1. An inverter controlling method for a power system that includes a DC power source and a plurality of inverters connected in parallel to the power source, the method comprising the steps of:

  • measuring output power of the power source at a plurality of periodic points;

    calculating a moving average at each periodic point based on the measured output power;

    calculating a regression curve by utilizing moving averages at a current periodic point and past periodic points;

    estimating output power at a next periodic point based on the regression curve; and

    determining, based on the estimated output power, how many inverters to be actuated.
