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.
