In this paper an analysis of a power converter based on a modular multilevel topology is discussed. A mathematical model of the MMC is developed in order to evaluate its dynamic behavior and to better understand the incidence of the circulating current phenomenon which could compromise converter performance in variable speed drive applications. In fact, if such problem is not properly addressed reliability problems arise.

This paper presents the control and energy management of a hybrid system that comprises wind (Doubly Fed Induction Generator DFIG) and Photovoltaic (PV) generation subsystems, a battery bank, and an AC residential load, connected to the utility grid which is used as a backup source. The objectives of this system are, primarily, to satisfy the house load power demand and, second, to manage the power between its different components. A comprehensive nonlinear model and a control design of the studied power system have been developed in this paper. Simulation results using MATLAB/Simulink illustrate the performances of the proposed supervisor controller under several operation modes.

Solar energy reaching a given surface depends directly on sun's orientation and sensor's position. Concentrated solar power systems are using sun-tracking heliostats to reflect maximum solar heat to a thermal receiver mounted atop a central power tower. The focused heat boils water within the thermal receiver and produces steam to supply a turbine for power generation. Since sun's rays are constantly variable throughout a day one should constantly change the position of the heliostat using an orientation system. First, a program for calculating the daily, monthly and yearly position of the sun for any earth place is developed using MATLAB software. Then an orientation system based on a robot manipulator in order to allow the heliostat to move for sun's radiation tracking is proposed and described. The results show that this system allows accurate positioning and gives a higher solar energy yield in comparison to a fixed one. Each heliostat will be equipped with this system. For accurate and instantaneous automatic control of the robot manipulator a Programmable Logic Controller (PLC) is used. Satisfying simulation results have been obtained.

The paper suggests a novel architecture of PV-powered Modular Multilevel Converter for building integrated photovoltaics. A grid-tied single-star configuration has been proposed. In particular, three different cell topologies have been analyzed and compared in terms of number of PV modules and rated voltages of semiconductor devices. Finally, a control strategy has been suggested in order to deliver to the grid the maximum power available from the PV modules at unity power factor.

This paper presents simulation studies and preliminary experimental results related to a hybrid battery-ultracapacitor energy source for an urban electric car. A proposal of energy management strategy based on fuzzy logic is introduced. Control strategy for the hybrid source is designed to achieve high-efficiency and high-power source for the vehicle with a relatively small battery storage. Simulation studies show the possibility to use information from a navigation system to improve performance of the source.

Several methods can be used in the current control loop of a doubly-fed induction generator systems. The PI controllers in the rotating frame system oriented to the stator voltage (VOC) or flux (FOC) are the most popular control methods. In this case, controller response in each axis also gives an answer to the second axis. Therefore, a transient state of the system response is longer and may have additional oscillations. To avoid the long answer of the controllers and speed up the operation of current control loop, the decoupling structures are used. The paper presents three methods of decoupling implementation in a rotor current control loop for doubly fed induction generator. The paper is focused on the operation with unbalanced grid voltage conditions and on standalone operation with unbalanced load. A simulation results with full scale model of doubly fed induction generator are presented in the paper.

The paper summarizes the status and progress of Work Package 8 of the MARINA Platform European FP7 R&D project. MARINA covers multi-purpose offshore renewable energy platforms and a key purpose is to look into synergies in combining wind energy with ocean energy technologies. To have wind and wave placed on the same site may have several advantages in terms of using common facilities and infrastructure but also challenges. The activities reported cover wind farm layout, offshore electrical infrastructure as well as integration challenges and opportunities of offshore renewable energy.

Cascaded doubly fed induction machines (CDFIMs) could be of interest for wind energy conversion systems. The investigation of their steady-state characteristics is currently considered as a state of the art topic. Within this trend, the paper is aimed at the analysis of the steady-state operation of CDFIMs considering both similar and different rotor phase-sequences. Following a recall of the CDFIM basis, its a-b-c model, with the motor convention accounted for, is derived. Its schematic bloc diagram is then established and implemented which enables a simulation-based analysis of its steady-state characteristics under motor operation. While the steady-state analysis of the generator operation is achieved by experiments carried out on a test bench where the wind turbine is emulated by a DC motor.
