This paper presents a method of integrating Active Power Filter (APF) in Photo Voltaic(PV) system. Distributed Generation (DG) concept is attracting the attention of power sector engineers throughout the world due to its technical, economical and environmental benefits. Among the various possibilities of DGs, photovoltaic (PV) systems have drawn prominent attention In spite of their high cost and poor conversion efficiency. Power quality issues such as harmonics, are inevitable in such distribution system which must be sorted out. Separate Passive/Active Filters can be used for this purpose. However single VSI Converter can be made used for processing and connecting PV energy to system as well as for power Quality improvement of the whole system. This reduces the complexity and cost of the system significantly. The proposed PV System with single converter acting as APF is not only able to track the maximum power point of the photovoltaic energy but also compensate harmonic currents from the grid line and correct the power factor. Peak detection method of control strategy is employed in APF for power quality improvement. P&O algorithm is used for achieving Maximum Power Point Tracking of the PV generator. The proposed system of APF embedded in PV system is simulated using MATLAB/SIMULINK and tested for power quality improvement under the maximum Power Point Tracking of PV generator.
In this paper load frequency control (LFC) of two area power system in deregulated environment using PI controller was studied. A two area system is considered in which all areas are interconnected by normal AC tie-lines. In each area there are two GENCOs and two DISCOs. DISCOs can buy power from GENCOs in their own area or from other areas. In the proposed system the effects of bilateral contracts between DISCOs and GENCOs are also considered. The performance of the PI controller is tested on a deregulated two area load frequency control system for different operating conditions using MATLAB Simulink tool. The results show that performance of PI controller is effective in reducing steady state error.
Due to dwindling of fossil fuels and other non renewable energy resources, there has been a considerable advancement in field of renewable energy resources. Renewable energy provides a more stable source of power which is constantly replenished and infinite. The power obtained from the renewable sources depends on the geographical conditions which are varying, hence results in variable power generation. Power electronic converters play a very important role in obtaining a constant power from the renewable resources. In this paper studies on Oscillating Water Column (OWC) based Wave Energy Conversion System (WECS) has been carried out. The work involves the modeling of system, control of the dc and ac voltage for standalone application. The controllers are designed to regulate the voltage and address certain power quality issues.
This article presents performance evaluation of real time radial distribution system with different compensating devices. The performance of real time radial distribution system was investigated using real time distribution system data with different compensating devices for different operating conditions. The performance evaluation of distribution system is analyzed by placing shunt capacitor, SVC and STATCOM independently; voltage profile and total losses are compared under different system operating conditions. To demonstrate the effectiveness of the proposed method, a 110/11KV distribution substation is selected for analyzing the performance and results are presented.
Permanent Magnet Synchronous Motor (PMSM) drives have been increasingly applied in a variety of industrial applications which require fast dynamic response and accurate control over wide speed ranges. However, there still exist challenges to design position-sensor less vector control of PMSM operating in a wide speed range, which covers both constant-torque and constant-power region. Field oriented control (FOC) of permanent magnet synchronous motor (PMSM) is one of the widely used methods for the speed control of the motor. The feasibility and effectiveness of various pulse width modulation techniques implemented for PMSM are addressed in this paper and verified by computer simulation. The whole drive system is simulated in MATLAB/SIMULINK based on the mathematical model of the system devices including PMSM and inverter. By using solar panel, the dc voltage is applied to a PWM inverter. The aim of the drive system is to have speed control by using solar panel. Simulation results show that the speed controller has a good dynamic response.
