Simplified Double-Loop Control Strategy Based on Energy-Fed Electronic Load
To improve the performance of the grid-connected inverter of the rear stage of the energy-fed electronic load on the premise of simplifying the control,the double-loop control system of the rear stage inverter of the system is improved.On the premise of replacing the control mode of the current inner loop,referring to the principle of universal deadlock,the relationship between the controlled param-eters of the voltage outer loop is compared by means of quasi-evolutionary game,which is simplified and optimized.The simulation re-sults show that compared with the original control,the controlled parameters are reduced from 4 to 2,the overshoot of the intermediate bus voltage is reduced by 29.8％,and the harmonic distortion rate of the grid-connected current is reduced by 25.3％,which can be sim-ply applied to the experiment.
