ALPHEUS’ publication has been chosen among the best 10 papers of the whole RE Grid Integration Week 2020

The paper: The Contribution of Low‐head Pumped Hydro Storage to a successful Energy Transition (available here) presented at the virtual 19th Wind Integration Workshop (11 – 12 November 2020) was chosen among the best 10 papers of the whole RE Grid Integration Week 2020. The Wind Integration Workshop was designed for power system operators, transmission and […]

Update on ALPHEUS Work Package 3

In WP3, the Power Take-Off (PTO) and machine-side control are studied and designed. In the past year, good progress has been made on both subjects. For the shaft-driven Contra-Rotating Reversible Pump-Turbine (CR RPT), many possible PTO configurations are possible. These configurations were compared based on their influence on RPT and electric machine performance, as well […]

Deliverables Achieved: D2.1 and D2.2 of Work Package 2

D2.1 This report describes how the optimised initial down-scaled model design of the Shaft-Driven CounterRotating Pump-Turbine (SD-CRPT) in the ALPHEUS project was derived. A first design was made in prototype scale, according to the expected requirements of the final machines. The design was scaled to an appropriate model scale with respect to requirements from the […]

Publication: The Contribution of Low Head Pumped Hydro Storage to a Successful Energy Transition (PDF now available)

The pan-European power grid is experiencing an increasing penetration of Variable Renewable Energy (VRE). The fluctuating and non-dispatchable nature of VRE hinders them in providing the Ancillary Service (AS) needed for the reliability and stability of the grid. Today’s grid is reliant on synchronous generators. In case of sudden frequency deviations, the inertia of their […]

Upcoming Publication: The Contribution of Low-Head Pumped Hydro Storage to a Successful Energy Transition

Mr. Mohammed Qudaih, M.Sc., Research Assistant with the Working Group Energy Systems at Technische Universität Braunschweig’s (TUB) elenia Institute for High Voltage Technology and Power Systems will present a new paper on The Contribution of Low-Head Pumped Hydro Storage to a Successful Energy Transition at the 19th Wind Integration Workshop. The Wind Integration Workshop is […]

ALPHEUS: Augmenting Grid Stability Through Low Head Pumped Hydro Energy Utilization and Storage

ALPHEUS is a €5m project funded by the European Union’s Horizon 2020 program. In this post we explain the aims of ALPHEUS and each of the engineering components. Renewable energy, especially wind and solar, is essential for our global efforts to decarbonize and slow the rate of global warming. However, the current electricity grid is unable […]
