Abstract

With the advancement of technology non-conventional resources of energy are playing a major role in generating electricity. Non conventional sources of energy are used in various forms of energy such as solar energy, wind energy, hydro power, geothermal energy, bio energy and various energy storages. The wind energy generation is one of the efficient source of generating electricity. The wind generating system is facing problem when connected to the grid which creates serious power quality issues and need to be solved. This paper presents the power quality issues concerned in wind energy generation, utilization and its grid penetration in an electrical grid. The fluctuations in wind generated power causes stability problems. The power quality of the wind generating source in the electrical network is affected by the weak interconnection of the source. Nowadays, there are various power quality issues such as voltage variation, flicker, active power, reactive power, harmonics and electrical behavior of switching operation. These are measured according to national/international guidelines. This paper mainly explains the power quality problem faced during the setting of wind turbines with the grid. Nowadays there is a huge improvement in technologies, and thus using various new techniques, the wind turbine [1] has to control the reactive power over a wide range.

Abstract

Power quality problems are basically concerned with voltage fluctuations, voltage sag, swell, frequency distortions, and harmonics in the current at the load side. These problems lead to failure, and mis-operation of various sensitive loads. Distribution system networks, critical industrial loads and other commercial operations suffer from various power quality problems which can lead to considerable financial losses. This paper represents a grid connected PV based Dynamic Voltage Restorer (DVR) to mitigate deep voltage sags. The existence of three phase fault in the system affects the grid voltage and current. DVR injects voltage in series with the system to mitigate the voltage sag. An efficient DC-DC step up converter with a three level (6pulse) VSC (Voltage Source Converter) is utilised to give stable and harmonic free supply to the Grid. The simulation results and analysis show the validation of proposed DVR.

Abstract

Mitigation and analysis of Very Fast Transient Overvoltages (VFTO) is very important in Gas Insulated Substations (GIS). In this paper, a power transformer rating of 400MVA in 1000kV gas insulated substation has been considered and different techniques for mitigation and analysis of Very Fast Transient Overvoltages (VFTOs) are applied and the outcomes are analyzed by the application of Discrete Wavelet Transform (DWT) as the wavelet transform is superior and a powerful tool for extraction of high frequency transient signals and gives the crisp output. The proposed system has been designed with MatLab platform and the designed system is simulated to evaluate the peak values of Very Fast Transient Overvoltages (VFTOs) generated both at transformer (Vtr) and open end of (Voc) with and without RC – filter, ferrite ring and a nonocrystilline. The results show that the peak value of Very Fast Transient Overvoltages (VFTOs) can be considerably reduced by introducing RC–filter ferrite ring and nanocrystalline methods. The outcomes are explored to wavelet transform for transient information. By the application of wavelet transform, it has concluded that an exact measurement VFTOs can be obtained and is shown in the results.

Abstract

In this paper a detailed description of fuzzy logic based MPPT (Maximum Power Point Tracker) scheme for the SEPIC converter is presented for tracking the maximum power point in the PV array. Due to the fact that the output of the solar panel is not linear in nature, it has a point of maximum power which changes due to the variation in irradiance and temperature. Thus, MPPT scheme provides an opportunity for a solar panel to operate continuously at peak power point. In this work, the authors have presented the co-ordinated sequences of P&O (Perturb and Observe) and fuzzy logic control are provided to form a single algorithm for MPPT of PV DC-DC SEPIC converter for PV inverter applications. For the SEPIC converter, the fuzzy logic MPPT scheme shows a high accuracy in the current waveform and provides a constant voltage waveform and is also utilized to get the accurate sine wave output of the inverter used in the PV system. Total Harmonic Distortion is also computed for the basis of representing harmonics in the sine wave output of the inverter used in the PV system.

Abstract

In recent years, non conventional energy resources (solar energy, wind energy, tidal energy) has been the most effective utilization of generating electrical energy, and also widely used in transmission and distribution systems. In this paper, a study of two different photovoltaic systems, namely photovoltaic system using a single-stage converter and photovoltaic system using a two-stage converter has been analyzed. In a two-stage converter, the first stage has a DC-DC converter, which provides galvanic isolation and also changes the DC voltage level. The second stage has an inverter, which converts DC to AC and provides good quality current to the grid. In the single stage converter, flyback inverter is employed. This paper concludes with a discussion of the more efficient and reliable photovoltaic system between single and two stage systems.
