1. A system for managing interactions between a plurality of devices selected from a group consisting of energy sources, energy loads and energy storage devices, the system comprising:

  • a control bus;

    a power bus;

    a plurality of energy device interfaces, each energy device interface comprising a control bus port, a power bus port and a device port, the device port for operatively connecting the energy device interface to a corresponding device selected from the group consisting of energy sources, energy loads and energy storage devices and for controlling the corresponding device, the energy device interface being operatively connected to the control bus via the control bus port and to the power bus via the power bus port,wherein each of the plurality of energy device interfaces comprises a dedicated power agent for operating the corresponding device, wherein each dedicated power agent directly manages low level physical details associated with operating the corresponding device such that each power agent provides a normalized power interface with the power bus;

    a power management unit operatively connected to the control bus and to the power bus, the power management unit configured to control each of the plurality of energy device interfaces according to a determined control strategy to thereby control interactions between the plurality of corresponding devices by controlling how and when each power agent interacts with the power bus at any time;

    wherein the low level physical details directly managed by any one of the dedicated power agents are not shared with the power management unit.
