چکیده مقاله :
To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal power injection and rate of change of frequency (RoCoF). Displacement of conventionalsynchronous generators by non-inertial units such as wind or solar generators will result inreduced-system inertia affecting under-frequency response. Frequency control is important toavoid equipment damage, load shedding, and possible blackouts. To improve the frequencyresponse of low-inertia power system Wind generators along with energy storage systems canbe used. Moreover, FFC ensures optimal use of energy from wind farms and storage units byeliminating the inflexible de-loading of wind energy and minimizing the required storagecapacity. The efficacy of the proposed FFC is verified by using the simulation results on thelow-inertia hybrid power system.
