1. A framework for a multi-phase energy system comprising:
a plurality of modules arranged in a plurality of cabinets, wherein each module comprises a DC interface and an AC interface, and wherein each module comprises an energy source configured to output a DC voltage, a converter coupled with the energy source, and a local control device configured to control the converter to output a module voltage from the AC interface, the module voltage being selected from the group consisting of: a positive direct current (+DC) voltage, a reference output voltage, and a negative direct current (−DC) voltage,
wherein the plurality of modules are connected as a plurality of arrays such that each array is configured to output an AC signal having a different phase angle, wherein the modules within each array are connected as levels of that array such that the AC signal output by that array is a superposition of the module voltages from each module of that array, and
wherein each cabinet holds the modules belonging to at least one same level of the different arrays arranged along an axis orthogonal to a reference plane such that the modules of the at least one same level are aligned along the axis,
wherein, for at least two adjacent levels of the arrays, modules are arranged in order of array such that modules of the same array are aligned parallel to the reference plane at a same common distance from the reference plane,
wherein the DC interface of each module is electrically coupled to the DC interface of at least one other module via a first connector that is routed along a first side of the plurality of cabinets,
wherein the AC interface of each module is electrically coupled to the AC interface of at least one other module via a second connector that is routed along a second side of the plurality of cabinets, and
wherein, for each module of each array:
the first connector is an inter-level connector between two modules at different levels, and the second connector is an intra-level connector between two modules at a same level, or
the first connector is an intra-level connector between two modules at a same level and the second connector is an inter-level connector between two modules at different levels.
