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 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 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 کاملImpedance Matching Based Control for the Resonance Damping of Microgrids with Multiple Grid Connected Converters
This paper presents an impedance-matching-based control scheme for the harmonic resonance damping of multiple grid-connected-converters (GCCs) with LCL filters. As indicated in this paper, harmonic resonance occurs if a GCC possesses an output impedance that is not matched with the rest of the network in some specific frequency bands. It is also revealed that the resonance frequency is associat...
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...
