Voltage Feedforward Control with Time-Delay Compensation for Grid-Connected Converters

In grid-connected converter control, grid voltage feedforward is usually introduced to suppress the influence of the grid voltage distortion on the converter’s grid-side AC current. However, Owing to the time-delay in the control system, the suppression effect of grid voltage distortion is seriously affected. In this paper, the positive effects of the grid voltage feedforward control are analyz...

A Generalized-Impedance Based Stability Criterion for Three-Phase Grid-Connected Voltage Source Converters

1  Abstract—The output impedance matrices of three-phase grid-connected voltage source converters (VSCs) are widely used in power system stability analysis. Regardless of how the impedance is modeled, there always exist coupling terms in the impedance matrix, which makes the system a multi-input-multi-output (MIMO) system. As a practical approximation, the coupling terms are generally omitted ...

Design of a Digital Voltage Controller in Single-Phase Grid-Connected Renewable Converters

Power decoupling of pulsating grid side power from constant source side power is one of the paramount issues in single phase-phase grid-connected renewable systems. The principal aim of such systems is the decrease of the capacitance of the decoupled capacitor. However, this causes some problems such as an increase in the total harmonic distortion (THD) of injected current to the grid and bus v...

Generalized-impedance and Stability Criterion for Grid-connected Converters

The output impedance matrix of a grid-connected converter plays an important role in analyzing system stability. Due to the dynamics of the DC-link control and the phase locked loop (PLL), the output impedance matrices of the converter and grid are difficult to be diagonally decoupled simultaneously, neither in the dq domain nor in the phase domain. It weakens the effectiveness of impedance-bas...

Modeling and Control of Voltage Source Converters Connected to the Grid

This thesis deals with the modeling and control of pulse width modulated (PWM) voltage source converters connected to the grid. When voltage source converters are connected to the grid, the power quality and the dynamic performance are affected by the line filter connected between the converter and the grid, and by nonlinearities caused by the switching converter. In the thesis, the dynamic per...
