Fuzzy control based virtual synchronous generator for self-adaptative control in hybrid microgrid
Energy Reports, 2022 Maintaining the stability of low-inertia microgrid becomes a key challenge in the presence of high penetration of renewable energy sources. However, in such systems, the virtual inertia values are often fixed constants, and the choice of their values ...

Optimal Placement of Virtual Inertia in Power Grids [PDF]
IEEE Transactions on Automatic Control, 2017 A major transition in the operation of electric power grids is the replacement of synchronous machines by distributed generation connected via power electronic converters. The accompanying "loss of rotational inertia" and the fluctuations by renewable sources jeopardize the system stability, as testified by the ever-growing number of frequency ...

ARI and ARID control of virtual synchronous generator for frequency response improvement
IET Renewable Power Generation, 2021 The modern power system is progressing from a centralised generation having synchronous generators to the distributed generation having the large‐scale integration of renewable energy sources. These renewable energy sources are interfaced with the system

Optimal Allocation of Virtual Inertia Devices for Enhancing Frequency Stability in Low-Inertia Power Systems [PDF]
2021 North American Power Symposium (NAPS), 2021 As renewable resources gradually replace conventional generation based synchronous machines, the dynamics of the modern grid changes significantly and the system synchronous inertia decreases substantially. This transformation poses severe challenges for power system stability; for instance, it may lead to larger initial rate of change of frequency and
