| Abstract: |
DC microgrids have become essential topology with applying of the renewable energy resources in the today distribution systems especially where there is a permanent problem about power quality۔ In this paper, the design parameters of a DC microgrid are explored, focusing on strategies to enhance power quality such as voltage stabilization, harmonic reduction, ripple suppression, and also enhanced droop control techniques. Within this context, a simulation-based comparative approach is adopted, using validated data from the published experimental and/or simulation studies conducted in the years 2021 to 2025. This study presents the hypothesis that utilizing a well-established droop control with hierarchical energy management will achieve marked improvements in terms of voltage deviation and total harmonic distortion (THD) in voltage signals generated in a configurable DC microgrid. Results validate that DC microgrids with optimal control meet the requirement of voltage deviations below ±2%, THD of less than 3.5% and the path to the efficiency improvement of the system is high as 94.3% compared with the comparable AC case. In the discussion, the results are compared with certain IEEE and MDPI literature, and the importance of layered control strategies remains significant for reliable power delivery. The common study and findings of active power quality mechanisms applied to DC microgrids has presented a superior characteristic of sustainable electrification suitable for ever-changing energy infrastructure of India. |
