Abstract
A proportional-resonance (PR) controller along with virtual admittance compensator (VAC) is proposed in this paper for a grid-connected nine-level Packed E-Cell (PEC9) to enable zero steady state and transient errors for the controlled state variables. In order to present further detailed assessments, the closed-loop system of the proposed control strategy is attained to analyze the effects of the coefficients of PR controller as well as the VAC coefficient under various operating conditions. The grid-connected PEC9 is simulated by Matlab/Simulink environment under load variation to verify the validity of the proposed control strategy.
