Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there have been international commitments to reduce emissions associated with conventional energy were made. Renewable energy has been gaining ground, and is seen to occupy a prominent place in the global power generation. In this context, solar photovoltaic generation systems have the opportunity to be as much as suitable to produce electrical energy very close to the electric loads. Power electronics forms a major role in connecting PV systems into grid. Multilevel converters have been increasingly used in these systems to take care of high voltage levels and reduced harmonic distortion. In this thesis, power mismatch in N-port converter system that consists of a dual active bridge (DAB) dc-dc converter and a multilevel cascaded H-bridge dc-ac inverter is analyzed, modelled and simulated with in LabView ® and Simulink®. The d-q axis current control method is developed and simulation results are presented. This control design is built to control the grid current and Capacitor voltage balancing is simulated in Matlab®/Simulink® and LabView ® by using the average model approach. Additionally, Pulse Width Modulation (PWM) techniques for H-bridge and cascaded H-bridge have been analyzed and modelled in LabView®.

Book Synopsis Analysis, Modeling and Simulation of N-port Converter for Grid Connected PV System by : Turgay Duman

Download or read book Analysis, Modeling and Simulation of N-port Converter for Grid Connected PV System written by Turgay Duman. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: The renewable energy sources such as wind, solar, and fuel cell are needed to produce electric energy to meet increasing demand on energy, shortage of fossil fuels, and global concern about fossil emission levels. Specifically solar energy has seen tremendous growth because of its several advantages such as being pollution free, little maintenance, emitting no noise and, long life time. Grid connected solar photovoltaic (PV) systems have great potential to be a distributed power source because of their modular characteristics and ease of installation. In 2011 more than 62,500 PV systems have been interconnected by utilities in the US, and the forecasts show that this number will increase to over 150,000 in 2015. Power electronics forms a major role in connecting PV systems into grid. Multilevel converters have been increasingly used in these systems to take care of high voltage levels and reduced harmonic distortion. There are some different multilevel topologies, and applications. In this thesis, a cascaded multilevel H-bridge inverter as a part of N-port multilevel converter is developed and analyzed to integrate PV system into grid. This N-port multilevel converter uses dual active bridge (DAB) converters as a front-end DC to DC converter to control power to grid and cascaded multilevel H-bridge (CHB) as a DC to AC inverter. The average model of DAB and CHB converters is developed in MATLAB ® /Simulink ® and power electronics simulation software PSIM® . A system level controller is designed which includes P&O maximum power point tracking (MPPT) for the PV, and d-q axis grid current controller for the CHB inverter. In addition the phase-shift sinusoidal PWM is developed to the 11-level CHB. The entire N-port converter system for three phases with 15 ports is modelled in PSIM ® and the controller performance is verified.

Book Synopsis Voltage, Current and Fault Control of a Multi-port Power Converter for a Grid-connected Photovoltaic System by : Thilo Janssen

Download or read book Voltage, Current and Fault Control of a Multi-port Power Converter for a Grid-connected Photovoltaic System written by Thilo Janssen. This book was released on 2016. Available in PDF, EPUB and Kindle. Book excerpt: New smart power grids apply automatically controlled power systems that require a modernization of existing technologies. Renewable energy systems such as Photovoltaic power plants convert solar energy into electricity. Conventional 60Hz transformers in such systems can be replaced by novel power converter systems, which reduce production costs, size, and improve efficiencies. This thesis presents a power interface for a large scale solar power plant, utilizing an innovative power balance and fault tolerance control to feed electricity reliably and efficiently to the medium voltage 13.8kV utility grid. This interface consists of a multi-port converter configuration which achieves a high power DC-AC conversion. Each port consists of an array of PV solar panels, a multi-level dual active bridge, a neutral point clamped inverter, and a connection circuit to the grid. This combination of ports is arranged for a three phase output. A connection to the grid entails a system level controller, which can be achieved by a voltage and current balancing control, using a nonlinear concept with integrated feedback loops. Autonomous operation requires the establishment of a fault-tolerant control algorithm, attained by a continuously monitored fault detection circuit. A novel multi-port control is proposed to realize a voltage, current and fault control strategy among cascaded ports. This control is verified in Matlab/Simulink; detailed analysis and simulation results are provided.
