The size and location of DG are the crucial factors in the application of DG for loss minimization. This book presents an algorithm for the identification of bus location using Sensitivity analysis and also an algorithm for the determination of size of the DG using PSO. This methodology is tested on IEEE 15 bus system. By installing DGs at all the potential locations with the determined sizes, the total real power loss of the system has been reduced by 83% and the voltage profile of the system is also improved. The harmonics that are present in the system are reduced by placing capacitors at...

An integral terminal sliding mode control design was proposed to enhance the power quality of wind turbines under unbalanced voltage conditions. The design combines the robustness, fast response, and high quality transient characteristics of the integral terminal sliding mode control with the estimation properties of disturbance observers. It was successfully implemented to both the rotor-side (RSC) and grid side (GSC) converters of a DFIG-based wind turbine. The controller gains were auto tuned using a fuzzy logic approach. Its performance was assessed in the presence of deep voltage sags...
