Application of a Methodology based on the Evolutionary Particle Swarm Optimization to Protection Coordination

Abstract

This paper describes the application of a discrete Evolutionary Particle Swarm Optimization-based (EPSO) methodology to a real case study network with high penetration of generation, for protection coordination. The high-resistance earth fault detection is based on the operation of a directional earth-fault overcurrent protection scheme with inverse time characteristic. The network is part of the HV Portuguese Distribution Network.
