In electric power distribution, a fractalgrid is a system-of-systems architecture of distributed energy resources or DERs.In a fractalgrid topology, multiple microgrids are strategically arranged to follow a fractal or recursive pattern. Fractals, or self-similar patterns, can be seen in nature. Clouds, river networks, and lightning bolts are a few examples of natural phenomena that display fractal features. In a fractalgrid, a microgrid may be composed of smaller microgrids or “fractal units”. In such a configuration, the network becomes one of simplified power flows and communications through distributed substations.
