Abstract
Provided is an ESS charging/discharging schedule management device, and in particular, to an ESS charging/discharging schedule management device which maintains the charging/discharging efficiency of an energy storage device and minimizes an equalized discharge amount during a maximum load time period, thereby preventing a decrease in a customer baseline load which is a baseline for power demand response bidding.
Claims14
An energy storage system (ESS) charging/discharging schedule management device, comprising:
- a load amount data storage unit configured to provide information on a power load including a maximum load, a medium load, and a light load through statistical data on power consumption of a consumer by season and time period;
- a power control unit configured to control charging and discharging of an ESS by each time period of the maximum lead, the medium load, and the light load;
- a demand response (DR) participation capacity calculation unit configured to calculate a power demand response participation capacity in a total discharge capacity of the ESS;
- a scheduler configured to manage a customer baseline load (CBL) calculation period including the power consumption for a most recent five weekdays from a power demand response participation bidding date;
- and
- a CBL management unit configured to determine a discharge amount of the ESS so that the power demand response participation capacity is divided and discharged at different times on weekdays of a week managed by the scheduler;
- wherein the CBL management unit discharges the power demand response participation capacity at a time period of the maximum load, and
- sequentially performs discharging at a later time as each day passes after a first weekday when the discharge starts according to a power demand response discharge plan.

- and
- a load monitoring unit configured to monitor the power consumption of the power load,
- wherein the load monitoring unit calculates the power consumption used in the power load and compares the power consumption with baseline consumption determined as an abnormal working day to determine whether a corresponding day is the abnormal working day, and
- wherein the scheduler proceeds with a power demand response bidding when the power consumption of the power load is maintained at the baseline consumption or more of the abnormal working day, and recalculates the power demand response participation capacity when the power consumption of the power load is less than the baseline consumption of the abnormal working day.
