An independent direct current (DC) grid power system on an isolated island is constructed, bringing together three wind turbines and one set of solar power installation. With different combinations of the new energy power generation devices in the DC grid, the 600 V DC busbar and network solution is verified successfully. This wind and solar energy DC grid system ensures a higher conversion efficiency, and helps to protect the stability of the new energy power system and increase the output power quality. Ultimately, the overall requirements of the project can be satisfied. This research can provide solutions to the future new energy multi-power systems.
