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...

New method of current control for LCL-interfaced grid-connected three phase voltage source inverter

This paper presents an approach for the connection of a photovoltaic generator to the utility grid. A theoretical analysis, modelling, controlling and a simulation of a grid connected photovoltaic system using an output LCL filter are described in detail. In order to reduce the complexity of the system, a linear voltage and current controllers have been developed for a three phase grid connecte...

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...

Application of the Min-Projection and the Model Predictive Strategies for Current Control of Three-Phase Grid-Connected Converters: a Comparative Study

This paper provides a detailed comparative study concerning the performance of min-projection strategy (MPS) and model predictive control (MPC) systems to control the three-phase grid connected converters. To do so, first, the converter is modeled as a switched linear system. Then, the feasibility of the MPS technique is investigated and its stability criterion is derived as a lower limit on th...
