APPARATUS FOR OPTIMIZING OF ESS(ENERGY STORAGE SYSTEM) AND PCS(POWER CONDITIONING SYSTEM) BATTERY CAPACITIES ESTIMATION AND CONTROL METHOD FOR THEREOF

摘要

The present invention relates to an ESS battery capacity and PCS capacity, an input unit for receiving rate information and power consumption data, a memory storing information on a plurality of preset PCS (Power Conditioning System) capacities, PCS capacity and ESS (Energy) capacity When the storage system capacity is set, the scheduling unit generates a charge/discharge schedule of the ESS battery according to the PCS capacity set based on the rate information and a preset rule, and based on the rate information, the ESS according to the charge/discharge schedule A gain calculator that calculates an annual gain generated during charging and discharging of the battery, a cost calculator that calculates a cost according to the set PCS capacity and ESS capacity, and a plurality of ESS battery capacities corresponding to each of the plurality of PCS capacities. A combination is determined, a charge/discharge schedule is generated according to each of the determined combinations, an annual gain and a cost corresponding to each of the combinations are calculated, and based on the amounts obtained by subtracting the cost from the annual gain for each combination, the predetermined condition is applied. It is characterized in that it includes a control unit for extracting the capacity combination of the optimal matching PCS and ESS battery.
