Abstract
In this paper, we propose a simplified voltage regulation strategy to mitigate voltage issues in active distribution grids with high penetration of flexible resources. This approach is based on the assumption that voltage levels may exceed permissible limits at nodes where flexible resources are connected, particularly when local generation exceeds local demand. To address these abnormal voltage conditions, the proposed strategy incorporates a data-driven system identification technique combined with an optimization-based control framework. This facilitates the assessment of the method's effectiveness under operational scenarios that realistically capture the variability and uncertainty inherent in modern distribution systems. The proposed approach was tested on the real distribution network of Pereira-City, using time-series simulations with realistic generation and load profiles, demonstrating effective voltage regulation and improved grid performance. Special emphasis was given to the computational time, which was significantly reduced compared to conventional voltage regulation approaches, highlighting the method's potential for practical implementation.
