Abstract

In this paper, a high-performance grid simulator based on parallel structure fractional repetitive control scheme is employed to emulate various operation scenarios of power grids for testing power products. In this paper, a simple fractional repetitive control scheme is proposed for grid simulators to achieve high-accuracy tracking performance. Using parallel branches, the proposed repetitive controller can flexibly select the interested harmonics for compensation, and independently tune the convergency rate at selective harmonic frequencies. Compared with conventional repetitive control, the proposed control scheme achieves faster transient response. Moreover, the number of delay units required in the proposed repetitive controller is reduced to at least half of that in conventional repetitive controller. Design process and stability criteria are presented in details. A set of experimental results is provided to verify the effectiveness of the proposed approach.
