Alex, Ansu. "Tidal stream energy integration with green hydrogen production : energy management and system optimisation." Thesis, Normandie, 2022. http://www.theses.fr/2022NORMC216.
Повний текст джерелаThe overarching aim of this thesis is to design, implement and compare different energy management strategies and optimisation approaches for a hybrid system involving floating tidal stream energy integration with green hydrogen production. Towards reaching the objectives, the individual system components are modelled initially. The annual system performance capabilities of the tidal stream energy plant are then obtained using frequently occurring daily profiles at the Fall of Warness berth in the Orkney Islands, Scotland. The transitionary operating modes of two polymer electrolyte membrane electrolyser units, when subjected to the energy from the tidal stream plant are analysed based on a rule-based approach energy management strategy. Later, a preliminary evaluation of the hydrogen production cost is assessed based on different daily hydrogen demand and daily tidal profile conditions. Further, an optimisation approach with the objective to maximise the system operating profit ensuring optimal and sufficient operations of both the electrolyser units under real system constraints, is formulated with priority for tidal energy powered hydrogen production. The optimisation problem is solved using a genetic algorithm based on the mixed integer non-linear problem. A comprehensive cost-benefit analysis based on fixed-variable costs and levelised costs factors is performed to analyse the optimal techno-enviro-economic operation of a hybrid grid connected tidal-wind-hydrogen energy system. The outcomes are compared against the rule-based approach results. The annualised profits in the optimisation approach are estimated to be 41.5% higher compared to the rule-based approach. Further, from an environmental view, the best optimisation results are approximately 47% higher than the rule-based approach results in terms of carbon emission reductions. A dynamic electrolyser capable of working at twice of its nominal power rating for limited duration, resulted particularly advantageous when coupled with tidal energy which is cyclic in nature with predictable periods of high and low power generation. Finally, it was determined that the fixed cost (FC) optimisation approach is relatively simple in terms of cost estimation. On the contrary, while the levelised cost (LC) approach yields slightly better results, it necessitates a greater prior knowledge of system operations to reasonably estimate the cost factors. The proposed method can be used as a generic tool for electrolytic hydrogen production analysis under different contexts, with preferable application in high green energy potential sites with constrained grid facilities

Повний текст джерелаThe deployment of distributed energy resources, combined with a more proactive demand side management and energy management systems, is inducing a new paradigm in power system operation and electricity markets. Within a consumercentric market framework, peer-to-peer approaches have gained substantial interest. Peer-to-peer markets rely on multi-bilateral negotiation among all agents to match supply and demand. These markets can yield a complete mapping of exchanges onto the grid, hence allowing to rethink market–grid interactions.This thesis treats three main challenges which needs to be overcome before considering real world implementations: (i) scalability to host a growing number of distributed users and resources, (ii) compatibility with grid constraints, and (iii) resilience to stochastic power injections. After a complexity analysis, scalability of peer-topeer markets and the proposed negotiation mechanism to solve them is enhanced by three improvements reducing algorithmic and structural complexities. Feasibility of the peer-to-peer electricity market is eventually obtained with the use of network charges. Two approaches are proposed to handle these network charges. The first, exogenous, requires the system operator to provide them a priori before negotiations start. In the second, the system operator updates network charges endogenously at each iteration to better account for the current grid status. Finally, power forecasts of stochastic agents are taken in a more comprehensive way by the developpement of peer-to-peer market on both energy and capacities, used to restore power balance in case of misdipatch due to forecast errors

Повний текст джерелаManufacturing tasks required mechanical interaction with the environment or the object being manipulated. In constrained maneuvers, the interaction forces must be accommodated rather than resisted. It is compliant motion theory. A lot of methods have been suggested to solve these requirements. In the axis inherent in this research, energizing considerations are not taken into account in the global system which involves the robot and his environment during task execution. In this thesis, we modelize the interaction in terms of power waves flowing between the robot and the environment. After describing the couple robot environment as a Norton circuit, we use the Scattering approach to analyze the exchanged powers in the circuit then this approach is used to choose the best parameters of the controller which ensure the maximum transfer of average power from robot to environment. The impedance of robot is matched to the impedance of environment

Повний текст джерелаIn the robotics industrials applications we need more and more sophisticated tasks. The compliant motion control of robot in contact with the environment is an important research subject. The performances of such cinematically closed loop system are depending of the robot, the environment and the link interaction in function of the system energy exchanged. First we give an energetic point of view of the robot coupled with the environment in contact tasks. Indeed, the study of the used power is strongly useful all the more the robot and the environment have energetic stage (structural stiffness). Next we studied the stiffness of robot joints. In order to do this we put under the light the static stiffness of two different robot type: PUMA 560 and Adept One (SCARA). The power transfer from the power supply of the robot to the load (robot coupled to the environment) is analysed using the scattering power waves. The different parts of the system (robot, corrector-actuator and environment) are modeled in the impedance model, in order to define the power scattering matrix of the system. Now we can determine a power transfer coefficient between the source and the load and an ellipsoid of power transfer which can establish the control and regulation power optimal directions (major and minor axes). Finally, the simulations and the experiments on a tow axes SCARA robot in contact with the environment validate the optimal power transfer between source (power supply of the robot) and load (robot coupled to the environment). So we put into the light the interest of the power transfer and scattering approach in the study of the dynamic comportment of the linkage

Повний текст джерелаThe signals used in modern telecommunication systems are very complex in the sense that multicarrier signals, digitally modulated and spread spectrum signals are required. The main characteristic of these signals is their time variant envelope. To characterize the linearity of power amplifiers used in these systems, one of the criterions, which is essential today is the NPR (Noise Power Ratio). After the description of the means of power amplifier characterizations under CW and multicarrier operations as well as CAD tools, an in depth study of the multicarrier linearity factor used (the NPR) is undertaken. A design method for power amplifier in terms of linearity and consumption was developed. This method is based on the optimisation of a new specific figure of merit (C/(N+I)=f(Pdc/N) which directly integrates the total signal to noise ratio of the system in a joint optimization of consumption and NPR. A systematic study of the optimal loading impedance and the operation classes of amplifiers is performed. One shows the interest of taking into account load and source impedances at the 2nd harmonic. The new design methodology is applied to the realization of two amplifiers optimized in linearity and consumption. An experimental checking validates the successive steps of the design. A complete characterization on a NPR measurement set-up of the two produced amplifiers is presented
