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.

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®.
