Distributed Power Electronics Architectures for Photovoltaic Power Plants
In photovoltaics (PV), the big challenge is to built and maintain PV installations in a cost-efficient way. Cutting-down the cost of PV modules has improved the competitiveness of this renewable energy, but we are still very far away from what it is achievable.
Some of the present issues in conventional PV systems are related to: lack of scalability, large-impact of mismatch, inability to mitigate intermittency, and poor reliability of central inverters.
This project proposes as main objective the development of new, smart photovoltaic (PV) modules, which will address these issues. These new PV modules will be enhanced thanks to the use of power electronics converters that are integrated at submodule level in PV modules [1-3].
Enhanced PV modules will outperform current devices in terms of power delivery, immunity to changing conditions or mismatch, reliability, cost and durability, improving the capabilities of residential, commercial and utility-scale PV systems.
The candidate will be trained in the following areas. Experience is not required, but definitely a plus:
- PV systems characterization and modeling.
- Power conversion architectures.
- Power electronics converter design and fabrication.
- Magnetic devices design and fabrication.
