2024 International Conference on Renewable Energies and Smart Technologies (REST)
Year: 2024 | Conference Paper |
The future grid is expected to be mostly based on renewable energy plants, such as wind farms or solar plants, as well as hybrid power plants combining both technologies. As these technologies need a power inverter coupling, new dynamic interactions produced between each other arise, affecting the current stability of the grid. For that reason, there is an urgent need of developing simulation mode...Show More

Alejandro Gonzalez-Moreno;Javier Marcos;Iñigo De La Parra;Luis Marroyo

2022 IEEE 7th International Energy Conference (ENERGYCON)
Year: 2022 | Conference Paper |
This work analyzes the reduction of power generation in strategies that regulate the PV ramp-rate by using inverter limitation. Although the operating principle implies some energy production losses, not all these losses are necessary. Three different strategies were simulated using experimental 5-second data collected throughout a year at a 38.6 MW PV plant, and their energy losses were obtained ...Show More

This paper proposes a method for measuring the degradation rate of crystalline silicon PV modules at plant level in two different ways as a form of verification. As actual levels of degradation rate have been observed to be as low as 0.2%/a, the uncertainties make it difficult to measure this value accurately at plant level. However, despite the low value, it is still important to know the actual ...Show More
