Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

To meet the net-zero emission target by 2050, Switzerland must install between 34 and 50 GW of distributed photovoltaic (PV). The inherent challenge with such an extensive integration of stochastic generation is to provide the flexibility for balancing sup ...

In the optic of providing guidelines for the optimal integration of renewable energy in a connected multi-energy context, this report presents EPFL - IPESE and EPFL - PV-lab’s common work on the initial assessment of Romande Energie (RE) demonstration site ...

Non-intrusive load monitoring (NILM) has been extensively researched over the last decade. The objective of NILM is to identify the power consumption of individual appliances and to detect when particular devices are on or off from measuring the power cons ...

The deployment of distributed photovoltaics (PV) in low-voltage networks may cause technical issues such as voltage rises, line ampacity violations, and transformer overloading for distribution system operators (DSOs). These problems may induce grid reinfo ...

A high share of distributed photovoltaic (PV) generation in low-voltage networks may lead to over-voltage, and line/transformer overloading. To mitigate these issues, we investigate how advanced electricity tariffs could ensure safe grid operation while en ...

Based on the analysis of the reference case, models developed at the PVLAB-EPFL and IPESEEPFL have been valued and improved to assess the impact of distributed generation and ancillary services on REel demonstrator. The models are used to evaluate solution ...

The increasing use of renewable energy is a deep going trend mainly supported by the sustained annual growth rate of solar photovoltaic, wind power and biogases. The expansion and evolution of the distribution grids is therefore a key issue to ensure a sec ...

There is a need by distribution system operators and power suppliers to propose ancillary services to enhanced grid operation allowing the optimal deployment of photovoltaic panels, cogeneration technologies and distributed storage. This deliverable theref ...
