Can service stacking improve energy storage system integration?
Service stacking is a promising method to improve energy storage system integration. There are several interesting cases where service stacking is crucial. Frequency supportive services are the most common to add when expanding portfolios. There is no standard method to solve optimization of service portfolios.
Stackable Energy Storage Systems, or SESS, represent a cutting-edge paradigm in energy storage technology. At its core, SESS is a versatile and dynamic approach to accumulating electrical energy for later use. Unlike conventional energy storage systems that rely on monolithic designs, SESS adopts a modular concept.
From the reviewed literature the “optimality” approach varies frequently between the two cases with a majority of objective functions maximizing profit as main target. From the review it is found that the typical ESS used for service stacking is a 1C storage with approx. 1 MW/1 MWh rated power and energy capacities.
Does service stacking increase the utilization of storage units?
It can be concluded that service stacking is a promising method to implement for storage operators to increase the degree of utilization of storage units. It may also be concluded that the increased need for ancillary services increases the opportunity for storage units to participate in markets for energy and ancillary services.
There are several interesting cases where service stacking is crucial. Frequency supportive services are the most common to add when expanding portfolios. There is no standard method to solve optimization of service portfolios. The method is applicable to all storage technologies throughout the power system.
What are the requirements for energy storage systems?
Energy storage systems shall be installed in accordance with NFPA 70. Inverters shall be listed and labeled in accordance with UL 1741 or provided as part of the UL 9540 listing. Systems connected to the utility grid shall use inverters listed for utility interaction.
