1. A method for effectively utilizing energy storage components within a microgrid, the method comprising:

  • connecting a first plurality of energy storage components to a DC bus through switches;

    connecting a second plurality of energy storage components to an AC bus through inverters;

    connecting controllers to the energy storage components, the controllers having a state of charge and a state of health algorithm adapted to measure the state of charge and the state of health of the energy storage components under dynamic charge or discharge conditions;

    connecting a first plurality of the controllers to the DC bus to regulate bidirectional flow of energy between the DC bus and the first plurality of energy storage components;

    connecting a second plurality of the controllers to the AC bus to regulate bidirectional flow of energy between the AC bus and the second plurality of energy storage components;

    interconnecting the controllers with a local energy storage system bus; and

    controlling the controllers via a master microgrid controller connected to the local energy storage system bus.
