Frequency regulation of wind energy integrated power system using a novel optimized type II fuzzy tilted integral derivative controller

Abstract

The prime objective of the proposed research work is to study the frequency response of a wind plant integrated two area power system under sudden load disturbances when considered under deregulated market environment. The thermal power system has been modelled with suitable generation constraint and governor dead bands. Erratic behaviour of wind power makes the power system very sensitive to frequency deviations and proper frequency control is needed for stability. A new tilted integral derivative controller (TID) with type II fuzzy controller is considered as secondary controller for minimizing frequency fluctuations. The gains of the controller are set at an optimal value with the help of newly designed hybrid Dragonfly algorithm–Whale optimization algorithm for proper control action. System dynamic performance with and without renewable penetration is studied and robustness of the proposed controller is established under various market conditions and varying renewable power integration.

Resilient and Sustainable PD-(1+PI) Controller for a Smart grid in Uncertain Environments

“…Harris Hawks-based Cascaded PD-PI controller at high load disturbance has been shown in [14]. To reduce frequency fluctuations, a hybrid Dragonfly algorithm-Whale optimization algorithm tuned tilted integral derivative controller (TID) with type II fuzzy controller has been presented in [15]. Grasshopper-tuned cascaded fuzzy PD-PI controller has been reported for an interconnected three-area system with wind and solar thermal system and a conventional one [16].…”
