The major concern in a growing power quality is harmonics distortion which is caused by the non-linear nature of the loads. This problem has drawn much attention from utilities, users and industries. To reduce the harmonic distortion for improving the power quality of the system a custom power devices has been proposed. A static compensator (STATCOM) is implemented at distribution level for overcoming several power quality problems. In this paper, new control technic i.e AI is proposed on shunt compensator to estimates the weight values of load currents. The control approach is based on the convergence of the load currents and property of the input signal. A working prototype of the STATCOM is implemented using three-phase VSC and AI control technique based PWM controller approach is developed in MATLAB/SIMULINK.

This paper presents the cascade multilevel UPQC for sag and swell mitigation of a grid connected hybrid system. Power quality is the major problem facing by today’s power system. Due to the use of power electronic converters and devices the harmonics are injected into the grid that may result in grid failure. To mitigate these harmonics custom power devices are used. UPQC is the custom power devise that is used in this paper. The seven level cascade multilevel converter is used for both the series and shunt inverters of UPQC for better harmonic distortion. This system is connected to the PV+WIND hybrid system to provide effective utilization of the resources. The UPQC contains a DC link which controls the Sag and Swell, LG Fault and improves the power quality of the system. This system is simulated in MATLAB/SIMULINK

Variable-Frequency Prony Method in the Analysis of Electrical Power QualityThe article presents a new modification of the the least squares Prony method. The so-called variable-frequency Prony method can be a useful tool for estimating parameters of sinusoidal components, which, in the analyzed signal, are characterized by time-dependent frequencies. The authors propose use of the presented method for testing the quality of electric energy. It allows observation of phenomena which, when using traditional methods, are averaged in the analysis window. The proposed modification of least squares Prony method is based on introduction and specific selection of a frequency matrix. This matrix represents frequencies of estimated components and their variability in time.
