An unsupervised method for estimating the global horizontal irradiance from photovoltaic power measurements

Lorenzo Nespoli, Vasco Medici

The precise calculation of solar irradiance is pivotal for forecasting the electric power generated by PV plants. However, on-ground measurements are expensive and are generally not performed for small and medium-sized PV plants. Satellite-based services r ...

Decentralized Optimal Projected Control of PV Inverters in Residential Microgrids

Florian Dörfler, Pulkit Nahata

In this paper, we consider the problem of overvoltage arising in PV residential microgrids due to excessive power injection into the grid by the PV generators. We propose a decentralized optimal integral controller to curtail excess active power in order t ...

Mixed mode fracture properties of GFRP-adhesive interfaces based on video gauge and acoustic emission measurements from specimens with adherend fibres normal to the interfaces

Thomas Keller, Wei Sun, Wendel Michael Sebastian

Mixed-mode bending tests were performed on fifty-three GFRP-adhesive-GFRP specimens. In each specimen the pre-crack was located near the GFRP adherend with fibres normal to the GFRP-adhesive interface, so as to encourage crack propagation along this interf ...
