An Advanced Planning To Enhance Energy Storage Utilization

Energy storage systems add flexibility to electrical grids. Flexibility is a key enabler for large-scale integration of renewable energy resources (e.g., wind- and solar-powered electricity). In order to for Canada to reach its clean energy goals, more of such resources are necessary. However, they are variable and non-controllable and thus, if integrated in large scales, grid operators need flexibility resources to manage them. Lithium-ion battery energy storage systems are gaining momentum in grid applications. However, they are still expensive, and thus, properly sizing them is essential in making a business case for these systems. Even though there are some tools already available in the industry for energy storage sizing, they often ignore many practical complexities, leading to sub-optimal planning recommendations. In this project, an advanced planning tool for Lithium-ion battery energy storage systems (LiBESS) for behind-the-meter grid applications will be designed. The tool is intended to integrate advanced models for the physical performance of the battery, account for uncertainty in a long-term planning horizon (e.g., long-term electrify price variations), and facilitate multi-stage planning to take advantage of modularity of LiBESS. BluWave-ai is the industrial partner in this project with both cash and in-kind support. The partner has identified the need for such a tool based on its ongoing experience and engagements with developing and commissioning hybrid renewable energy systems.
