Method and device for regulating and controlling power flow of flexible distribution transformer

The invention discloses a method and a device for regulating and controlling the power flow of a flexible distribution transformer. The accurate regulation of the voltage and the power of each node in a power grid is realized. The node current and voltage signals are adjusted according to the tidal current power requirement, and the node voltage is maintained within a reasonable range while the power grid is kept to meet the power requirement, so that the operation state of the power grid is optimized. Wherein the load flow calculation model considers active and reactive power calculation formulas of primary and secondary side lines and active and reactive power calculation formulas of bus node injection. Accurate power flow regulation and control can be realized, and the stability and reliability of a power grid can be improved. Through real-time monitoring and accurate calculation of node current and voltage signals, the system can better evaluate the stability and reliability of the power grid, and provide
