Abstract
Systems and methods for controlling an energy storage system to provide for delivery of multiple grid services are provided. Grid service requests can be categorized into a plurality of priority tiers. Power demands associated with the grid service requests can be allocated to enforce the prioritization scheme of the priority tiers. For instance, power demands associated with grid service requests in higher priority tiers can be given preference over power demands associated with grid service requests in lower priority tiers. Multiple grid service requests can be categorized within the same priority tier. In addition, the energy storage system can be controlled not only give priority to grid services requests categorized in the higher priority tiers, but also to manage the state of charge of the system to ensure that there is sufficient reserve capacity to meet power demands of the grid service requests categorized in the higher priority tiers.
