Control solution for hybrid-flywheel energy storage plant

14 December 2015

Yokogawa Ireland, a branch office of the subsidiary Yokogawa United Kingdom, has delivered a control system for Europe’s first hybrid energy storage plant in Ireland. 

Schwungrad Energie has developed the hybrid power storage system in collaboration with the Department of Physics & Energy at the University of Limerick, and will work with the Irish transmissions system operator to connect the plant to the power grid as a demonstration project under its Smart Grid Programme.

It comprises two 160kW flywheels and valve regulated lead acid batteries. The plant will have a maximum import capacity of 400kVA and maximum export capacity of 422kVA when completed. The flywheel system can rapidly absorb short-term excess grid energy and generate energy as needed by grid operators. 

Yokogawa delivered the FA-M3V high-speed controller and the FAST/TOOLSTM SCADA software to monitor and control the amount of energy stored in the flywheels and the charging/discharging of the lead acid battery. In addition, it provided an Exaquantum plant information management system that allows Schwungrad Energie to historise and analyse plant data and enabling it to transform this data into usable information. The company was also responsible for the engineering, installation, and commissioning of these solutions.
