Abstract: Objectives In order to enhance the stability of the controller and reduce the complexity of controller parameter tuning， an inverter feedforward control scheme with disturbance compensation for photovoltaic inverters was proposed.  Methods On the basis of maintaining the stable characteristics of feedforward control， the extended state observer （ESO） in active disturbance rejection control （ADRC） was used to estimate and compensate for the internal uncertainties and external disturbances of the controlled object， achieving disturbance reduction and enhancing the self-adjustment ability and disturbance resistance performance of feedforward control. A basic feedforward control variable was designed by using the characteristic that the inverter output expectation was a constant value， and send it to the standard system after disturbance removal was sent for control.  Results By inputting feedforward variables， the estimation burden of the observer can be reduced. Under the joint action of feedforward control and low bandwidth observer， good dynamic performance can be ensured while avoiding oscillation problems in the control system.  Conclusions The method proposed in this article can make the inverter output voltage stable and waveform smooth under estimation and compensation， and the control system can quickly respond to changes in the controlled object and external disturbances， demonstrating good transient characteristics and disturbance resistance. Finally， the effectiveness of the proposed control method was verified through MATLAB/Simulink simulation.
