Method for adjusting distributed energy generation system and distributed energy generation system

摘要

The present invention relates to a method of adjusting a distributed energy generation system having a plurality of inverters (in) determined by operating a central control unit (PPC) to a grid (2).The central control unit (PPC) detects the effective power, reactive power, and voltage amplitude at the grid connection point (PCC) of the energy generation system (1).In the normal operation mode of the energy generation system (1), the central control unit (PPC) splits the target value designated by the central control unit (PPC) into individual target settings of the plurality of inverters (in); The reactive power and the effective power are adjusted to the target value specified by the grid operator in that the individual target setting is communicated to the inverter (in).The switching of the energy generating system to a particular operating mode involves three following criteria: the reduction of the voltage amplitude beyond the designated first threshold, the increase in the effective power beyond the designated second threshold, and the reactive power change that does not exceed the designated third threshold in the insufficient excitation direction If executed at a grid connection point (PCC) at a specified time interval is executed.In a particular operating mode, the central control unit (PPC) reduces the effective power provided at the grid connection point (PCC) relative to the designated target value.The present invention also relates to a distributed energy generating system (1).Diagram
