Backup of Electricity From Wind Power: Operational Backup Methods Analysed

The paper focuses on some methods for consideration of the backup requirements of wind power on the short term. The focus is therefore set on the operational backup. Insights are gained into the drivers of these backup requirements. Using a MILP approach, two methods are considered. The first method applies wind power backup through a 100% provision of additional spinning reserves. The second method relies on the balancing by Elia. Two sets of imbalance charge calculations are used. Both methods result in different additional charges that are being affected by the defined parameters.
