Overview of connection topologies for grid-connected PV systems
2014 IEEE 27th Canadian Conference on Electrical and Computer Engineering (CCECE), 2014This paper presents an overview of grid connected Photovoltaic (PV) systems and their inverters. First, the components of the PV systems and recent research activities regarding these components are discussed. Then, a PV array model, based on the Shockley diode equation, is introduced and a typical 60 W solar panel is modeled with Matlab script file ...

Development of grid-connected inverters for micro-grid
2014 Clemson University Power Systems Conference, 2014As an important part of the smart grid, the micro-grid contains distributed energy sources, loads, and control devices. An energy storage system and a doubly fed induction generator based wind turbine associated with an ultracapacitor are the main micro grid sources in this paper.

Control and simulation of grid-connected micro-grid
2012 IEEE Power and Energy Society General Meeting, 2012Grid-connected control method and simulations of the micro-grid are presented in the paper. The typical configuration of the micro-grid is presented. In order to ameliorate the effect of power quality during the grid- connected process, the power flow in the micro-grid is analyzed based on the characteristic of frequency and active power, and the time ...

Connecting arbitrary data resources to the grid
2010 11th IEEE/ACM International Conference on Grid Computing, 2010Many scientific grid systems have been running and serving researchers for many years around the world. Among them, Globus Toolkit and its variants are playing an important role as the basis of most of those existing grid systems. However, the way data is stored and accessed varies.

Grid-Connected Photovoltaic Generation System
IEEE Transactions on Circuits and Systems I: Regular Papers, 2008This study addresses a grid-connected photovoltaic (PV) generation system. In order to make the PV generation system more flexible and expandable, the backstage power circuit is composed of a high step-up converter and a pulsewidth-modulation (PWM) inverter.

A single-phase grid-connected PV inverter with improved grid-connected current
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015This paper presents an effective method, which can address the existing dc-link double-line-frequency voltage ripples in single-phase grid-connected PV inverters, to improve the grid-connected current. The instantaneous power pulsations at grid side cause double-line-frequency fluctuations of the dc-link voltage in single-phase grid-connected PV ...

A grid-connected switched PV array
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015In this paper, a grid-connected version of the switched PV array will be presented. The PV array consists of n parallel-connected strings and m series-connected modules per string, i.e. an array with a dimension of (m × n). Using the proposed switched PV approach, each string can be reconfigured to form two parallel strings of m/2 modules per string ...
