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: |

-Multi-terminal DC (MTDC) power transmission
system is regarded as the optimal solution scheme to sent out
power from large-scale wind farm. A coordinated control
strategy for voltage source converter (VSC) based MTDC
transmission system applied to long-distance power
transmission from large-scale wind farm is researched. By
means of constructing a four-terminal system connecting two
large-scale wind power bases with local power grid to send out
power to faraway load center, the wind power converging and
sending out by the proposed coordinated control strategy are
implemented. Simulation results show that the proposed
coordinated control strategy not only can improve the ability of
reallocating power flow in VSC-MTDC transmission system
under large disturbance, but also can make wind power base
providing a certain power support to DC transmission network,
thus the dynamic stability of power grid can be enhanced.

Description: s a clean renewable energy, wind energy draws more
and more attention around the world. In case of high wind speed
or low speed but substantial installed wind power capacity, wind
turbine generators (WTGs) will take the place of traditional
power plant partly. Under the circumstance, the transient
stability will change. Therefore, in this article, the synthetical
dynamic model of WTG is introduced first, and on the basis of it,
the article focus on the comparison of transient stability

Description: This study presents wind turbine converter stability analysis of wind farms in frequency domain. The interaction
between the wind turbine control system and the wind farm structure in wind farms is deeply investigated. Two wind farms
(i.e. Horns Rev II and Karnice) are taken into consideration in this study. It is shown that wind farm components, such as
long high-voltage alternating current cables and park transformers, can introduce significant low-frequency series resonances
seen from the wind turbine terminals that can affect wind turbine control system operation and overall wind farm stability Platform: |
