Operating storage with knowledge of key factors optimizes its application

It is relatively easy for someone to go with the lowest cost grid energy storage providers. However, the total cost of ownership of storage can be significantly reduced if longer life batteries and intelligent controls are integrated. Many owners and operators of storage are leaving money on the table because their controls systems are not considering all the key variables.

This talk will explain why simple control of an energy storage medium is not sufficient when designing and managing an energy storage system. We have shown that almost all ancillary services deployed on the grid (frequency response and frequency regulation) can be successfully and economically accomplished with fast response grid storage systems. But many of these do not have clear metrics to determine the balance of cost of energy (energy storage media lifetime) versus the gain in the payment for supplying the service. As a result, the definition of ‘optimization’ will vary amongst implementations.

The control system must balance among the storage application’s technical requirements, business criteria like service payments and energy costs, the energy storage system utilization, and overall system sizing. Intimate knowledge of the relationship of all aspects of the location, market dynamics, grid service application, cell chemistry, cycle life and calendar life, and system configuration is required to determine the control algorithm that provides the most optimized solution.

If one is to economically and efficiently deploy a grid-connected energy storage solution, they must either understand each component or assign it to someone who does. This talk will review variables at each level from cell chemistry, to battery configuration, to battery aggregation in racks, to automated coordination across and within the components, and finally to intelligent control algorithms.
