Description: HES-SO is the University of Applied Sciences for Western Switzerland. Its Industrial Systems Institute located in Sion, Valais performs multidisciplinary research and development activities in three domains: development of instruments for energy, health and environmental purposes, renewable energy and smart grid.
Cyber-physical Smart Grid environment
- LV feeders
- lines emulated with discrete elements and real cables
- software controlled electonic converters
- software components emulating the behavior of entities connected to the grid (typically smart buildings)
- Energy Management System
PLC Test Bench
Description: A test infrastructure to measure EMC conducted disturbances and error rate on digital links
Description: GridLab Automation is a test bed for ICT (Information and Communication Technology) applied for grid control and management. Main topics are: smart metering, substation automation according to IEC 61850 / IEC 60870-5, and DER remote control and management (IEC 61850-90-7).
GridLab Local Storage
The storage facility of the GridLab is an application oriented lab, with the goal to test and implement control strategies around batteries. Studied subjects: control algorithms, self-consumption optimization, monitoring, system topology and power electronics for batteries.

GridLab Low Voltage
GridLab Small Hydro
A new universal test rig has been installed in the hydraulic laboratory to assess the hydraulic performances of different types of small-power axial and radial-axial turbines and/or pumps (less than 15 kW), valves as well as other components of hydraulic systems. Built on two floors, the closed-loop circuit is supplied by three recirculating multistage centrifugal pumps (with variable speed and a power of 5.5 kW each) connected in parallel. The three pumps can deliver a maximum discharge of 45 m3/h and a maximum pressure of 160 mWC. The pressurized reservoir placed downstream the test section allows simulating different implantation levels of the model and therefore recovering the cavitation performances. The operation of the test rig is controlled with an automatic system through a customized Labview® interface that allows for real-time measurement and display values of pumps speed, discharge, testing head, water temperature and Thoma number. The full capabilities of a NI cRIO 9074 are used to run an autonomous regulation system based on real-time measurements in order to keep constant the value of the desired parameters. The communication between the hydraulic test rig and further measurements/monitoring systems (e.g. testing model control system) is based on a wireless architecture. In addition, the test rig control system manages a dedicated cloud of variables and makes them available for client systems, and ensures safe data centralization and storage on model testing.
