Finite-State Predictive Power Control based Interlink Converter for AC-DC Micro-grid

This paper present the finite-state predictive power control (FS-PPC) for the interlinking converter in the micro-grid. The proportional-integral (PI) based controllers are dynamically slower for the sudden changes in the power reference values. The phase lock loop (PLL) is essential requirement for such algorithms. The FS-PPC has faster dynamic response as compare to PI based controller in tracking the reference values. The FS-PPC is proposed to control the power flow between the DC and AC micro-grids. The developed control provides the constant switching frequency operation for the interlinking converter which reduces the ripples and total harmonic distortion of the grid current in order to follow the grid codes. Simulation results are provided for the validity of the control algorithm.
