Abstract: There is provided controllers, methods and systems to allocate power (current) for use in a hierarchical power distribution network. A power distribution method allocates power proportionally based on load demand for variable loads, such as EV charging, as aggregated from distribution points and any power reserve available to allocate for such points. The allocation is constrained in accordance with electrical constraints of each of the respective distribution points for safe allocation. Parent and child controllers are shown and described, with feature configurable in each for easy installation and start up. A publish/subscribe protocol provides automatic network establishment. Systems and methods are applicable to various topologies including those at residential complexes (townhouses), campus and major venues.
