Agent Based Decentralized Three-Phase Load Flow Computation of Unbalanced Distribution System

Incessant network expansion, DG integration, system unbalances, growing solution complexity and increased communication saturation in distribution system have instigated the requirement of new solution methodologies for smooth and swift system analysis and operations. Hence, this paper proposes a fundamental framework on decentralized three phase load flow analysis of a distribution network. This framework is designed using Multi-Agent technology, wherein a single Bus Agent (BA) is designed. The objective of this BA is to compute the three phase voltages of its representative bus by utilizing the locally available information and inter agent communication. BA incorporate forward and backward sweep behaviors to compute bus voltages. The proposed framework is implemented in JAVA with JADE package and simulated on IEEE 34 node test feeder system with unbalanced loading conditions. The results showcase the validity and feasibility of the proposed decentralized system analysis.
