Microgrid Frequency Control Using the Virtual Inertia and Anfis-Based Controller

The main challenge in associate islanded micro grid (mg) is the frequency stability due to the inherent low-inertia feature of distributed energy resources. that is why, energy storage devices, are utilized in mgs as the promising sources for grid short-term frequency regulation. though energy storage devices, improve the dynamic operation of the load-frequency control (lfc) system, these devices increase system costs. moreover, the modification or uncertainty of the system parameters will significantly degrade the performance of the conventional lfc system. this article proposes the execution of rotating-mass-based virtual inertia in double-fed induction generator (dfig) to support the first frequency control associated an adaptive neuro-fuzzy inference system (anfis) controller, as secondary frequency control. the simulation conclusions illustrate that the suggested control scheme ameliorate the dynamic operation of the lfc system and also the studied islanded mg remains stable, despite severe load variation and parametric uncertainties.
