Title:
PHOTOVOLTAIC/ESS APPARATUS ENERGY MANAGEMENT SYSTEM FOR TRACKING POWER GENERATION REFERENCE, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/107632
Kind Code:
A1
Abstract:
The present invention relates to a photovoltaic/ESS apparatus energy management system for tracking a power generation reference, and a control method therefor, the energy management system creating profits of a power producer and improving the lifespan of a battery to be greater by charging an ESS and further proceeding with sales through the tracking of predicted power generation information in a state of producing and selling power from a photovoltaic/ESS, the energy management system comprising: a photovoltaic unit for generating electrical energy from the sunlight; a power conversion unit for converting the electrical energy generated by the photovoltaic unit into alternating current power and outputting the alternating current power; a PCS, which receives the alternating current power converted by the power conversion unit so as to convert the same into direct current power and output the direct current power; an ESS for receiving and storing the direct current power converted by the PCS; a Korea Electric Power Corporation system for buying the alternating current power converted by the power conversion unit or alternating current power converted through the PCS from the direct current power stored in the ESS; a load for receiving and using the alternating current power bought by the Korea Electric Power Corporation system; and an EMS, which receives power generation information of the photovoltaic unit, storage information of the ESS, and system information of the load so as to control the power of the power conversion unit and the PCS, thereby controlling the charging amount of the ESS, and controls the amount of power to be sold to the Korea Electric Power Corporation system.
