Establishment of ESS by customer type for optimal effect and Analysis of efficiency improvement of power system operation through installation of ESS

Abstract

Energy policy is shifting from supply to demand management, and the need for ESS is increasing due to the energy conversion policy centered on renewable and clean energy. As a result, ESS special fare plans have been introduced to encourage customers to voluntarily install ESS. In this paper, based on the results of ESS operation of each type of load of 127MWh battery installed by Kepco Energy Solution in 2017, we analyzed the effect of customer's business improvement and proper installation plan due to ESS special fare plan. In addition, we analyzed the effect of ESS installation on the customer load to improve the operation efficiency of power transmission and distribution system.
