1. A method for operating a power system having a central control unit and a first power system component and a second power system component, the method comprising:
determining a first self-estimated value of the first power system component in an associated control unit based on a first state value;
ascertaining a second self-estimated value of the second power system component in an associated control unit based on a second state value,
wherein each power system component includes a control unit connected to the central control unit;
providing the central control unit with a present maximum amount of power for each of the first power system component and the second power system component;
receiving a request for a demanded electrical power in the central control unit;
ascertaining in the central control unit a distribution variable relating to the demanded power for each power system component based on the respective self-estimated values and the respective maximum amount of power output,
wherein the distribution variable comprises a weighting variable as the quotient of the self-estimated value and the maximum power of a power system component in relation to the sum of all the self-estimated values and the respective maximum power thereof; and
distributing a demanded electrical power to the power system components,
wherein the power system components comprise an energy generator unit, an energy consumer unit, or an energy storage unit.
