Le territoire, actuellement dépendant à 68% des énergies fossiles, possède un fort potentiel d'énergie solaire. Afin de maximiser la production d'électricité provenant de panneaux photovoltaïques, cet article présente la conception et l'implémentation d'un nanoréseau PV-Batterie distribué en courant continu (CC) dans des locaux du secteur tertiaire. Le but principal de ce projet est de diminuer les pertes énergétiques liées aux multiples étapes de conversion, présentes dans le cas d'un nanoréseau intégrant de l'énergie solaire et distribué en courant alternatif (CA). Le nanoréseau CC déployé est détaillé en plusieurs partie : différences avec un nanoréseau CA, conception et intégration d'un système de gestion de l'énergie basé sur le protocole PoE (Power Over Ethernet).

With the emergence of the renewable energies, the DC bus could optimize electricity power efficiency for smart home (green home). Since the initial choice for alternative current transportation in 1880, the electrical architecture distributions haven't been change with one direction distribution to the consumers through high voltage lines. But AC power distribution therefore is so wasteful due to number of converters AC/AC and AC/DC with consequent energy losses (15% energy per converter). Nowadays most of renewable energy sources as solar panel are DC and all modern appliances are also DC powered (LED lighting, IT, electric car ..). We propose a smart DC grid distribution architecture for smart homes based on 2 voltages levels 48 VDC (Power over Ethernet) and 380 to 400 HVDC bus to improve electrical efficiency. Under the scope of ANR-C3µ project we present a microgrid DC bus with distributed control command for optimal energy resources management based on self-consumption and peak shaving for the grid. For data exchanges we will use Power Line Communication (PLC) now widely used in wide range of AC application (IP over AC) for the DC line and to pilot the DC microgrid. With the expérimental results feedback we could analyze the communications performances and the design for a microgrid control/command system in smart building applications.

Aujourd'hui majoritairement dépendante des énergies fossiles comme le charbon et le fioul, l'île de La Réunion dispose pourtant d'un fort potentiel solaire. Malgré l'utilisation croissante importante de l'électricité produite par des panneaux photovoltaïques, les pertes d'énergie dues au transport et les multiples conversions des sources de courant continu en courant alternatif et inversement, réduisent considérablement le rendement électrique. Si nous revenons à la proposition d'Edison, l'architecture DC pour la production et la consommation d'énergie locale présente de nombreux avantages dans le cas de l'énergie solaire. L'analyse réalisée présente une étude comparative sur le plan énergétique et financier, pour la rénovation d'un site isolé. L'autoconsommation du site grâce à des panneaux photovoltaïques, est encouragée et gérée selon différentes priorités entre les besoins de consommation des utilisateurs et le stockage de l'énergie par batteries (lithium fer phosphate). La contrainte principale réside dans la gestion de la ressource solaire sans être secouru par une solution telle que les groupes électrogènes, en se basant sur un modèle de contrôle prédictif. La comparaison est faite sur l'architecture électrique du site existante (DC-AC-DC) et après développement d'une architecture électrique en courant continu (DC-DC). Afin de quantifier précisément ces données, les résultats présentent les mesures obtenues en laboratoire, dans le cadre d'un banc de mesure expérimental permettant d'alimenter en courant continu directement par des panneaux photovoltaïques différents équipements (éclairage, chauffage, stockage). Des capteurs et pilotes environnementaux intérieurs et extérieurs sont utilisés pour identifier les prévisions de production et de consommation d'énergie. Les différences en quantités de convertisseurs, quantités de câblages, facilité de pilotage, surchauffe des équipements, en coût et en consommation énergétique sont également présentées, pour analyser les gains ou pertes obtenues selon deux solutions de gestion de la ressource solaire non secourue. ABSTRACT-In the context of climate change, it is urgent that island territories achieve energy autonomy. Today mainly dependent on fossil fuels such as coal and fuel oil, the island of Reunion nevertheless has a strong solar potential. Despite the significant increasing use of electricity produced by solar panels, the energy losses due to transport and the multiple conversions of sources from direct current to alternating current and vice versa, considerably reduce the electrical yield. If we go back to Edison's proposal, the DC architecture for local energy production and consumption has many advantages in the case of solar energy.The analysis carried out presents a comparative study on the energy and financial level, for the renovation of an isolated mountain refuge at high altitude. Self-consumption of the refuge thanks to solar panels is encouraged and managed according to different priorities between the consumption needs of users and the storage of energy by batteries (lithium iron phosphate). The main constraint lies in the management of the solar resource without being backed up by a solution such as generators, based on a predictive control model. The comparison is made on the electrical architecture of the existing refuge (DC-AC-DC) and after development of an electrical architecture in direct current (DC-DC). In order to precisely quantify these data, the results present the measurements obtained in the laboratory, within the framework of an experimental measurement bench making it possible to supply direct current directly by solar panels to various equipment (lighting, heating, storage). Indoo r and outdoor environmental sensors and drivers are used to identify energy consumption forecasts. The differences in quantities of converters, quantities of cabling, ease of control, overheating of equipment, cost and energy consumption are also presented, to analyze the gains or losses obtained according to two management solutions for the unbacked solar resource.

This feature makes them rather difficult to predict and therefore remains a major threat to nearby populated valleys. Our multidisciplinary partnership between laboratories (ISTerre: earth science and LCIS: embedded electronics, telecommunication) aims at developing a new predictive tool in order to analyse field movements using sensors. The plan is to instrument unstable slopes with a sensors network, characterised by its low consumption and cost, in order to achieve continuous monitoring of the overall shape deformation. Other monitoring techniques can be used for this particular phenomenon (photogrammetry, LIDAR …), but some significant imperfections and flaws lay within their usage. This paper presents the methods used to enable geolocation using our wireless sensors network based on LoRa (Long Range) radio transmission technology.

The contribution of the present work resides in the validation of constraints at all times thanks to the effective use of B-splines parameterization properties. The proposed improvements are validated through simulation and comparison results for a particular electro-mechanical elevator system.

This method uses only voltage as the input. Therefore, the system can be implemented with less complexity and cost. Moreover, this method effectively improves both transient and steady state. The results show that the time to achieve a steady state is around 0. 05s. At steady state, the MPPT efficiency reaches 99.8 %, and the oscillation is about 0.01 %.

The system includes the mechanical part, a Salient Permanent Magnet Synchronous Machine (SPMSM), a battery energy storage unit, a super-capacitor, a solar panel (PV) generation unit as well as the corresponding converters to DC-links. This microgrid is connected to a three-phase utility (external) grid. A port-Hamiltonian model is proposed for the system. It includes the descriptions of nonlinear characteristics and the limitations for each components as well as some typical operation demands.

This becomes an evident objective for sensors networks research. The IETF 6LoWPAN RFC proposal was developed in that sense to use the benefit of IPV6 over wirelessly connected sensors (WSN). The IEEE 802.15.4 MAC layer stack being popular in the domain of wireless sensors within constrained resources, a few 6LoWPAN adaptations already exist. In this paper, we investigate the possibility of using IPv6 for sensor networks connected through powerline communication (PLC) non-wireless mediums and demonstrate possible interoperability. This document propose the first adaptation of the IEEE 802.15.4 commons standard on PLC medium. Following this standard interface, we demonstrate the possibility to carry out data on PLC with great reliability, and low power energy requirement using our WPC TM physical layer (called Watt Pulse Communication (WPC)). This allows to benefit from the development of WSN researc...
