Title:
ENERGY STORAGE POWER SUPPLY SYSTEM AND ENERGY STORAGE POWER SUPPLY BOX
Document Type and Number:
WIPO Patent Application WO/2020/248415
Kind Code:
A1
Abstract:
An energy storage power supply system, comprising: an energy storage apparatus (10), an energy storage management apparatus (20), a two-way current inversion apparatus (30), an energy storage monitoring terminal (40), and an energy storage monitoring back-end device (50) disposed at a power grid control center. The energy storage apparatus (10) is electrically connected to a direct-current end of the two-way current inversion apparatus (30), an alternating-current end of the two-way current inversion apparatus (30) is used for accessing the power grid, the energy storage apparatus (10) and the energy storage management apparatus (20) are electrically connected, and the energy storage monitoring terminal (40) is in communication connection with the energy storage management apparatus (20), the two-way current inversion apparatus (30), and the energy storage monitoring back-end device (50), respectively. Energy storage state information and current inversion state information are reported by means of the energy storage management apparatus (20) and the two-way current inversion apparatus (30), and the energy storage monitoring terminal (40) and the energy storage monitoring back-end device (50) determine charging or discharging demand in real time to control the energy storage device (10) to charge or discharge. When the power grid has a high load, extra electric energy may be steadily supplied to the power grid to ensure power supply and safe running of the power grid; and when the power grid has a low load, charging is automatically performed to complete reservation of electric energy and make full use of the surplus power of the power grid, which is energy-saving, environmentally-friendly, stable, and reliable.
