The present work investigates a real time implementation of a photovoltaic grid connected chain, based on fuzzy logic MPPT controller (FLC). The implementation is realized on a dSPACE 1104 single board, controlling a boost chopper in the PV array side and a VSI inverter in the grid side. The FLC tracks permanently the maximum power point of the PV array without any prior information on the syst...

There is increasing utilization of photovoltaic (PV) grid-connected systems in modern power networks. Currently, PV utilize transformerless inverters that have the advantages being low cost, weight, a small size, and highly efficient. Unfortunately, these an earth leakage current problem due to absence galvanic isolation. This phenomenon represents safety electrical problems for those systems. ...

This paper presents a single phase five level photovoltaic (PV) inverter topology for grid connected PV systems with a novel Pulse Width Modulated (PWM) control scheme. Two reference signals identical to each other with an offset equivalent to the amplitude of the triangular carrier signal were used to generate PWM signals for the switches. A digital Proportional-IntegralDerivative (PID) curren...

Among various types transformerless grid-tied photovoltaic (PV) inverters, multilevel (MLIs) are mostly popular their ability transmit reactive power...

This paper presents a novel concept of utilizing the photo voltaic solar farm inverter as STATCOM(Static Compensator), named PV-STATCOM, in order to improve the voltage profile of the power system. The entire STATCOM is able to transmit either active or reactive power into the grid. This system is connected to a 14 BUS IEEE standard grid as a case study to simulate the performance of the system...
