Optimization of a 33-Bus Power Distribution System Using Artificial Hummingbird Algorithm for Power Loss and Voltage Stability Enhancement

Abstract

This paper presents an optimization study on the 33-bus power distribution system using a reconfiguration technique to enhance system performance. The optimization process employs two objective functions: minimizing active power losses and improving voltage stability through the reduction of the voltage stability index. The Artificial Hummingbird Algorithm (AHA), a novel metaheuristic approach, is adopted due to its efficiency in handling complex optimization problems. The proposed methodology is applied to both single-objective and multi-objective scenarios to comprehensively evaluate the system’s performance. Results demonstrate significant improvements in power loss reduction and voltage stability enhancement, underscoring the effectiveness of the AHA in optimizing reconfigured power distribution networks.
