Development of 20kW energy storage system for Smart Green Town

The main purpose of this paper is to introduce the development and structure of 20kW Energy Storage System (ESS). The basis of the capacity selection of 20kW ESS, which will be installed in ‘Se-hwa sanatorium’, is introduced. The Smart Green Town is defined and its structure is also introduced in this paper. The possibility of success with this system will be verified as an ESS through the simulated results of the grid-connected mode and the stand-alone mode.
