In Reunion Island, the objective of a decarbonized energy mix by 2030 is largely based on the massive integration of intermittent energies into the electricity grid. The growth of photovoltaic (PV) capacity, a direction encouraged by regional policy, relies on the swarming of hybrid conversion and storage systems on a domestic scale. With the proliferation of systems and the aging of the fleet, the risk of failures increases, which can lead to performance losses and profitability.
This project aims to implement innovative technical solutions to detect, isolate and identify defects that could lead to these failures. These solutions should improve the energy efficiency of PV systems by anticipating maintenance operations to limit the risk of failure.
Several barriers limit the large-scale deployment of hybrid production and storage systems, in particular their reliability and durability. Many faults may occur on one, or more, of the system components. If these faults are not quickly detected and identified, this can result in a loss of performance, instability or permanent degradation of the system.
Project duration : 2 years.
The objective of this project is to develop distributed technical solutions to analyze the hybrid systems health status – in particular PV systems installed in humid tropical environments. The developed solutions should allow to anticipate maintenance operations and to limit failure risks, taking into account weather and climate conditions simulated by a regional climate model at very high spatial resolution (< 1 km).
This objective will:
- Improve the adaptation of equipment to improve RUE (Rational Use of Energy)
- Participate in efforts to reduce energy dependency
- Promote the integration of intermittent energies into the electrical mix.
The innovative nature of the project lies in the use of regionalized meteorological and climatic variables using a regional climate model with very high spatial resolution ( 1 km) to supplement the available in situ electrical measurements. Validation of the developed modules will be carried out in the laboratory on emulated systems, driven by power signals, prior to installations tests.
DETECT allows to bring several elements of answers for a better energy efficiency:
- Quantification and localization of local energy resources (regionalization of the solar deposit using a regional climate model with high spatial resolution)
- Developing equipment instrumentation to improve REU (PV system diagnostics)
- Using ICT for the development of smart energy devices (real-time distributed diagnostics)
- Improve the mastery of a key technology by the actors of the territory (decision support for the planning of the maintenance of PV systems)
- Promote the integration of solar energy (reliability of PV systems)
- Strengthen the knowledge in the fields of renewable energy (aggregation of electrical and climatic data in a database)
