Abstract:
This thesis addresses the subject of a hybrid photovoltaic/wind system connected with a battery
is designed to maximize energy efficiency by combining two renewable sources of electricity
production. The system uses both solar panels and wind turbines to capture natural energy from
the sun and wind. This energy is converted into electricity and stored in a battery for later use.
This work focuses on developing a method to control direct current (DC) bus voltage in a hybrid
multi-source power conversion (SCEM) system. This system integrates several renewable energy
sources. The proposed method uses converters (Chopper, Inverter) to efficiently manage and
stabilize the (DC) bus voltage, thus ensuring optimal integration of different renewable energy
sources to power a variable load.
The optimization of this system is based on several aspects:
1- Production management: An algorithm is implemented to optimize energy production
based on changing weather conditions. Control algorithms adjust the load distribution between
solar panels and wind turbines to maximize total energy production.
2- Efficient energy storage: The battery plays a crucial role in the system by storing excess
energy produced during peak production periods. This stored energy is then used to power loads
when there is little or no energy production, ensuring continuous power.
3- Variable load management: The system is designed to supply a variable load, which means
it must adapt to fluctuations in energy demand. This requires careful planning to properly size
the system and ensure stable power even when demand varies.
By combining these elements, the optimization of a hybrid photovoltaic/wind system with battery
makes it possible to maximize the use of renewable energies, reduce dependence on fossil fuels
and provides a stable and sustainable source of electricity.
