I delivered the talk "Increasing energy storage capacity of hydropower plants: a perspective on quick ramping rates" at the workshop "The role of storage capacity of hydropower plants" organized by the PEN@Hydropower association. Thanks Elena (Dr. Vagnoni, EPFL) for the invitation!.
Welcome, Plouton Grammatikos, in my group!
Welcome to visiting student Florent Gerbal from University of Poiter, working with me for his internship.
Horizon 2020 project STOR-HY got funded! I will lead a work-package on ageing-aware control strategies for pumped-storage hydropower to increase its flexibility.
Welcome to the visiting master student Ali Mohamed from KTH/Univ of Lorraine working with me for his master thesis.
New project [STORE]. STORE is about to start! STORE aims to identify a functional energy storage infrastructure to achieve 100% production from renewables in Switzerland. The project, which I lead, includes 4 universities and 13 industries. It is financed by Innosuisse in the context of the Flagship Initiative.
New project [ResiNet]. In ResiNet (More resilient microgrids and grids), together with Prof Luca Haab (HEIA-FR) and Prof Stephan Kenzelmann (HES-SO Valais), we look at how to increase the resiliency of distribution grids under three perspectives: cybersecurity, control of zero-inertia grid, and cooperative distribution grids.

I started a new professional appointment at the University of Applied Science of Western Switzerland (HES-SO Valais-Wallis), where I am associate professor of electrical power systems.
I gave a seminar at the Waterloo Institute of Sustainable Energy (WISE) of the University of Waterloo (Canada) on model predictive control to reduce the fatigue in medium- and high-head hydropower plants' penstocks and coupling with battery energy storage systems.
New journal paper: "Stress-informed Control of Medium- and High-head Hydropower Plants to Reduce Penstock Fatigue", available here.
My research project on integrated energy systems has been funded with € 300'000 by Region Sud - Provence Alpes Cote Cote d'Azur and MINES ParisTech under the framework 'AAP Recherche'. It will support the creation of a beyond-state-of-the-art microgrid laboratory with multiple energy carriers at MINES ParisTech in Sophia Antipolis.
I will edit a special issue of IET together with Prof. Zechun Hu (Tsinghua University) on grid integration of electric vehicles. Call for papers will be out in early 2022.
Biswarup and I finalized a work on planning of charging infrastructure for electric vehicles and submitted it to IEEE Transactions on Smart Grid. The work is available here.
I presented at the wear-and-tear seminar of the H2020 project XFLEX-HYDRO our method for fatigue-informed control of medium- and high-head hydropower plant. Two journal papers covering all aspects of this subject (including using a battery system to reduce penstock stress), authored by Stefano and I, are currently out for revision. Preprints are preliminary available here and here.
Biswarup and Stefano presented two our papers at the conference ISGT 2021. One is on comparison of smart charging and vehicle-to-grid based on an extensible optimal power flow framework (more here); the other proposes guide vane-to-head and guide-vane-to-torque linearized models of hydropower plants for efficient model-based control (more here).
Stefano and I are developing an exciting demonstration of model predictive control (MPC) to reduce the mechanical stress in penstocks. We have set up and instrumented a 15-meter long, 2-inch diameter pipe to reproduce the "water hammer" effects happening in medium- and high-head hydropower plants when they provide regulating power to the power grid. By modeling hydraulic dynamics inside this pipe, we are capable of synthesizing a control law that avoids excessive forces on the pipe walls. In doing so, we increase the service life of this critical component while ensuring maximum flexibility for grid services — exciting stuff and probably an absolute worldwide prime. Stay tuned for more!
