Energy storage requirements for in-stream tidal generation on a limited capacity electricity grid

This study presents the modeling and analysis of an ESS (energy storage system) for a TEC (tidal energy converter) to be installed in the Bay of Fundy, Canada. The electricity distribution grid that services the region has a minimum annual electricity demand of 0.9 MW. Policy limits the installation of renewable electricity generators to 0.9 MW at this site. An existing 0.9 MW WEC (wind energy converter) occupies this capacity, inhibiting further installations. The use of an ESS enables the installation of a 0.5 MW TEC by ensuring the combined electricity output from WEC and TEC does not exceed 0.9 MW. The objective of this study is to model the system and determine the characteristics of the ESS capacity, power, and cyclic nature.
