Dynamic setting method for active power droop coefficient of distributed power supply controller

The invention discloses a distributed power supply controller active power droop coefficient dynamic setting method comprising the following steps: determining distributed power supplies in an area, and collecting rated active power Pi, e of all distributed power supplies; establishing a historical data set; performing data cleaning on the historical data set, and constructing an optimized data set; establishing an active power droop coefficient calculation model by using a support vector machine and carrying out training regression; whether power oscillation occurs is judged, if power oscillation occurs, the active power droop coefficient mi is set to be 0, the distributed energy power maintains the original power generation power, and droop characteristic adjustment is not carried out. According to the method, multiple existing simulation technologies are applied on site, actual operation parameters are collected and analyzed, data with a good effect are selected to carry out training iterative optimization
