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 ESS battery capacity and PCS capacity, an input unit for receiving rate information and power consumption data, a memory in which information on a plurality of preset power conditioning system (PCS) capacity is stored, PCS capacity and ESS (Energy) Storage System) When a capacity is set, a scheduling unit that generates a charge/discharge schedule of an ESS battery according to the rate information and a preset PCS capacity based on a preset rule, and based on the rate information, the ESS according to the charge/discharge schedule Of the ESS battery capacity corresponding to each of the plurality of PCS capacity, and a cost calculation unit for calculating the cost according to the set PCS capacity and ESS capacity, and a gain calculation unit for calculating the annual gain generated during charging and discharging of the battery Determining a combination, generating a charge/discharge schedule for each determined combination, calculate annual gains and costs corresponding to each of the combinations, and based on amounts subtracted from the annual gains for each combination based on preset conditions Characterized in that it comprises a control unit for extracting the matching capacity of the optimal PCS and ESS battery.
