on Multiple Dynamic Loads Penetration

Microgrids (MGs) have emerged as a promising solution to enhance the reliability and sustainability of modern power distribution systems. In recent years, there has been a growing interest in interconnecting multiple microgrids to create more resilient and efficient energy networks. However, the performance of interconnected microgrids under various dynamic load scenarios remains a critical research area. In this paper, problems like low-frequency oscillations (LFOs) and the dynamic performance of multiple induction motors (IMs) in microgrids instead of a single motor with the same rating under a wide range of operating conditions are looked at. A single microgrid and an interconnected microgrid are two alternative model configurations designed in Matlab/Simulink that are considered in this study’s comparison of non-linear dynamic simulations. The findings show that, compared to a local microgrid system, the performance of an interconnected microgrid system is more susceptible to being impacted by several parallel IM loads. Furthermore, it has been discovered that large IMs have lower LFO damping capabilities than parallel multiple small IMs.
