Response of DSTATCOM under Voltage Flicker In Farm Wind

This paper presents the response of distribution static synchronous compensator (DSTATCOM). The connection of wind turbines to distribution systems may affect the voltage quality offered to the consumers. One of the factors contributing to this effect is the rapid variations of the wind turbine output power, which cause respective fluctuations in the supply voltage referred to as flicker. This paper presents the design, control and analysis of a DSTATCOM enhanced with an energy storage device when combined with a wind farm comprising fixed speed induction generators, In this paper it is shown that the DSTATCOM, controlled via a decoupled vector control technique, is an effective way of reducing voltage flicker emissions at the point of common coupling, removing the wind speed fluctuations and improving the transient stability of wind farm. Energy storage rating requirements are discussed in relation to the level of power quality obtained.
