ESS METHOD DEVICE AND SYSTEM FOR PROVIDING CHARGING POWER USING ESS FOR POWER SUPPLY OF POST TYPE ELECTRIC DEVICE

摘要

According to one embodiment, in a method of supplying and providing power to enable a charging service using an ESS (Energy Storage System) for power supply of a pole-type electric device, performed by a control device, at a preset lighting time of a street lamp Accordingly, when it is determined that operation of the plurality of post-type electric devices is necessary, power is supplied to each of the plurality of post-type electric devices from the power system, and the lighting installed in each of the plurality of post-type electric devices is controlled to turn on, measuring a lighting load through the amount of power used for the lighting; When it is confirmed that the charging plug installed in each of the plurality of post-type electric devices and one or more electric vehicles are connected, power is additionally supplied from the power system to the electric vehicle, and the battery of the electric vehicle is controlled to be charged, and measuring a charging load through the amount of power used as a charging service for the electric vehicle; When it is confirmed that the total load, which is the sum of the lighting load and the charging load, is less than the available supply capacity of the power system, the state of the ESS connected to the plurality of post-type electric devices is maintained in standby mode and stored in the ESS. controlling the power not to be discharged; and controlling the power stored in the ESS to be supplied to the plurality of post-type electric devices by setting the ESS to a discharging mode when it is confirmed that the total load is greater than the available supply capacity. A method of providing charging power using an ESS for power supply is provided.
