This thesis was focused on proposing a HAPF, which is based on an APF and FC-TCR compensator to improve the energy quality of a wind turbine. The type of wind turbine used in this work is based on an SPMG with a full bridge converter. The converter consists of a diode rectifier, DC-DC boost converter, and VSC. The reason for choosing this type of wind turbine lies in the large harmonic distortion that occurs during the conversion of AC power into DC power. The thesis starts by providing a state of art of the energy quality issues that can occur in any electrical source, highlighting the standards of the most severe issues that should be respected. Then, the traditional and advanced solutions are discussed with a focus on the most used ones, providing some mathematical details and figures to show their performance, and providing their advantages and shortcomings. After that, some details of the control methods of the parallel APF and FC-TCR compensator are presented, some techniques of synchronization such as OLS technique and PLL are discussed and their performance is analyzed using different types of filters like the MAF, NLS approach, LPF, α- βCDSC operator, CCFs. Numerical results to show the performance and effectiveness of implementing these filters in the OLS technique and the PLL are presented. Moreover, some techniques of generating the reference compensating currents of the APF such as SRF algorithm and MPM are presented with details. Furthermore, some methods of generating
pulses such as PWM control, SVM control, hysteresis control, and MPC are discussed. Finally, the thesis ends with an application of the HAPF to mitigate the harmonics and improve the voltage drops of the aforementioned wind turbine. According to the results, it has
been demonstrated that in case of the FC-TCR compensator is well designed, with an acceptable attenuation factor, it can filter a high range of harmonics including the dominant ones and compensate for the voltage drops. However, in case the attenuation factor of the FCTCR compensator is not small enough, then the hybrid topology provides the best harmonic mitigation. Since, the APF is connected to only generate the dominant harmonics, its price decreases, and the possibility of applying this hybrid topology in medium voltage application increases.Note de contenu :

First, we presented the state of the art on wind energy and the conversion systems used (types of generators, most used configurations, etc ...). Then we exposed the mathematical models of each element of the wind turbine (the wind turbine and its command MPPT + the generator). Then we evaluated and examined two methods of vector control in power of the MADA in generator mode, the first to know: the direct command and the indirect command with the help of the correctors PI. According to the simulation results obtained, the indirect vector control with two cascade loops shows better performances for an invariant system. Finally, for nonlinear systems where with non-constant parameters, we applied the sliding mode control to control the active and reactive power with the use of an inverter controlled by the SVM technique to improve the electrical energy quality. to inject this energy into the electricity grid or we note that the simulation results show the reliability and robustness of this command which is given a good track of active stator power its reference with a negligible error.

Hybrid systems operating in isolated or autonomous mode in Algeria are not only intended to provide energy, but are also a tool for socio-economic development in rural areas. The intention of this thesis is to present an experimental study of an isolated hybrid system (photovoltaic and wind power with storage battery) installed in Constantine-Algeria, to meet the demand for energy used in public lighting (2000Wh / day for a test period, during the months of March and April 2018). And to meet a demand for a residential house (6000Wh / day, during the months of May, June and July 2018). This study examines a new strategy for how the MPPT charge controller (FLEX max60) controls the energy stored in solar batteries, by increasing the number of hours of absorption phase (ABS). In order to reduce the use of traditional sources. The control strategy was implemented on an experimental basis and the results presented showed the feasibility of the hybrid system, whatever the weather conditions. Therefore, maximum power point tracking (MPPT) has been proven to recharge efficiency, qualitatively and quantitatively in the MPPT controller (FLEX max60).
