It is expected that renewable power will increase uncertainty to the overall power supply system because renewable power generation depends on the volatility of external conditions of renewable resource. Future supply of renewable power will be increasing due to active government promotion of renewable energy utilization.We investigate the impact of renewable power generation on the peak time electricity supply deriving the representative wind mill and its power curve. Simulation result shows that peak time impact of renewable power generation on the electricity supply may reach the maximum of 1.328GW by year 2011, 2.308GW by year 2017, respectively. This implies that the concept on the size of deterministic power capacity will have difficulty understanding the volatile nature of renewable power production and this type of probabilistic approach of analysis may provide an alternative to that.
