The Wind Energy Institute of Canada has installed a large-scale wind power and energy storage systems. The institute’s goal is to investigate the wind integration techniques and to increase understanding of the industry for energy storage systems. The objective of this project is to demonstrate and evaluate the capability of energy storage system for shifting wind energy over time and providing ancillary services. Multiple functions of energy storage systems can bring more value to them and justify their high capital costs. This project is in line with institute’s research objectives to show how energy storage systems can facilitate high wind power penetration into the electricity grid.
