Abstract

In power systems, reserves are essential to ensure system security, certainly when challenges of predictability (inaccurate forecast) and variability (imperfect correlation of renewable generation and system load) are causing power imbalances. Different techniques can be used to size and allocate reserves for power imbalances from wind and solar power generation. In this work, the Hilbert-Huang decomposition technique is used to propose the deployment of different types of reserves. Here, the novel approach is to deploy automatically-activated reserves mainly for capacity related imbalances whereas manually-activated reserves are recommended to be deployed for energy related imbalances. The results show that imbalances due to predictability inaccuracy for both wind and solar power are certainly energy restricted and manually activated reserves could be deployed. In terms of variability-consequences, wind power generation does not change the average demand for reserves. Contrarily, solar power generation influences the deployment of upward and downward reserves at off-ramping periods in-between morning and evening.
