Estimation of the proper capacity of Dispersed Storage and Generation system for uninterruptable service in one bank outage case in 154/22.9KV S/S

154/22.9 KV S/S의 1 BANK 사고시 무정전 전력공급을 위한 분산형 전원의 적정용량 산정 검토

Over the last decade or so, there has been an increase in activity devoted to the development of renewable resources for generating electric energy. Many of these generators are small and can only be economically connected to the distribution system or to ths subtransmission system. Those which involve storage, a secondary source of energy, can provide a means to achieve more efficient use of existing generating plant. Such systems are known collectively as Dispersed Storage and Generation devices, or DSGs. So, in this paper, for uninterruptable service in one bank outage in 154/22.9KV substation, the proper capacity of DSGs is examined through the configuration and the reliability.
