Title:
CONTROL METHOD FOR NEW ENERGY MICRO-GRID ELECTRIC VEHICLE CHARGING STATION
Document Type and Number:
WIPO Patent Application WO/2018/103232
Kind Code:
A1
Abstract:
Disclosed is a control method for a new energy micro-grid electric vehicle charging station, for use in active power control operation in a networked mode: detecting operating parameters; determining whether the load power capacity detected in real time reaches a maximum allowable power capacity, and it yes, starting an energy storage module to increase the discharge power of the energy storage module or reduce a load; determining whether the main voltage of a low-voltage main busbar reaches an upper limit voltage value, and it yes, reducing the discharge power of the energy storage module if the energy storage module is discharging; if the energy storage module is not in a discharge state, suppressing a distributed new energy power generation unit; and determining whether the main voltage of the low-voltage main busbar reaches a lower limit voltage value, and if yes, starting the energy storage module to increase the discharge power of the energy storage module or reduce the load. The control method implements stable and efficient control.
