Energy storage systems are increasingly used in grids over the world. This growth is enabled by many facets that are continuously evolving: regulatory frameworks, standards, system controls, battery performance, consumer education and costs. At Evlo, we have contributed to facilitating adoption of energy storage systems for the past seven years. We have deployed systems in small and large grids, including in extreme weather locations, using our proprietary real-time controller partly developed with Simulink. In this presentation we will go over some key realizations to demonstrate how energy storage systems can contribute (1) to improve grid operations and (2) to facilitate increased usage of renewables.
