Business Introduction

Energy Storage System
Essential system for improving energy efficiency and stable supply of new and renewable energy
The energy storage system is the system which stores and supplies the produced energy at the time when energy is required to improve energy efficiency. It can be utilized in the power system such as development, power transmission and distribution, and customers (buildings & plants). Also, the system solves the power quality problem which is one of the disadvantages in new and renewable energy to enable stable energy supply.

ESS system configuration

ESS (Energy Storage System) consists of Battery / BMS (Battery Management System) / PCS (Power Conditioning System) /EMS (Energy Management System) and other power distribution and communication facilities.

  • ESS configuration
    Battery/BMS + PCS (Power Conditioning System) + EMS + protection system, etc
ESS configuration
  • Battery : Perform charging and discharging of Grid/new and renewable energy generation
  • BMS : Perform the whole monitoring function of battery system (voltage/electic current/SoC/SoH/temperature)
  • PCS : Inter-conversion control between KEPCO (Grid)/new and renewable energy generation (AC) and battery DC power
  • PMS : Perform overall ESS monitoring including collection and monitoring of battery and PCS operation information and environmental facilities
  • EMS/SCADA : Perform energy management function of (x)EMS or IBS system in buildings and plants and overall energy management (predictive operation, evaluation and external system interlocking)
