Energy storage offers the potential to provide a variety of services to the electricity grid, many of which are especially valuable to systems that rely upon high proportions of energy from intermittent renewable resources, like wind and solar. The economics of energy storage – especially lithium-ion based batteries – continues to improve at a dramatic rate, and project installations and manufacturing capacity continue to grow, promising on-going price and performance improvements.
The electricity grid is planned and operated at various time scales – typical planning horizons are thirty years- whereas operational frameworks for energy systems span from sub-seconds for certain ancillary services to years for the commitment of generators for resource adequacy (i.e. generation capacity).
This task focuses on promoting the effective integration of energy storage into the electricity system at all of these time scales, with particular attention paid to the software control systems required to integrate energy storage into the on-going operation of the grid. Further, integrating storage into electricity system planning and investigating the safety of battery systems intended for residential applications can facilitate the continued uptake in storage deployment.
The main objective of this task is to assess and compare different approaches to integrating energy storage into electricity system operation and planning. The analysis aims to identify both effective approaches to storage integration as well as the broader context – i.e. market design or planning processes – that enables storage to deliver significant value to the grid. While the primary focus is on studying and improving approaches to integrate storage into grid operations through control algorithms, additional attention is paid to how to integrate at best storage into various planning approaches and other technical issues (e.g., safety) that can accelerate storage deployment.
