A method for regulating a decentralized energy generating system with a plurality of inverters (IN) is disclosed. The method includes receiving at the PPC a detected active power, reactive power and voltage amplitude at a grid connection point (PCC) of the energy generating system; and regulating, in a normal operating mode of the energy generating system, the reactive power and the active power to target values stipulated by a grid operator by virtue of the central control unit (PPC) dividing the stipulated target values into individual target stipulations for the plurality of inverters (IN) and communicating individual target stipulations to the inverters (IN). The method further includes selectively changing to a special operating mode of the energy generating system if particular criteria are present at the grid connection point (PCC) in a stipulated time interval. In the special operating mode, the central control unit (PPC) effects a reduction of the active power provided at the grid connection point (PCC) compared to the stipulated target values.

A mobile working machine includes a working arm which is mounted in an articulated manner, by a first end, on a revolving superstructure of the working machine, and a tool which is mounted in a displaceable manner on a second end of the working arm. The mobile working machine includes a position control device of a working arm. At least one inclination sensor is arranged on the revolving superstructure and at least one inclination sensor is arranged on the working arm. Also, at least one rotation rate sensor is arranged on the working arm. The working machine further includes a calculation unit for processing the signals of the at least one inclination sensor, of at least one additional inclination sensor, and of at least one rotational rate sensor.
