Description: High penetration of wind energy into the grid may introduce stability and power quality problems due to the fluctuating nature of the wind and the increasing complexity of the power system. By implementing advanced functionalities in power converters, it is possible to improve the performance of the wind farm and also to provide grid support, as it is required by the grid codes. One of the main compliance difficulties that can be found in such power plants are related to reactive power compensation and to keep the harmonics content within the allowed limits, even if the power of the WPP converters is increasing. This paper deals with an advanced control strategy design of a three-level converter performing STATCOM and Active Filter functionalities. A novel control strategy called Smart-STATCOM is introduced, since it has the capability of self-controlling reactive power and harmonic voltages at the same time. Platform: |

Description: 在传统反激变换器基础上，引入三电平技术，并针对传统反激三电平 DC-DC 变换器电源两端并联的分压电容不均
压的问题，提出了一种交错并联反激式三电平 DC-DC 变换器。该变换器具有电路拓扑简洁，输出只需电容滤波，减小输出滤波器，

three-level DC-DC converter to solve the capacitor voltage divider uneven pressure problems of traditional three-level flyback DC-DC
power converter. The converter has the advantages of simple topology, just capacitor filter output, reducing the output filter, improves
the converter power density, etc. This paper deeply analyzes the working principle and the work process of the converter, derive the

Description: This paper presents a nonlinear control scheme for back-to-back High Voltage Direct Current (HVDC) system based on feedback linearization control, using three-phase three-level voltage source converter. The design of the proposed nonlinear controller has been performed in a synchronous rotating reference frame (d-q) the aim to provide high dynamic performance, complete decouple control of active and reactive power and to maintain the DC bus voltage at its reference value.
The objective of maintaining balanced voltages in DC-link capacitors is achieved by using the three-level space vector modulation with balancing strategy based on the effective use of the redundant switching states of the converters voltage vectors. Finally, some simulations results are presented and discussed in order to verify and compared the feasibility and effectiveness of the proposed control scheme with the conventional controller (PI).
