a new power conversion system for megawatt pmsg wind turbines using four level converters and a simple control scheme based on two Step Model predictive strategy part ii simulation and experimental analysis
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2014Co-Authors: Venkata Yaramasu, Marco Rivera, Bin Wu, Jose RodriguezAbstract:A new power conversion system is explored in this paper aiming wind turbines rated at the megawatt level. The proposed configuration consists of a medium-voltage, permanent magnet synchronous generator connected to a low-cost three-phase diode bridge rectifier, a dc-dc four-level boost converter as the intermediate stage, and a four-level diode-clamped inverter on the grid-side. The dc-link capacitor voltages are balanced by the boost converter, and thus the control complexity for the grid-tied inverter is greatly simplified. To control the boost converter and grid-tied inverter, a simple method based on a two-Step Model predictive strategy is presented. In the first part of this paper, the continuous- and discrete-time Modeling of the proposed power conversion system is analyzed. The control objectives such as maximum power point tracking, dc-link capacitor voltages balancing, regulation of net dc-bus voltage, reactive power generation, lower switching frequency operation, and common-mode voltage minimization are considered in the design of controller.

Maximum power point tracking technique implementation of Z-source inverter through finite Step Model predictive control strategy
2012 7th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2012Co-Authors: Blaabjerg FredeAbstract:This paper presents techniques of maximum power point tracking (MPPT) implemented with finite Step Model predictive control (FSMPC) for the application of Z-source inverter. Incremental conductance MPPT algorithm and FSMPC Model is developed to control the output current of the grid-tied Z-source inverter in order to extract maximum solar power from the panel and then directly injecting the power into grid. The output current, passive component voltage and current are well regulated with proposed MPPT based FSMPC control strategy. Simulation of this proposed control algorithm is conducted in Matlab platform with PLECS toolbox. Both steady-state and transient results show that the high efficient and robust response of the proposed control technique.
