최소 출력 제약을 위한 재생에너지 발전 비율 산정

Abstract

The renewable energy resources have been attracting public attention because of environment problems like global warming effect. Although the renewable energy has been constructed rapidly over the world, this uncontrolled power sources can cause a problem of grid stability such as unbalance situation between electricity supplement and demand load. Especially, variability of renewable energy can negatively affect to power system and increasing penetration of renewable energy causes penetration limit of renewable energy. The grid operator has curtailed renewable energy to maintain stable grid conditions. From this view point, this thesis is analyzed for wind and solar power generation ratios comparing with power load to minimize the limitation of grid connection clean energy. Also, it presents curtailed renewable energy depending on the ratio between wind and solar power generation. In addition, the application of energy storage system devices was also considered to maximize the use of renewable energy.
