“…The performances of the fundamental VSR or CSR are modified by the quasi‐Z‐source circuit. To meet requirements of more demanding grid codes [28], AC–DC converters in wind applications have to employ more advanced controllers [6, 8, 13]. This in turn requires accurate models of wind energy conversion systems including those for the converter to be derived [2, 4, 12, 19].…”

“…In wind energy applications, AC–DC converters interface the generator to a DC link or DC transmission [4] while AC–DC–AC converters are used to interface generators to an AC system [5–7]. Moreover, AC–DC converters with suitable controllers are employed in wind energy conversion systems and other applications to accomplish tasks that include, but not restricted: voltage and frequency control [3, 8–10], harmonic mitigation and power quality support [2, 11, 12], fault‐ride‐through and voltage support during faults [3, 6, 8] as well as variable speed operation of generators [2, 4, 7, 13, 14]. Topologies previously used for active rectifiers have been mainly based on the conventional voltage source rectifier (VSR) and the current source rectifier (CSR) [1, 2, 4–7, 14–19].…”

Original scientific paper A fast excitation predictive control method for multi-machine power system is presented. The multi-step prediction technique is realized via system dynamic model. Some inequality constraints on states, inputs and outputs are considered in rolling optimization. The Gramian balanced reduction technique and the improved optimization algorithm are used in order to save the time of open-loop optimization in model predictive control. A 50machine power system is used to verify the effectiveness of this approach. Compared with simulated results under different controllers, this method can greatly reduce the calculating-time. The voltages of generator terminals are maintained within the set points. The stability of power system is improved.

Due to the intermittent nature of wind, the wind power output tends to be inconsistent, and hence maximum power point tracking (MPPT) is usually employed to optimize the power extracted from the wind resource at a wide range of wind speeds. This paper deals with the rotor speed control of a 2 MW direct-driven permanent magnet synchronous generator (PMSG) to achieve MPPT. The proportional-integral (PI), proportional-derivative (PD), and proportional-integral-derivative (PID) controllers have widely been employed in MPPT studies owing to their simple structure and simple design procedure. However, there are a number of shortcomings associated with these controllers; the trial-and-error design procedure used to determine the P, I, and D gains presents a possibility for poorly tuned controller gains, which reduces the accuracy and the dynamic performance of the entire control system. Moreover, these controllers' linear nature, constricted operating range, and their sensitivity to changes in machine parameters make them ineffective when applied to nonlinear and uncertain systems. On the other hand, phase-lag compensators are associated with a design procedure that is well defined from fundamental principles as opposed to the aforementioned trialand-error design procedure. This makes the latter controller type more accurate, although it is not well developed yet, and hence it is the focus of this paper. The simulation results demonstrated the effectiveness of the proposed MPPT controller.
