Design and Analysis of Tilt Integral Derivative Controller for Frequency Control in an Islanded Microgrid: A Novel Hybrid Dragonfly and Pattern Search Algorithm Approach

In this research work, a maiden approach is made for the frequency control in an islanded AC microgrid (MG). A MG can be formed by combining the different sources like renewable energy source, wind power generation and the solar energy generation. Variation in any of the source influences the MG frequency, and thus, the frequency control issue for MG is always a challenge for the researcher industry. In light of these difficulties, this paper considers a tilt integral derivative (TID) controller for the secondary frequency control of the islanded MGs and a novel hybrid dragonfly algorithm and pattern search (hDF-PS) algorithm is used to tune the controller parameters. In the proposed control conspire, some sources like microturbine, diesel engine generator and fuel cell are used which balance the load and power can demand of the MG. The novel hybrid controller is inspected on a MG test system, and the robustness and execution are assessed by considering different disturbances and parametric variations. In order to show the effectiveness of the proposed hybrid algorithm-based TID controller, it is being compared with some conventional controllers like integral, proportional integral and proportional integral derivative-based controller. It can be demonstrated that the proposed hDF-PS-based TID controller approach (because of considering organized/parametric instabilities) gives preferably better execution over the other control techniques.
