Abstract
Energy storage systems are becoming increasing reliant upon for the balancing of the electrical grid with new frequency response services being introduced by system operators to exploit their potential. However, these storage systems have a finite energy storage capacity and therefore energy management strategies are required. In this paper a newly introduced frequency response service for the Great Britain electrical grid, Dynamic Regulation, is investigated to establish the control parameters and how these can be used for energy management. Two control methods are presented, the first being a base case for a standard response and the second, a dynamic control, exploiting the extremities of the allowable service envelope. Simulated results using real-world frequency data show that the latter control method can improve the availability of a battery energy storage system, potentially resulting in higher revenues and a reduction in the number equivalent full cycles.
