Investigations on testing and topologies of grid connected PV Inverters- A Comprehensive Review

Abstract

The main cause of the Electrical power conversion which is generated with the help of renewable energy (Solar) is the Photo Voltaic (PV) inverter. This PV inverter performs a vital role in conversion of the electrical power in to the required i.e., from DC to AC by maintaining the standards which is synchronized to Grid or directly to the appliances. Designing of the PV inverter should be considered with the performance, safety and interconnection of grid characteristics of PV systems. Otherwise this may reflect on the entire system making it to an abnormal and also becomes a cause in increase of the severity. IEEE 1547 standard for the integration of energy resources with electrical power systems is considered. In this paper, a complete review on the test instructions, islanding and power quality which are to be considered in PV inverter as per the standards are presented. This review work also gives complete information of PV inverter performance at different levels with a clear step by procedure which provides a complete information in maintain the standard tests and helpful of further developments.
