AI-Based Damping of Electromechanical Oscillations by Using Grid-Connected Converter

Abstract: The proliferation of grid-connected converter interfaced energy sources in Smart Grids, enhance sustainability and efficiency as well as minimizing power losses and costs. However, concerns arise regarding the stability and reliability of future smart grids due to this wide integration of power electronic devices, which are recognized to affect the dynamic response of the system, especially during disturbances. For instance, apart from the lower damping of existing electromechanical modes, new low-frequency os… Show more

“…However, according to the spectrum analysis in Section 2, the investigated MFO region of the system significantly exceeds the low-frequency oscillation, which refers to the dynamics of the generator sets (Baltas et al, 2021). Therefore, the influence of the generator on this new type of electrical oscillation can be ignored.…”

“…Assuming that frequencies of the oscillatory modes are well-detected by using the techniques presents in [28] and [29], this paper will be focused on analyzing the operation and design of the MRVM, and not the detection of the oscillations' frequency.…”

“…However, as the damping coefficient also determines the dynamic behavior of the SPC, reducing the damping ratio as suggested in [27] certainly deteriorates the overall performance of the GFMC. To overcome such a limitation, selective damping methods have also been reported [28] and [29]. However, there have been any studies that deal with the implementation of multi-band LFO damper for GFMC in a systematic manner.…”

“…That is, instead of emulating a conventional VSM, MRVM will implement a virtual machine that consists of multiple virtual rotors to attenuate simultaneously several modes in the power system with a high degree of controllability. Assuming that frequencies of the oscillatory modes are well-detected by using the techniques presents in [117] and [124], this chapter will be focused on analysing the operation and design of the MRVM, and not the detection of the oscillations' frequency.…”

“…To address such a drawback, frequency selective strategies have also been suggested in [117] and [118]. However, there are not any studies that cope with the implementation of such frequency-selective SSR damper for GFMC systematically.…”
