PO093: Ambient-aware day-ahead security analysis for reducing wind generation curtailment
Danka Veljkovic, Senior Power System Engineer, Electricity Coordinating Center
Abstract
Integration of wind energy into power systems is often limited by transmission network constraints, particularly line capacity. Traditional day-ahead security analysis relies on static line ratings, which do not fully capture the effects of ambient conditions on line capacity or the uncertainty of wind generation forecasts. Contingencies carry different levels of risk and impact on system security, and treating them all equally, especially in the day-ahead horizon, can lead to overly conservative operational decisions. This paper presents a novel classification algorithm that dynamically assesses overloads under forecasted ambient conditions, considering the time to reach the maximum allowable conductor temperature, and enables the identification of critical network elements. Based on this analysis, the algorithm minimizes total unproduced energy from RES over the day-ahead horizon. The approach introduces flexibility into day-ahead security analysis without compromising N-1 compliance, allowing differentiated treatment of contingencies. By leveraging the thermal inertia of system elements, it enables better utilization of available wind energy while maintaining system security.. The methodology is tested on the Serbian transmission system, including regions with high wind penetration. Day-ahead contingency analyses are simulated with and without the proposed ambient-aware approach. Results demonstrate significant reductions in wind curtailment, improved operational flexibility, and increased renewable energy sources (RES) integration. The findings highlight the potential of this method to support higher RES penetration and more resilient, efficient power system operation, contributing to Serbia’s decarbonization objectives.
