ESS Operations Planning, Economic Evaluation, and Commercialization Technology
We perform research on ESS modeling, on frequency regulation and renewable energy stabilization with ESS, and on the development and commercialization of core ESS technologies. Other R&D activities of the team include economic analysis and database construction, Biz model development and standardization, and Biz strategies for the expansion of ESS applications.
ESS Engineering Technology
We continuously develop our technical expertise in designing technical specifications, in designing ESS protection systems and power conditioning systems (PCS), and in providing consultation services for ESS installation and operation. In July 2015, the team completed a 28- and 24-MW grid-connected ESS demonstration project for frequency regulation at Shin-Yongin and Seo-Anseong substations.

ESS Operation Technology
We developed an ESS control and operation model for 52-MW frequency regulation ESS pilot project in 2015. Following its success, seven additional ESS facilities with a total capacity of 184MW were installed at 2016 and four additional ESS facilities with a total capacity of 140MW were installed at 2017. Currently, total 376MW ESS for the frequency regulation have been installed at 13 substations and is in commercial operation.
The team is committed in its efforts to develop ESS control and operation technologies such as the performance and safety evaluation and the status diagnosis of ESS facilities in order to operate ESS more efficiently and reliably during life of ESS facilities.
