DOI: ENHANCING RELIABILITY: OPTIMAL UNDERVOLTAGE LOAD SHEDDING IN A RESTRUCTURED POWER SYSTEM
Dipika Pandit , Department of Electrical Engineering, Jabalpur Engineering College, Jabalpur (M.P.), INDIAAbstract
In a restructured power system, maintaining system stability and reliability is of paramount importance. Undervoltage events can disrupt the stability of the system and lead to widespread power outages. This study focuses on the development of an optimal undervoltage load shedding strategy to enhance system reliability in a restructured power environment. By employing advanced optimization techniques, the research aims to identify critical load shedding patterns that mitigate undervoltage issues while minimizing the impact on consumers. The proposed approach considers network topology, load characteristics, and operational constraints, ensuring effective and targeted load shedding during critical conditions. The findings contribute to the effective management of undervoltage events in restructured power systems, bolstering system resilience and reliability.
