“…The reactive control of DFIG and PMSG can quickly respond to voltage variation and make up for voltage variation due to wind speed fluctuation [24], [25]. However, the controllable reactive power of a wind farm is the sum of the reactive capacity of all VSWTs.…”

Wind speed fluctuations are extremely easy to cause the voltage change frequently. The existing voltage control methods are lacking in adjustment range and response speed. When wind speed fluctuates substantially or rapidly, voltage exceeding limit and the resulting grid safety problems cannot be avoided. Therefore, reasonably distributing and utilizing the reactive power of variable speed wind turbines in the whole network are an inevitable choice. However, the controllable reactive capacity of wind turbines is limited by converter capacity and active power, and thus, the grid demand may not be met. A new idea of active and reactive power-coordinated control for preventing voltage exceeding limit due to wind speed fluctuations was proposed. The effects of wind speed fluctuations on voltage were analyzed, and the controllable reactive capacity of variable speed wind turbines under wind speed fluctuations was studied. The relationship between voltage and the active and reactive power of wind farms was deduced. The theory and method of active and reactive power coordinated control before wind speed fluctuations were proposed based on the model predictive control theory. The control model based on multi-timescale was established. Finally, it was verified that the method can solve the voltage problems and maximize the system economy.

Summary Superconducting magnetic energy storage (SMES) units used along with wind farms are normally controlled with the aim of reducing the fluctuation in power injection to the grid due to wind speed variability. However, this paper proposes a modification of that control objective during system disturbances in order to reduce the accelerating power and improve stability margin. When the bus voltages get depressed due to short circuit fault in a nearby bus, the SMES is operated to draw additional active power from the system by means of modified control of the interfacing current sourced converter. Simultaneously, the grid side converter associated with the wind generator is operated to inject reactive power thus increasing bus voltage and power drawal by the SMES. This causes a reduction in the transient imbalance between electrical power and mechanical power of the nearby synchronous generators and thus enhances stability margin. In the post fault condition, the SMES and doubly fed induction generator active power outputs are controlled in such a fashion so as to improve further the transient stability of the overall power system. The study is carried in WSCC three‐machine nine‐bus system and IEEE 16‐machine 68‐bus system in PSCAD/EMTDC and MATLAB platforms.
