This work is aimed at facilitating industrial adoption of agent technology. The paper proposes the hybrid agent architecture specific to the power system automation domain. The architecture builds on the Logical Node concept of IEC 61850 and comprises of a deliberative and a reactive layers; combining advantages of both. By relying on the underlined industrial standards IEC 61850 and IEC 61499, the architecture ensures practical applicability and captures domain specific concepts in the agent-based system design. Developed agentbased system was validated in the co-simulation framework. The architecture provides for rapid system development, reducing the software development life cycle. The benefits are in trace-ability of the software requirements, re-use of software components, ease of re-design, and direct deployment of the system model.
