Capacity and Intra-Hour Ramp Reserves for Wind Integration

We propose a power-based unit commitment formulation with capacity and intra-hour ramp reserves for dealing wind power variability uncertainty. Although the has an hourly resolution, requirements capture excursions time duration below one hour, thus allows to consider intra-hourly This increases security of compared using more efficient scheduling units high rates. test different durations reserves, both find best reserve formulation. The formulations are evaluated 5-min economic dispatch, which simulates real-time operation system, hundreds out-of-sample realizations production. proposed then two stochastic resolution. outperform in terms security, showing that they provide is robust against variations. also total costs, giving better trade-off between costs security.
