The proposed system uses an algorithm that works on the admittance of the system,for estimating the reference values of generated currents for an off-grid wind power harnessing unit(WPHU).The controller controls the voltage and maintains the frequency within the limits while working with both linear and nonlinear loads for varying wind *** admittancealgorithm is simple and easy to implement and works very efficiently to generate the triggering signals for the controller of the *** wind power harnessing unit comprising of a squirrel cage induction generator,a star-delta transformer,a battery storage system and the control unit are modeled using Matlab/Simulink *** isolated transformer with a star-delta configuration connects the load and the generator circuit with the controller to reduce the dc bus voltage and mitigate current in the neutral *** response of the system during the dynamic loading depends on the best possible compensator proportional-integral(PI)*** antlion optimization algorithm is compared with particle swarm optimization and grey wolf optimization and is found to have the advantages of good convergence,high efficiency and fast calculating *** is therefore used to extract the optimal values of frequency and voltage PI *** simulation results of the controlalgorithm for the WPHU are validated in a real-time environment in a dSpace1104 laboratory set *** algorithm is proven to have a quick response,maintain the required frequency,suppress the current harmonics,regulate voltage,help in balancing the load and compensating for the neutral current.
