A Generalized Class of Stationary Frame-Current Controllers for Grid-Connected AC–DC Converters
Within power systems, high-power pulsewidth-modulated ac–dc converters are used in flexible ac transmission systems controllers and for interfacing renewable energy sources to the grid. These converters traditionally employed PI controllers designed in the synchronous -frame with decoupling of and axes. Recently, stationary -frame proportional-resonant (PR) controllers have been proposed. Thoug...
متن کاملProportional-Resonant Controllers. A New Breed of Controllers Suitable for Grid-Connected Voltage-Source Converters
-This paper is describing the recently introduced proportional-resonant (PR) controllers and their suitability for grid-connected converters current control. It is shown that the known shortcomings associated with PI controllers like steady-state error for single-phase converters and the need of decoupling for three-phase converters can be alleviated. Additionally, selective harmonic compensati...
متن کاملGeneralized-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 کاملApplication 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...
متن کاملProportional-resonant controllers and filters for grid-connected voltage-source converters
The recently introduced proportional-resonant (PR) controllers and filters, and their suitability for current/voltage control of grid-connected converters, are described. Using the PR controllers, the converter reference tracking performance can be enhanced and previously known shortcomings associated with conventional PI controllers can be alleviated. These shortcomings include steady-state er...
