供給端予備力及び線路潮流感度を用いた電力流通設備更新計画の一手法

摘要

With the high economic growth era until 1990s, the power demand increased sharply year by year. Therefore, the electric power utilities installed many electric power facilities along with the predicted demand. However, in recent years, fewer infrastructures have been installed because electric power demand growth is saturated due to low economic growth. Therefore, in electric power facilities planning, it has been necessary to form a rational renewal planning which also considers social influence factors such as the construction quantity. In this paper, we propose a new transmission renewal planning method using Supply-end Reserves and Line Flow Sensitivities. We carry out simulations for the IEEJ EAST 10-machine -O/V model system and determine the transmission planning priority order to confirm the validity of the proposed method.%わが国の電力事業は，高度経済成長期からバブル期における高い電力需要の伸びに村応し，電力流通設備が大量に設置されてきた。従来の流通設備計画は，将来の需要想定に基づいて，需要増への対応を目的とした送電線や変圧器の新設・増設を行う拡充工事が主体となっていた。
