The Value of Intra-Day Markets in Power Systems With High Wind Power Penetration

In this paper, the value of intra-day markets in managing wind power uncertainty in competitive electricity markets is analyzed. A competitive electricity market model consisting of a day-ahead market and a number of intra-day markets is considered. Real-time operation adjustment is also taken into account. Stochastic programming is used to model decision making under wind power uncertainty. Numerical simulations based on two test systems are presented.
