Driven by economic and environmental concerns the solar power is today the most popular and affordable renewable electric energy resource. Power electronic inverters are one of the most important components of the solar power plants: they convert the DC power generated by the PV panels into useful AC power, to be injected into the electrical grid. However, current harmonics injected by PV inverters can result in abnormal conditions in the operation of the PV plant, including overheating of components (cables, power transformers, switchgear, etc.), nuisance tripping of circuit breakers, and harmonic resonance, among others. These issues negatively impact equipment reliability, asset life and operating costs, and consequently the overall operational performance of the PV generating system. Identification of these abnormal operating conditions is essential to implement the necessary corrective actions, and is the main objective of this study.

Tasks and duties entrusted to the student:

Modelling and simulation of power electronic converters. Field and laboratory tests and analysis. Identification of abnormal operating conditions of the PV plant.

Skills to be acquired or developed:

Advanced knowledge in power electronic solar converters and PV plants.

Compensation:

Erasmus + grant available depending on eligibility criteria of your home university
