Applying flywheel energy storage system to integrated power system for power quality and stability enhancement

Dynamic performance improvement of a hybrid multimachine system using a flywheel energy storage system

“…Frequency regulation of wind-based systems has been supported by FESS incorporation in various studies, such as Yao et al (2016) and Suvire et al (2012). Transient stability improvement of conventional multimachine systems and grid-connected WFs has been explored in the studies by Wang and Chen (2005) and Feng et al (2011), respectively. The investigations in isolated microgrids using flywheel energy injection have been reported in the studies by Nair and Senroy (2016) and Jin et al (2017).…”

Voltage stability analysis of DC ship power system with pulse load

“…Another method to compensate the fluctuation of pulse load is to equip the bus with an extra energy storage device. An example given in [7] shows that through the parallel of the supercapacitor energy storage system with the pulse load and control the charge/discharge cycle under the bus voltage fluctuation limitation, the supercapacitor can effectively compensate the pulse load. This method was validated through simulation but no experiment result was given.…”

The influence of different storage technologies on large power system frequency response

“…The conversion of kinetic energy to electrical energy is achieved by a variable speed electrical machine connected to the flywheel. The electrical machine in FESS can be represented by permanent magnet synchronous machine (PMSM), doubly fed induction generator (DFIG) and cage induction machine [5]- [7]. In this work, DFIG with secondary excitation is considered as FESS [6], [9].…”

“…Studies carried out in [5] demonstrate that a FESS with power rating of 1.3 MVA installed next to a 5.8 MVA wind plant can significantly smooth the frequency and active power delivered to the external grid. It was demonstrated in [7] that the introduction of the FESS enhances the system stability and improves the power quality in an integrated power system following different network disturbances-generators outages, step increase or decrease in loads, and short circuit events.…”

“…The applications of battery energy storage system, flywheel energy storage system and super-capacitor have already been realized around the world for frequency regulation [1]. Many studies have been carried out to demonstrate the effectiveness of energy storage for primary frequency control and power smoothing of renewable energy sources (RES) [2]- [7].…”
