  "textContent": "The present invention discloses a system and control method of all-DC power supply and storage for a building. The system includes a renewable energy power generation apparatus, a mains grid system, a first DC/DC conversion apparatus, an AC/DC conversion apparatus, a first voltage DC bus, a first energy storage apparatus, and a first charge-discharge conversion apparatus. The first DC/DC conversion apparatus is configured to convert DC voltage generated by the renewable energy power generation apparatus to voltage of the first voltage DC bus. The AC/DC conversion apparatus is configured to convert AC power from the mains grid system to DC power. The first charge-discharge conversion apparatus is configured to control charge/discharge of the first energy storage apparatus. The first voltage DC bus is connected to a first electrical device and configured to power the first electrical device.",
