Dynamic intelligent load balancing in power distribution networks

•We present an algorithm for dynamic intelligent load balancing (DILB) in a PDN.•The algorithm is heuristic, generic, recursive, fast and applicable in a real PDN.•We improve the overall load balance in a PDN and minimize active power losses.•We test the algorithm on existing PDN models and address the achieved improvement.

Using hierarchical, client–server addressing concepts and identifying the load balancing problem among phases in 3-phase systems, we propose a novel, very simple algorithm for dynamic intelligent load balancing (DILB), that decreases the power losses in a power distribution network (PDN). Our solution is easily applicable to every part of a PDN, without essential changes to the last-line power installation. We present the DILB-extended PDN architecture, the algorithm itself as well as the results of the simulation on the well known IEEE 34-Bus, 37-Bus and 123-Bus networks that confirm the expected level of active power losses minimization.
