Abstract

International audience; The growing need of energy, global warming and recent nuclear power plant accidents have shown that renewable energies need to be developed for tomorrow's world. Wind energy is generally harvested using wind turbines. Unfortunately, these systems have some drawbacks such as their cost, and the amount of steel and concrete used for construction. As their size grows, their complexity increases exponentially. This paper studies an alternative solution for the production of wind energy, using a kite's traction force. The aim of this paper is to control the amount of energy produced by the kite, and to be able to fly it safely in the presence of strong wind gusts. Our theoretical work has been implemented in a scale model flying autonomously in a wind tunnel. The proposed control strategy has led to control the system output power with an accuracy greater than 95%, with unknown wind speeds varying from 7.5 to 9 m/s.

Abstract

International audience; This paper proposes a modified Perturb and Observe (P&O) Extremum Seeking Control (ESC) technique in presence of multiple maxima. ESC is applied to single-phased grid-connected photovoltaic (PV) arrays which have to provide maximum power irrespective of solar irradiance conditions. In particular, partially shadow conditions may lead to steady-state power curves exhibiting multiple maxima. The power harvested from the PV generator is injected in the single-phased power grid by using two power converter stages: step-up DC-DC converter and DC-AC inverter. When multiple power maxima exist, the amplitude of the perturbation signal plays an important role in successfully tracking the global maximum. Two amplitude modulation strategies are analyzed for the same case study: amplitude modulation by using a first-order-system-response signal and amplitude modulation by using small duty ratio square-wave signal, respectively. MATLAB®/Simulink® numerical simulations are presented in order to assess the two approaches comparatively.

Abstract

International audience; Most kite wind power systems have a great drawback that wind turbines do not have: they cannot stay in the air if the wind is not strong enough, [7-16]. As a consequence, most of the kite systems need to land when there is no wind, and to take-off once the wind is strong enough. These maneuvers are quite risky because generally the wind gets weak and turbulent close to the ground's surface. Moreover, as the wind can be strong enough at high altitude and weak close to the ground, it might lead to losses in energy production. From a material point of view, "classic" landings and takeoffs need a landing zone, ground handling or infrastructure (such as pylons) that reduces the advantages of kite systems. Some ideas, such as embedded motors or helium balloons, might solve this problem, but they have their own drawbacks such as the weight of the motor and its battery, the necessity of a conductive cable or the need to refill the balloons. The following paper studies a solution called "reverse pumping". It basically consists of providing kinetic energy to the kite by pulling the kite with a rope. This kinetic energy is then transformed into potential energy by gaining altitude. This technique allows to keep the kite airborne in total absence of wind. This paper will study the reverse pumping principle, the constrains on the aerodynamical model, flight simulations and will present the experimental setup used to validate the theoretical study.

Abstract

International audience; - In near future, Plug-in Hybrid Electric Vehicles (PHEVs) will replace conventional vehicles. Considering the bidirectional nature of PHEVs, this paper proposes a Housing Peak Shaving Algorithm (HPSA) for housing composed of a PHEV. In addition to prohibiting the electricity subscription overruns caused by PHEV charging, HPSA reduces subscribed power. The application of this algorithm at a group of housing forming a low voltage residential electric grid will help to minimize the aging rate of MV/LV transformer and to respect the standard related the voltage quality of the energy supplied. Thus, HPSA can be assimilated to both Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) concepts.

Abstract

International audience; Plug-in Hybrid Electric Vehicles (PHEVs) will strongly penetrate in the car fleet. Based on databases of the houses Daily Loads Profiles (DLPs) and on a probabilistic algorithm of PHEVs connections in residential electric grid areas, this paper determines the minimal charging current or PHEVs charging power which assures that the batteries reached the desired State of Charge (SOC) at the departure time without any charging restriction during peak hours. A dynamic optimization algorithm programming which defines an optimal constant charging current for the PHEV is developed. If charging occurs at home, the application of the proposed optimal algorithm on 10 000 cases shows statistically that a load power chargers for PHEVs charged in residential electric grid areas equals to 373W (230Vx1.62A) ensures that 99.4% of the PHEVs batteries have a SOC equals to 100% for the next use.

Abstract

International audience; The search for novel renewable energy resources led to investigate a resource, that was once considered a complex, unpredicted and difficult to be controlled, that is sea waves. It has attracted a particular attention in western Europe, as waves on the Atlantic coast seem to hold a huge energy that needs to be exploited. In the course of this paper, an introduction into wave energy, as well as, some examples on energy conversion systems are presented. As a study case, a pumping-type system with a vertical displacement is considered. A formulation of the forces acting on its floating part is done in order to calculate its average power. Three basic methods of controlling the proposed system are explained and compared taking into account the case of regular and irregular waves.

Abstract

International audience; This paper presents a control scheme of a closedorbit kite generator system (KGS), which is a wind-based energy producing system with a relaxation cycle. Such a system is divided into two main parts: a kite with its orientation mechanism and a power transformation system. Starting from a given closed orbit, the optimal tether's length rate variation (kite's tether radial velocity) and the optimal orbit's period are found. A trajectory-tracking control is developed for the kite's orientation. The power transformation system controls the kite's tether radial velocity and transforms the mechanical energy generated by the kite into electrical energy that can be added to the grid. A Matlab/simulink model of the KGS is employed to observe its behavior, and to insure the control of its mechanical and electrical variables. In order to improve the KGS's efficiency in case of changing wind speed, a maximum power point tracking (MPPT) algorithm is proposed.
