In this study, an adaptive capacitor switching algorithm is developed to optimize the use of switched capacitors as the availability and output of individual wind turbines change within wind farms. Wind farms are typically required to be able to operate within a power factor range of ± 0.
One traditional approach to a capacitor control scheme would find fixed open and closed thresholds for the capacitors, an approach that does not adapt to changes in the wind farm.
As shown, wind turbine and ultra-capacitor system are connected to a microgrid with a weak network. This microgrid is severely reacting against power fluctuations and transferred energy. Based on this, controlling power and output energy of wind turbine in this condition is of high importance.
Wind farms are typically required to be able to operate within a power factor of +/- 0.95. In order to achieve this range of operation, switched capacitor banks are used to supply bulk reactive power to the system when the generators approach their reactive power limits.

Therefore, capacitor banks are used to compensate reactive power, which in turn improves the voltage profile of the network. Although capacitor banks help improving voltage profile, they also undergo switching actions due to its compensating response to the variation of various types of load at the consumer's end.
Increase in wind speed and as a consequence, increase in wind turbine produced power puts the ultra-capacitor in charge mode which is obviously observable in the voltage of ultra-capacitor. Continuation of charging makes the ultra-capacitor to reach its charging limitation at 4.55 s.
Although capacitor banks help improving voltage profile, they also undergo switching actions due to its compensating response to the variation of various types of load at the consumer's end. These switching activities could cause transient overvoltage on the network, jeopardizing the end-life of other equipment on the system.
