SCADA Network Topology

Autonomous Demand Area Power System (ADAPS)

• Loop Power Flow Controller (LPC)• Demand Supply Interface (DSIF).

SCADA SYSTEM FOR THE ADAPS

• Control Devices.• Mobile Agents. • Wide-area Ethernet.

Control devices in the ADAPS

Mobile agents used in the SCADA system for ADAPS

Configuration of a wide-area Ethernet following our design policy

MAIN FEATURES OF THE FAULT-TOLERANT PROTOCOL FOR AGENT MIGRATION

Procedure of the best-effort agent for migration.

Procedure for sending an agent according to the iterative transmission protocol.

Procedure for receiving an agent according to the iterative transmission protocol.
