Introduction of new modeling for the provision of frequency regulation that allows direct/opposite reserves to be allocated in four modes of operation, hence reaching higher revenues by utilizing more reserves.
In markets that do provide regulatory support, such as the PJM and California markets in the United States, energy storage is more likely to be adopted than in those that do not. In most markets, policies and incentives fail to optimize energy-storage deployment.
Swinerton’s Mira Loma, California, energy storage project. In many regions, storage projects may be able to sell “ancillary services” in addition to energy or capacity either to transmission owners or to regional grid operators.
This approach enables the allocation of more frequency reserves by utilizing the energy products of the day-ahead market as reserves. The proposed approach achieved 22.8% higher annual profits in the joint energy and reserve markets (DA + FCR), allocating 10.2% more FCR reserves annually compared to existing models in the literature.
This utilization increases profits for both wholesale energy and frequency reserve, as it allows the ESS to allocate more energy products that act as reserves for FCR services. Every year, this increased allocation leads to a higher total annual FCR reserve by 10.2% and, consequently, greater activation of energy for FCR services.
The model shows that it is already profitable to provide energy-storage solutions to a subset of commercial customers in each of the four most important applications—demand-charge management, grid-scale renewable power, small-scale solar-plus storage, and frequency regulation.
