Inertia and primary frequency response support of VSG-controlled PMSG-WT enabled by utilization factor control of fuel cell system and ultracapacitor

open access: yesInternational Journal of Electrical Power & Energy Systems
This work proposes integrating hybrid energy sources including ultracapacitor (UC) and fuel cell (FC) which are controlled by the virtual synchronous generator (VSG) strategy into a VSG-controlled PMSG-WT to provide frequency support. The UC emulates the

IMPLEMENTATION OF VIRTUAL SYNCHRONOUS GENERATOR METHODOLOGIES FOR RENEWABLE INTEGRATION [PDF]

open access: yes, 2017
In conventional centralized power systems, power is generated mostly by large synchronous generators (SGs), where the frequency of the grid depends on the rotational frequency of the prime mover.
