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.

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®.

In this thesis, a model for a grid connected converter for a PV system is described and simulated. A brief explanation of the main characteristics and how voltage source converters and photovoltaic systems work is made before presenting two models that describe the performance and behavior of a VSC and a PV array. First, the models are presented in a theoretical framework, and then several simulations are carried out. Two different scenarios are presented in which diverse features of the converter model are shown, as well as presenting some applications for the PV model. All the models and simulations are built and performed in Matlab and Simulink software.

Integrated multiport converters for interfacing several power sources and storage devices are widely used in recent years. Instead of using individual power electronic converters for each of the energy sources, multiport converters have the advantages including less components, lower cost, more compact size, and better dynamic performance. In many cases, at least one energy storage device should be incorporated. So, it is very important for the port connected to the energy storage to allow bidirectional power flow.

The ever-increasing need for higher efficiency, smaller size, and lower cost make the analysis, understanding, and design of energy conversion systems extremely important, interesting, and even imperative. One of the most neglected features in the study of such systems is the effect of the inherent nonlinearities on the stability of the system. Due to these nonlinearities, these devices may exhibit undesirable and complex dynamics, which are the focus of many researchers. Even though a lot of research has taken place in this area during the last 20 years, it is still an active research topic for mainstream power engineers. This research has demonstrated that these systems can become unstable with a direct result in increased losses, extra subharmonics, and even uncontrollability/unobservability. The detailed study of these systems can help in the design of smaller, lighter, and less expensive converters that are particularly important in emerging areas of research like electric vehicles, smart grids, renewable energy sources, and others. The aim of this Special Issue is to cover control and nonlinear aspects of instabilities in different energy conversion systems: theoretical, analysis modelling, and practical solutions for such emerging applications. In this Special Issue, we present novel research works in different areas of the control and nonlinear dynamics of energy conversion systems.

Grid Connected Converters: Modeling, Stability and Control discusses the foundations and core applications of this diverse field, from structure, modeling and dynamic equivalencing through power and microgrids dynamics and stability, before moving on to controller synthesis methodologies for a powerful range of applications. The work opens with physical constraints and engineering aspects of advanced control schemes. Robust and adaptive control strategies are evaluated using real-time simulation and experimental studies. Once foundations have been established, the work goes on to address new technical challenges such as virtual synchronous generators and synergic inertia emulation in response to low inertia challenges in modern power grids. The book also addresses advanced systematic control synthesis methodologies to enhance system stability and dynamic performance in the presence of uncertainties, practical constraints and cyberattacks. Addresses new approaches for modeling, stability analysis and control design of GCCs Proposes robust and flexible GCC control frameworks for supporting grid regulation Emphasizes the application of GCCs in inertia emulation, oscillation damping control, and dynamic shaping Addresses systematic control synthesis methodologies for system security and dynamic performance

In recent years, with the depletion of fossil fuels and the deterioration of the environment, in order to meet the demand for energy, the reform of traditional energy structure is imperative. Therefore, renewable energy such as wind energy and solar energy has been vigorously developed. The interface between the DC bus and the grid in the PV system requires an intermediate power electronics bridge to convert the electrical energy into the corresponding voltage level and type. As the Grid-connected inverter is the most important interface device, it has direct impact on the PV generation system and the operation of the network. In this project, the three-phase grid-connected inverter system and the PV generation system have been modeled. In this project, I will analyze multiple types converter in microgrid including single/three phase rectifier, single/three phase inverter and four types of converter. The main part of this project is introduce operating principles about each power converters. The numerical example will also be given to show the design steps. After the analysis, the simulation will be achieved in MATLAB/Simulink.
