(Special Issue: Kenneth R. Laker) An Approach to Improve Power System Resiliency in Grid-Connected Wind Turbine Generator Power System
Authors: , ,
Abstract: A new concept of optimal Point-on-wave (PoW) switching to curtail the power system resiliency of the wind power plant connected with a transformer is presented. Optimal PoW switching targets are determined using mathematical analysis and tested on the simulation model. The said simulation model has been developed using PSCAD/EMTDC software for system parameters of the existing wind power plant electrical network of Gujarat, India. The proposed optimal PoW-based method is capable of reducing the magnetizing inrush current exceptionally. Further, the proposed technique is also efficient in smoothening the voltage profile and decreasing harmonic contents in the supply, which improves the power quality of the wind power plant electrical network. Afterwards, to demonstrate the proposed technique based on optimal PoW, a hardware model has been developed in a laboratory environment. The result of the hardware model provides a promising outcome as proof of the proposed technique. In the end, a comparative evaluation with a recently developed technique is also carried out where it has been observed that the proposed technique is providing superior results.
