Maximum Loadability Limit of a Power System Using Multiagent-based Hybrid Particle Swarm Optimization

Abstract

Estimating the maximum loadability limit of power systems is one of the approaches to voltage stability. The maximum loadability limit is the margin between the operating point of the system and the maximum loading point that can be formulated as an optimization problem. This article utilizes the newly developed multiagent-based hybrid particle swarm optimization method for solving this problem. Details of the implementation of the proposed method to two test systems (IEEE 30-bus and IEEE 118-bus) are presented. Simulation results show that the proposed approach converges to a better solution much faster, which proves the loadability and applicability of the proposed method.
