[Press release] LOLABAT project launches today: SuperGrid Institute leader of the work package “performance demonstration for stationary energy storage applications”

2021-08-11T17:23:05+02:00janvier 19th, 2021|Comuniqué de presse, Stabilisation & stockage|

The LOLABAT project has been awarded a Horizon 2020 program grant by the European Commission and was officially launched today, the 19th of January.

SuperGrid Institute at the forefront of technological innovation with its new HydroPHIL platform

2021-08-11T18:06:25+02:00novembre 30th, 2020|Stabilisation & stockage|

Our HydroPHIL platform, located on our Grenoble site, is designed to simulate the performance of hydroelectric dams within the power grid.

SuperGrid Institute is working towards the EU’s 32% renewable energy goal by contributing to XFLEX HYDRO

2021-08-11T17:23:30+02:00décembre 10th, 2019|Comuniqué de presse, Stabilisation & stockage|

The XFLEX HYDRO project was launched today, the 10th of December, during the United Nations climate change conference (COP25) in Madrid, Spain. This major project, led by a consortium of 19 members, will play an important role in helping the EU reach its target of producing 32% of its energy from renewable resources by 2030, by demonstrating how innovative hydropower technologies can ensure the safety and flexibility of the power system.

SuperGrid Institute’s “turbine type” readiness conclusions

2021-08-11T18:09:02+02:00décembre 2nd, 2019|Stabilisation & stockage|

How can we reduce the “S-Shaped” characteristics (stability) of a hydraulic turbine while maintaining its high performance? This spring, SuperGrid Institute completed several months of testing on different turbine designs for Pumped Storage Power Plants (PSPP). This promising and extensive research, which aims to improve power network services (supply security, flexibility, efficiency, etc.), has helped us better understand the physical phenomena and water flow that take place within turbines. It has also enabled us to corroborate our Computational Fluid Dynamics (CFD) simulation tools. A patent application was filed in September 2019 on this new technology.

TM1 test rig renovation

Why do we stil need experimental test-rigs in hydraulic sciences? We use extensively computatinal sciences to estiate performances of runners. Although it is accurate, Computatinal Fluid Dynamics (CFD) need to be checked with experimental data especially for cavitatin and transients. For that reason when prototype machines are greater than 5 MW or larger than 3 m of diameter it is mandatory to estiate on reduced scaled model with a great accuracy performances according to IEC 60193.

SGI participation to IAHR Conference

The International Association for Hydro-Environment Engineering and Research (IAHR), founded in 1935, is a worldwide independent organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. The 28th IAHR Symposium on Hydraulic Machinery and Systems took place in Grenoble on July.

CFD Investigation of Complex Phenomena in S-Shape Region of Reversible Pump-Turbine

2021-08-11T17:17:17+02:00octobre 19th, 2016|Publications, Stabilisation & stockage|

Pumped Storage Plants (PSP) using reversible pump-turbines offer the possibility to store large amounts of energy with high efficiency and at reasonable cost. For reversible high head pump-turbines, the characteristic curves exhibit an S-shape in the turbine, turbine break and reverse pump quadrants. This S-shape leads to unstable behavior of the turbine when coupling to the grid (for small guide vane opening) or to surge transient phenomena in case of emergency shutdown (for large guide vane opening).

The rise of variable speed Pump Storage Plant (PSP)

2021-08-11T18:11:15+02:00septembre 14th, 2016|Stabilisation & stockage|

Pumped Storage Plants (PSP) are the most reliable and well-known energy storage technology for high power applications. The needs of the future power network including DC transmission and intermittent power sources demand for fast responses from those storage plants. In order to face this new environment, the Variable Speed PSP (VarSpeed PSP) allows a faster response to the power grid.
