Several aspects have been studied ranging from different electromechanical models through harvester forms maximizing performance to electrical circuits allowing an improvement of the harvesting energy. By spreading through the distribution electrical networks, the problem of harmonic pollution is becoming more and more worrying with the increasing use of electronic components and nonlinear loads, which leads to harmful consequences and therefore a malfunction of several devices sensitive to this kind of problems. Active power filtering is one of the most effective solutions to this problem. The contribution that brings this thesis, in the energy harvester and improvement field, consists to design a new optimal wind vibratory energy harvester using piezoelectric elements. The work of this thesis revolves around five objectives:
1. Design and experimental validation of a power generator based on piezoelectric
transduction and wind flow.
2. Development of an analytical model to predict the performances and explain the chosen
geometry of the piezoelectric wind energy harvester.
3. Development of an energy extraction circuit to maximize the harvested power by the
piezoelectric elements and adapt the generated voltages to a high level.
4. Design of a hybrid supercapacitors batteries system to store the harvested energy by the
wind piezoelectric generator and provide the power difference when an active power
imbalance occurs in the harvester system.
5. Development of an active filter compensation model based on piezoelectric harvester not only to mitigate the harmonic currents and voltages in the distribution electrical networks but also to compensate the reactive power on the source side.
In order to meet these objectives, at the beginning, we started with a reminder of the potential sources of harvested energy and the different conversion types including piezoelectric conversion and we have established a state of the art of the energy harvesting from piezoelectric elements. Then we presented theoretical notions of piezoelectricity followed by a detailed study of the piezoelectric phenomenon in order to use it in a vibratory energy harvesting structure and we have exposed a state of the art of piezoelectric generators with a macroscopic structure. Next, we have described bimetallic piezoelectric type structure as an example of application. After that, we presented the design, modeling, and the description of the proposed wind piezoelectric harvester, and we have established a literature review of the different generators models based on piezoelectric transduction and wind flow. In addition, the experimental validation of the piezoelectric generator model constituting our original contribution for that a large space was reserved for the presentation of the design process, fabrication and experimental assembly of the device after having developed a special analytical model. Besides, we showed how the extraction of the harvested energy can be conceived in order to maximize the power and adapt the generated voltages to the different electrical uses and how the storage of energy can be reached by a hybrid supercapacitors batteries system in a piezoelectric transduction mode. In the last step, we presented globally the problem of harmonics and the active filters as an effective solution. In addition, on the one hand, we applied a group of 8 identical PZT generators to the parallel active filter for current harmonics compensation, and on the other hand, we associated a group of 8 GEPZT to the series active filter to react against voltage harmonics and in the target to demonstrate its flexibility with piezoelectric systems.

The objective of this doctoral thesis is to optimize and improve the performance of the photovoltaic solar energy conversion chain connected to the grid in terms of energy quality injected to the electrical grid, price, and efficiency conversion. For this, we began our study by generalities on solar photovoltaic energy, photoelectric conversion; cell, panel, and photovoltaic field have been defined with theirs construction technologies, as well as the associated protections. Subsequently, we proceeded to the implementation of the maximum power point tracking MPPT procedure to maximize the photovoltaic energy produced, indeed, two control techniques are adopted: Perturb & observe and incremental conductance. The performances of these last two methods are tested in several rigorous meteorological conditions, to prove their efficiencies and robustness. Then, we have focused our studies to an application more representative to the final goal of the thesis, by introducing a power electronic interface (two-level voltage inverter) with the electrical grid and storage system to remedy the energy solar fluctuations. The results obtained clearly illustrate a very high performance in terms of stability and robustness against all strict scenarios imposed. Also, in order to optimize the conversion chain, a new DC-AC converter has been proposed: z source inverter. The advantage of this converter is increasing or decreasing the input voltage and ensure the energy conversion into a single stage (DC-AC). In addition, we have introduced another converter called quasi z source inverter similar to the z source inverter, in fact, it retains all advantages of the latter and offers other structural and technical performances because it can deliver a constant and continuous current at the converter input, and decreasing the values of the passive elements used, as well, its structure offers more possibility to integrating several storage technology. All these advantages make this converter very suitable for the power conditioning in a standalone photovoltaic system and grid connected installation. During the various simulation scenarios that we have imposed, all results obtained demonstrate the effectiveness of the converter and confirm the robustness, stability of all implemented algorithms.
