Details	Battery Energy Storage system (BESS) is prospective energy storage in Smart Grid and Hybrid Energy Storage System (HESS) composed of two different kinds of battery is also studied to achieve better performance and lower cost than single kind of BESS. The cost issue, however, has not been evaluated explicitly so far. On the other hand, BESS is studied and expected for ancillary service although HESS has not been applied to frequency control in power system. This paper focuses on HESS application to frequency control and its economic analysis. In this paper, the important battery characteristics in the application to power system are introduced and two kinds of HESS are evaluated in terms of their cost when they are applied to frequency control. In addition, the cost is analyzed for when HESS is used for Peak Shift as well as frequency control.
