Methodology for the Automatic Generation of Optimization Models of Systems of Flexible Energy Resources

Energies
The integration of increasing shares of intermittent renewable energy necessitates flexibility in both energy generation and consumption. Typically, the operation of flexible energy resources is orchestrated through optimization models.

Balancing Energy Flexibilities Through Aggregation [PDF]

, 2014
One of the main goals of recent developments in the Smart Grid area is to increase the use of renewable energy sources. These sources are characterized by energy fluctuations that might lead to energy imbalances and congestions in the electricity grid. Exploiting inherent flexibilities, which exist in both energy production and consumption, is the key ...

Flexible substrate electrostatic energy harvester

Electronics Letters, 2010
Energy harvesting is attractive for powering wireless sensors, especially in applications such as body sensor networks and pervasive sensing, where power source replacement or recharging is impractical. A MEMS (micro-electro-mechanical systems) electrostatic harvesting device suitable for body motion has been reported previously, using a rolling rod as

Ab initio calculation of the $G$ peak intensity of graphene: Combined study of the laser and Fermi energy dependence and importance of quantum interference effects

, 2017
We present the results of a diagrammatic, fully ab initio calculation of the $G$ peak intensity of graphene. The flexibility and generality of our approach enables us to go beyond the previous analytical calculations in the low-energy regime.
