Agent based distributed optimal power flow using ADMM method

Abstract

In this paper, we address the AC optimal power flow (OPF) problem of a microgrid with a distributed mathematical strategy. The goal is to find an optimal operating point of a grid with limited communications. A multi-agent system was designed to implement a state-ofthe-art distributed optimization method, which is alternating direction method of multiplier (ADMM). An agent, hosted in a processor installed at grid nodes, sends optimal set points to connected controllable devices. In this distributed strategy, agents need only local and neighbourhood data but can give global solutions. A 6 bus system is used to validate the agent based distributed algorithm with 6 agents at locations of nodes.
