AI Technical Summary
Traditional control methods for series active power filters involve complex control loops and difficult parameter tuning, making it difficult to effectively address grid voltage quality issues.
The traditional voltage and current dual closed-loop controller is replaced by deadbeat outer loop control and finite set model predictive control. The voltage to be compensated is extracted by detecting the power supply voltage of the distribution network, the output voltage is calculated and the current reference value is back-derived. The current prediction model in the αβ coordinate system is used to perform traversal optimization and select the voltage vector with the minimum value of the objective function as the inverter output voltage command.
It simplifies the control system structure, avoids cumbersome parameter tuning, realizes arbitrary harmonic compensation, reduces the computational burden of the digital controller, and improves the voltage quality compensation effect.
