This work is concerned with the analysis of vibro-impact responses observed in large-scale nonlinear geared systems. Emphasis laid on interactions between high-frequency internal excitation generated by meshing process, i.e. static transmission error and time-varying mesh stiffness, low-frequency external excitations. To this end, a three-dimensional finite element model pump equipped reverse s...

Since the penetration of photovoltaic systems in the electrical network is increasing, the need to register and model the contribution of these energy sources, in terms of generated disturbances, quality and amount of available power, is becoming a crucial issue for optimal management of grid. So, this paper, starting from data experimentally recorded on a medium scale photovoltaic system that ...

This paper presents a time-efficient modeling and simulation strategy for aggregated microinverters in large-scale photovoltaic systems. As photovoltaic microinverter systems are typically comprised of multiple power electronic converters, a suitable modeling and simulation strategy that can be used for rapid prototyping is required. Dynamic models incorporating switching action may induce sign...
