Testo completoThe problems linked to global warming imply the reduction of anthropogenic emissions of greenhouse gases. There are three pillars for decarbonizing energy systems, including the use of renewable energy. These are often assimilated to the electrical energy produced by the sun, wind, hydraulics or biomass. However, this electrical energy does not allow a deep decarbonization of all consumption sectors. The use of gas produced from these renewable energies and called "green gas" can overcome this by substituting fossil gas. The study of the penetration of these "renewable gases" is the subject of this thesis. To analyse the contribution of green gas to the decarbonization of energy sectors, the work carried out uses the long-term prospective model POLES (Prospective Outlook on Long-term Energy Systems). A module was created in the model to include a detailed representation of the green gas production system, linking resources to uses. The technologies of anaerobic digestion, gasification of biomass and the transformation of electricity into gas called power-to-gas have been modelled and their contributions in the energy consumption of consumption sectors estimated. The results show that renewable gas technologies play a role in the energy transition by doubling the production of fossil gas in the second half of the XXIst century. This gas allows the decarbonisation of the transport, industry and agriculture sectors. Nevertheless, the deployment of technologies is directly linked to the technical progress expected in the future because, at present, these technologies are for the majority too expensive to be competitive with the use of natural gas without carbon tax. In addition, development stems from the availability of local potential in terms of the biomass resources mobilized. Development trajectories are therefore quite different depending on local contexts, both in terms of resource availability and in terms of the political incentives to promote the deployment of green gases

Testo completoStand alone systems supplied only by a photovoltaic generator need an energy storage unit to be fully self-sufficient. Lead acid batteries are commonly used to store energy because of their low cost, despite several operational constraints. A hydrogen-based energy storage unit (HESU) could be another candidate, including an electrolyser, a fuel cell and a hydrogen tank. However many efforts still need to be carried out for this technology to reach an industrial stage. In particular, market outlets must be clearly identified. The study of small stationary applications (few kW) is performed by numerical simulations. A simulator is developed in the Matlab/Simulink environment. It is mainly composed of a photovoltaic field and a storage unit (lead acid batteries, HESU, or hybrid storage HESU/batteries). The system component sizing is achieved in order to ensure the complete system autonomy over a whole year of operation. The simulator is tested with 160 load profiles (1 kW as a yearly mean value) and three locations (Algeria, France and Norway). Two coefficients are set in order to quantify the correlation between the power consumption of the end user and the renewable resource availability at both daily and yearly scales. Among the tested cases, a limit value of the yearly correlation coefficient came out, enabling to recommend the use of the most adapted storage to a considered case. There are cases for which using HESU instead of lead acid batteries can increase the system efficiency, decrease the size of the photovoltaic field and improve the exploitation of the renewable resource. In addition, hybridization of HESU with batteries always leads to system enhancements regarding its sizing and performance, with an efficiency increase by 10 to 40 % depending on the considered location. The good agreement between the simulation data and field data gathered on real systems enabled the validation of the models used in this study

Testo completoNowadays, industrial processes must be efficient, particularly at the production level and/or energy consumption.This research work aims at improving the process efficiency by analysing the influences of disturbances on their behaviour, from the conception phase to the synthesis of controller/observer, in an integrated approach.The disturbance rejection problem is first introduced as well as different control laws allowing attenuate/reject these disturbances. A control law based on the concept of derivative state variable is presented and validated while applied as disturbance rejection.In order to reject the disturbance, different physical variables must be estimated, such as state variables, derivative state variables as disturbance variables. An unknown input observer based on the bond graph representation is recalled and extended in the multivariable case. It is the first theoretical contribution of this work.We thus compare the efficiency of different so-called «modern control laws» for the disturbance rejection problems by simulation with the Torsion-Bar system example. We analyse the efficiency of our approach. One extension to the Input-Output decoupling problem allows us to extend the disturbance rejection problem to other control law type in an integrated approach. At least, these techniques are applied on the real Torsion-Bar system and compared. We validate our approach.Since this work aims at analysing and developing efficient control laws for industrial processes, a simplified model of a hydroelectric plant is developed, in order to apply our results. A simplified bond graph model is validated with simulations

Testo completoRenewable energy sources (RES) (especially wind and photovoltaic energy) have the particular feature of being variable and the controllabity of their production is very limited. For these reason, deterministic methods applied to RES' impact studies are inappropriate. The goal of this research work is to investigate the contribution of probabilistic methods for integration studies of RES in power systems. The management of parameters variations impacts on power systems brings up news challenges to system operators. The first step is the probabilistic modeling of the power system which is the first part of our work. The second step is the development of probabilistic methods which mix a probabilistic characterization of the power systems with a probabilistic model of RES production to estimate defined reliability criteria as well as probabilistic security criteria like risk of congestion, voltage level violations, etc. A probabilistic study is thus a risk analysis study, unlike a deterministic study which consists in the failure analysis of few specific situations. Pratical applications are presented and contributions of the probabilistic methods are discussed

Testo completoPower-to-Gas could become an attractive solution for renewable electricity storage, provided that affordable electrolysers are able to operate efficiently under intermittent conditions. This work aims to assess the technical feasibility of operating intermittently a Solid Oxide Electrolysis Cell (SOEC) system around 1073 K. Realistic unfavourable conditions are considered, consisting in a standalone system operated with no external heat source and integrating hydrogen compression to 3 MPa. Two challenges are tackled in this work: i) the system power load range, limited to 60-100% due to thermal gradients, is extended via efficient control strategies, ii) procedures are defined to minimise the impact of the intermittency on the lifetime. First, a modular control strategy is proposed, consisting in the use of several SOEC units which are either operated in a tolerable power load range, or switched off. The system power load range is hence extended to 15-100% in the case of four units. A complementary control strategy, consisting in internal electrical heating, enables to extend the load range by reducing thermal gradients, but it may decrease the lifetime. Thus, it is applied to only one unit for it to follow the load curve and extend the system power load range to 3-100%. Secondly, 1800 on-off electric cycles are applied to an SOEC with no degradation increase, which shows that repeated start/stops do not decrease the lifetime. Start-up, standby and shut-down procedures are also defined. Finally, two case studies of Wind-SOEC and Solar-SOEC systems operated over one year show that, with the implemented control strategies, the SOEC system stores the applied power with an average efficiency of 91% vs. HHV, while units operate under tolerable conditions apart from one unit which follows the load curve and may have a decreased lifetime

Testo completoThe aim of this PHD is to study the potential of the island grid connected PV systems. Our study foc uses on three kind of systems: integration pf Grid-connected PV plants; Rooftop PV systems to reduce volt drops at the end of the grid and a study on an experimental system. The first part shows the PV's contribution to the Corsican electric network. The simultaneity between the load and the power given by a PV plant is studied as weIl the Effective Load Capacity of the PV systems. The second part of this thesis deal with the residential area and more precisely the support of the electrical end of line via the PV solution. Lndeed, to this day many homes still have volt drops problems. To make sure that the user has maximum comfort, we have chosen this solution because the island has an important solar potential and also because users are more and more fond ofthis kind of energy. Finally, the third and final chapter shows the experimental part of the PHD. It talks about the modelisation of a small grid-connected system located on the university site of Vignola. Five years of monitoring data were studied. Analysing the performances and the grid / inverter interaction showed the production problems linked to the frequency and impendency variations. The necessary modifications to the inverter's parameters have led to very satisfactory results. This work offers an analysis of the integration of PV units to the island's electrical network and will have to be completed by a more thorough study of the grid / inverter interaction
