Improved DC-Link Voltage Regulation Strategy for Grid-Connected Converters
Objective
Main objective of this project is, fast transient response, regulate the dc-link voltage, reduce harmonic oscillations at the dc-side caused by the unbalanced ac currents.
Abstract
In this project, an improved dc-link voltage regulation strategy is proposed for grid-connected converters applied in dc microgrids. For the inner loop of the grid connected converter, a voltage modulated direct power control is employed to obtain two second-order linear time invariant systems, which guarantees that the closed-loop system is globally exponentially stable.
For the outer loop, a sliding mode control strategy with a load current sensor is employed to maintain a constant dc-link voltage even in the presence of constant power loads at the dc-side, which adversely affect the system stability. Furthermore, an observer for the dc-link current is designed to remove the dc current sensor at the same time improving the reliability and decreasing the cost. The effectiveness of the proposed system is verified by simulation in MATLAB/SIMULINK.
Keywords: DC-link voltage, DC microgrids, second-order linear time invariant system, sliding mode control.
