Abstract

This chapter presents new explorations into the use of agent technology applied to the protection of power systems. We broadly define an agent to be an autonomous piece of software capable of interacting with its environment. Our investigation centers on the use of agents within an electric power grid using a private communication network, termed a Utility Intranet, based on Internet technology. Our goal is to create practical agents that can be examined in realistic situations. To facilitate this aim, a new platform has been developed, EPOCHS, which allows agents to operate in an environment that combines proven electric power electromagnetic and electromechanical transient simulators with a popular network communication simulation engine. We have developed a remote load shedding scheme, a back-up protection system and a differential protection method using agent technology and evaluated each case within the EPOCHS environment. Agent-based systems improve on traditional methods in each case. Results illustrating the performance and viability of agent-based protection system are presented.
