Distribution network operators face a number of challenges; capacity constrained networks, and balancing electricity demand with generation from intermittent renewable resources. Thus, there is an increasing need for scalable approaches to facilitate optimal dispatch in the distribution network. To this end, the authors cast the optimal dispatch problem as a decentralised agent-based coordination problem and formalise it as a DCOP. They show how this can be decomposed as a factor graph and solved in a decentralised manner using algorithms based on the generalised distributive law; in particular, the max-sum algorithm. They go on to show that max-sum applied naively in this setting performs a large number of redundant computations.
