Embodiment 1
[0048] A method for harmonic suppression of microgrid, such as figure 1 and image 3 ,include:
[0049] The harmonics of the microgrid are suppressed through the active control step, and if the harmonic content of the microgrid does not meet the standard conditions at this time, the harmonics of the microgrid are jointly suppressed through the active control step and the passive control step;
[0050] Among them, the active control steps include:
[0051] The microgrid harmonics are detected by the ip-iq method. According to the detected microgrid harmonics, the compensation current is generated through the grid-connected inverter using constant power control (PQ control), and the compensation current is combined with the grid-connected current required by the grid. As the reference current, the reference current is input into the grid through a grid-connected inverter based on PI control;
[0052]When the microgrid is connected to the grid, the inverter adopts simplified c...

[0074] An electronic device includes a memory and a processor, the memory stores a computer program, and the processor invokes the program instructions to execute the microgrid harmonic suppression method described in Embodiment 1.
Embodiment 3
[0076] A computer-readable storage medium, including a computer program, the computer program can be executed by a processor to implement the method for suppressing harmonics in a microgrid described in Embodiment 1.
[0077] Embodiment 1, Embodiment 2 and Embodiment 3 propose a microgrid harmonic suppression method, electronic equipment and computer media, and adopt a new strategy combining active control and passive control to improve the quality of the power grid. During the active control process, the inverter The control uses the improved ip-iq method to detect harmonics, adding a PI controller to make the harmonic detection process more stable and less affected by various loads and voltage imbalances. In the passive control process, UPQC is installed on the line, and the UPQC structure adopts SVPWM and PWM control methods are used as the control methods of the series side and the parallel side to compensate the distorted voltage and harmonic current, the control is simple...
