Simulation of Photo Voltaic Cell Based DSTATCOM for Power Quality Improvement

Abstract

Solar energy being naturally available in abundance and pollution free is one of the most promise sources. The PVbased system based electrical energy generation have been progressively more because of the cost of energy produced from fossil fuels is very high. The important operational requirement in power network at both transmission and distribution levels. Whenever there is a penetration of PV cell power to the low voltage distributed grid.. Power quality is the foremost problem that occurs between grids to end user lines. A Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency those consequences in a failure or a mis-operation of end user equipment’s. The issue of power quality is going to take newer dimensions. In mounting countries like India, where the dissimilarity of power frequency and many such other determinants of power quality are themselves a sternproblem, it is very vital to take positive steps in this direction. The present work is to identify the important concerns in this area and hence the measures that can enhance the quality of the power are suggested. In this paper one of the FACTS controller devices D-STATCOM is used to improve the voltage regulation thereby the power system stability. DSTATCOM is the one of the power quality compensating device which will rectifies the power quality problems such as voltage sag and swell which occurs in high voltage power transmission lines. The use of distributed energy resources is increasingly being pursued as a supplement and an alternative to large conventional central power stations. Distribution Static Compensator (DSTATCOM) is proposed for compensation of reactive power and unbalance caused by various loads in distribution system. The circuit was simulated by using Simulink / MATLAB software and to solve the voltage sag and swell and the model was developed. By using this DSTATCOM device in the MATLAB SIMULINK model the problem occurred has been rectified.
