Özet

The increasing penetration of renewable energy sources and flexible loads, such as electric vehicles, is reshaping the operational strategies of distribution system operators (DSOs). To address these rapid and dynamic changes, DSOs must adopt innovative methods for maintaining system stability and efficiency. This paper introduces an analytical approach for managing overloaded lines in ring-operated power distribution systems by optimizing the operation of flexible loads and generation units. The method leverages a sensitivity matrix derived from the system topology to determine optimal set points for flexible resources, ensuring that branch currents are adjusted to achieve desired operational outcomes. Simulation results highlight the effectiveness of the proposed method in enhancing system performance under dynamic conditions.
