1. A electrical power system, comprising:

  • a multiport power converter, comprising a plurality of electrical ports, each having at least two lines, and an energy transfer reactance comprising an inductor and a capacitor in parallel, wherein each line of each said port is connected to multiple ends of said energy transfer reactance through multiple respective bidirectional switches;

    a battery bank connected to a first one of said ports;

    an AC power source connected to a second one of said ports;

    a third one of said ports being connected to supply power to an AC power grid or microgrid;

    wherein said AC power source does not operate synchronously with the AC power grid or microgrid;

    wherein said converter draws power from said first, second, and/or third ports, and drives power into said first and/or third ports,while changing the frequency and/or phase of power received at said second port to thereby provide power synchronously to said third port when needed.
