Description:
The aim of this work lies in investigating the grid frequency in the application of demand-side primary frequency control (PFC) with battery energy storage systems (BESS). In such an application, batteries participate in the PFC serving as energy buffer between their associated loads and the grid, and they are charged and discharged following the grid frequency conditions. The investigation focuses on the effect of PFC on the utilization of the battery in terms of its number of cycles. This includes studying the effects of the frequency dead-band on the battery charge/ discharge durations and the effects of droop settings on the charge/ discharge current rates. A case study of a 0.468 kWh battery pack is used to study the battery utilization under the reliability standards of PFC in the four interconnections of the North American grid. One-year line frequency data of the power system practically measured at Little Rock-AR is used in the analysis.
