풍력발전시스템 증가에 따른 제주 전력계통 특성 해석

Abstract

Recently, the renewable energies are being interested and developed to solve the shortage of fossil resources and the environmental problems. Comparatively speaking with fossil resources, the most of the renewable resources such as photovoltaic and fuel cell are economically poor as yet. However many of the wind power have been operated and come into wide use in EU. Based on the development of large capacity wind generator, the economic assesment of the wind power is highly valued. After all, now in these days, the large wind power is widely spread all over the world. It is accelerated to build the large capacity generator of the wind power. When the penetration of wind power is low, influences of the wind energy on the power system may be trivial. However when the penetration of wind enerage increases, its influence is not limited to the small network but starts to influence the whole system. According to wind power generation increase, the wind-generated power will constitue a noticeable percentage of the total electrical power demand consumed in Jeju. This indicates that the wind is becoming a major factor in electricity supply and in balancing consumer demand with power production. A major barrier to the integration of wind power into the grid is its variability. This paper presents the network operation characteristic analysis according to occupation of wind power generation and the influence analysis of Jeju power system connected with wind generation.
