This document summarizes a research paper that analyzes and designs a DC microgrid system for rural electrification in India. Key points:
1) The microgrid uses distributed solar PV generation, with maximum power point tracking converters connecting the solar panels. Fanout nodes distribute power to local clusters of homes, and power management units at each home regulate usage and integrate battery storage.
2) Experimental results from a 400W prototype demonstrate the steady-state operation and stability of the system when power from the solar source is varied. The microgrid is able to maintain a stable distributed voltage while enabling power sharing between components.
3) Calculations estimate the levelized cost of electricity for the microgrid design would be lower
