Abstract
The invention discloses a multi-port flexible AC interconnection device with active power flow control capability for an AC power grid, including a static synchronous compensator and a multi-port flexible interconnection module connected in series. The multi-port flexible interconnection module includes multiple voltage-source single-phase inverters sharing a DC bus, and each port is connected to a different AC power grid feeder line. By adjusting the amplitude and phase of the AC output voltage of the single-phase inverters connected in series on the feeder line, flexible interaction of active power between the feeder lines is realized, and decoupled control of active and reactive power on the feeder lines is achieved. By introducing the multi-port flexible interconnection module, the invention provides multiple controllable AC ports connected to multiple feeder lines, realizing flexible interconnection between the feeder lines, i.e., flexible interaction of active power between the feeder lines and achieving active control of power flow between the feeder lines, which can realize a flexible AC power grid with multi-port interconnection while providing corresponding reactive power to each feeder line.
