Frequency stability assessment of modern power systems: Models definition and parameters identification

Mario Paolone, Giacomo Piero Schiapparelli, Yihui Zuo

One of the fundamental concerns in the operation of modern power systems is the assessment of their frequency stability in case of inertia-reduction induced by the large share of power electronic interfaced resources. Within this context, the paper propose ...

Approximate Kron Reduction Methods for Electrical Networks With Applications to Plug-and-Play Control of AC Islanded Microgrids

Giancarlo Ferrari Trecate, Michele Tucci, Alessandro Floriduz

Kron reduction (KR) is a methodology for analyzing an electrical network by replacing it with a simpler circuit having less nodes but the same terminal behavior of voltages and currents at target vertices. Existing approaches to instantaneous KR, however, ...

Shaping light to influence occupants’ experience of space: a kinetic shading system with composite materials

Marilyne Andersen, Anastasios Vassilopoulos, Kynthia Chamilothori, Jan Wienold, Joëlle Baehr-Bruyère

Adaptive kinetic façades are systems capable of modifying their shape to optimize their behavior regarding real time outdoor and indoor conditions. They are typically evaluated based on quantifiable physical parameters such as illuminance levels, with litt ...

The Dynamic Emission Zone in Sandwich Polymer Light-Emitting Electrochemical Cells

Frank Nüesch, Balthasar Bluelle, Beat Ruhstaller, Roland Hany, Matthias Diethelm

In light-emitting electrochemical cells (LECs), the position of the emission zone (EZ) is not predefined via a multilayer architecture design, but governed by a complex motion of electrical and ionic charges. As a result of the evolution of doped charge tr ...

Reduced scale model testing for prediction of eigenfrequencies and hydro-acoustic resonances in hydropower plants operating in off-design conditions

François Avellan, Christophe Nicolet, Christian Landry, Sébastien Alligné, Joao Gomes Pereira Junior, Arthur Tristan Favrel

The massive penetration of the electrical network by renewable energy sources, such as wind and solar, pushes the operators to extend hydropower plant units operating range to meet the transmission system operator requirements. However, in off-design opera ...

Sim-to-real transfer reinforcement learning for control of thermal effects of an atmospheric pressure plasma jet

Berend Smit, Matthew David Witman

Applications of atmospheric pressure plasma jets (APPJs) present challenging feedback control problems due to the complexity of the plasma-substrate interactions. The plasma treatment of complex substrates is particularly sensitive to changes in the physic ...

Performance Assessment of Linearized OPF-based Distributed Real-time Predictive Control

Mario Paolone, Fabrizio Sossan

We consider the problem of controlling heteroge-neous controllable resources of a distribution network with the objective of achieving a certain power flow at the grid connection point while respecting local grid constraints. The problem is formulated as a ...

SCCER JA-RED - Detailed evaluation of the grid operation bottlenecks and load shifting potential for the reference system - Deliverable 1.2.2

Luc Girardin, Lionel Benjamin Bloch, Paul Michael Stadler, Jordan Holweger, Luise Middelhauve

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 ...

When and why performance goals predict exploitation behaviors: An achievement goal complex analysis of the selection function of assessment

Fabrizio Butera, Hamza Sehaqui, Kevin Fahrni, David Nguyen, Martin Jobin, Nicolas Sommet

We adopted an achievement goal complex framework (studying achievement goals and reasons connected to goals) to determine when and why performance goals predict exploitation of others' knowledge. We hypothesized that: (i) when selective assessment is used ...

Variations in elastic and electrical properties of crustal rocks with varying degree of microfracturation

Luis Felipe Orellana Espinoza, Marie Estelle Solange Violay, Lucas Xan Pimienta

This work aims at investigating the effect of varying degrees of microfracturing on the joint elastic and electrical transport properties of rocks. Different crustal rocks were subjected to Thermal Treatment, expected to induce microfracturing, up to diffe ...

Quantifying and Modeling the Impact of Interconnection Failures on the Electrical Performance of Crystalline Silicon Photovoltaic Modules

Christophe Ballif, Antonin Faes, Jacques Levrat, Matthieu Despeisse, Eleonora Annigoni, Alessandro Francesco Aldo Virtuani

We present an electrical model developed with LT SPICE that simulates the performance of a string of cells with disconnections in the electrical circuit. In a previous contribution, we quantified experimentally how the module performance is affected when o ...
