Implementation of mandatory ESS installation policy in Korea
Rational Energy Use Act prepared based on Article 8 and Article 15 of the Enforcement Decree of the same Act,
In accordance with Article 11 (5) of the 『Regulations on Rationalization of Public Institutions’ Energy Use』, public institutions Buildings with a contracted power of 1,000Kw or more are subject to the mandatory installation of an energy storage system (ESS) with a scale of 5% or more of the contracted power.
In accordance with Article 2, Paragraph 3 of the Addendum of the 『Regulations on Rationalization of Public Institutions’ Energy Use』, new buildings 2017.1.1 (based on the building permit application date), installation of existing buildings must be completed by 2023.12.31.
ESS Configuration
BMS (Battery Management System)
Store (charge) the electrical energy received from the grid and output (discharge) the stored electrical energy to the grid
Overcharge, over discharge, overcurrent protection function by sensing the voltage, temperature, and current of the battery
PCS (Power Conversion System)
PCS (Power Conversion System)
A power conversion system that converts the characteristics of electricity (DC↔AC, Voltage) to charge/ discharge the electricity stored in the ESS to the battery
PMS/EMS (ESS operation management system)
PMS (Power Management System)
EMS (Energy Management System)
ESS control by receiving information from PCS battery temperature and humidity sensors and peripheral devices (maximum power demand controller, relay, charge/discharge meter, etc.)
