“…It consists of a complex circuit of adder, subtracter, summer and multiplier. However, due to its memory effect, energy storage is mal-operated even though it does not show any significant output power fluctuation [98]. An energy capacitor system (ECS) is utilized to reduce the ramp-rate of variable wind power generators connected to the grid [97].…”

“…Moreover, a low pass filter is used to estimate the line power reference, which leads to enhanced system simplicity and cost effectiveness. The moving average (MA) method to generate line power reference by relating the wind power with the triangular wave is proposed in [98]. This method reduces capacitor size by 10% of its projected size.…”

Abstract:Wind energy is one of the most common types of renewable energy resource. Due to its sustainability and environmental benefits, it is an emerging source for electric power generation. Rapid and random changes of wind speed makes it an irregular and inconsistent power source when connected to the grid, causing different technical problems in protection, power quality and generation dispatch control. Due to these problems, effective intermittent smoothing approaches for wind power output are crucially needed to minimize such problems. This paper reviews various intermittent smoothing approaches used in smoothing the output power fluctuations caused by wind energy. Problems associated with the inclusion of wind energy resources to grid are also briefly reviewed. From this review, it has been found that battery energy storage system is the most suitable and effective smoothing approach, provided that an effective control strategy is available for optimal utilization of battery energy system. This paper further demonstrates different control strategies built for battery energy storage system to obtain the smooth output wind power.

-Day by day wind power technology is more dominating on the other types of renewable energy sources. Out of different types of generators doubly fed induction generator is more popular due to its superior controlling characteristics of active and reactive power at sub synchronous and super synchronous speed. But whenever there is any fault on the grid which causes voltage dip, the performance of the DFIG is affected since its stator and rotor are connected to the grid. When voltage sag occurs on the stator terminals, a transient current appears on the rotor converter which may damage the rotor side converter. The grid code suggests that these wind power plants should remain connected to the grid under such circumstances and contribute the fault current safely. But it is difficult to satisfy for DFIG connected wind plants. This paper presents the feed forward current regulator for rotor side converter of DFIG and analyses its low voltage ride through capability.

“…Popular approaches include but not limit to the pitch angle control which is cheap but slow in response [5], dynamic braking resistor (DBR) which is fast and cost-effective but causes additional power loss [6], and fault current limiter (FCL) which is reliable and cost-effective but is more common in transmission level rather than distribution level [7]. Centralized electrical devices in the family of flexible ac transmission systems (FACTs) are favorable alternatives due to their high response speed and broad control diversity.…”
