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...
متن کاملDesign 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...
متن کاملA 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 ...
متن کاملInvestigation of the Effect of Synchronization Techniques on the Stability of Grid-Connected Photovoltaic Systems
Abstract: Due to the increasing use of microgrids, investigation of their stability is of special interest. One of the disadvantages of an inverter-based distribution unit is that at any given time, phase and frequency information at the point of common coupling (PCC) is required that affected the stability. The synchronization techniques include synchronous reference frame phase-locked loop (S...
متن کاملBifurcation Analysis of Three-Phase Grid-connected Converters
This thesis aims to identify and analyze the nonlinear behavior in the threephase voltage source converter, which is widely used as an interface converter in a distributed hybrid power system (DHPS). In this system, the converter does not work as a standalone converter but operates as a subsystem that connects to a non-ideal power grid and interacts indirectly with other subsystems via a point ...
