The application of ESS (Energy Storage Systems) in
\r\nthe future grids has been the solution of the microgrid. However, high
\r\ninvestment costs necessitate accurate modeling and control strategy of
\r\nESS to justify its economic viability and further underutilization.
\r\nTherefore, the reasonable control strategy for ESS which is subjected
\r\nto generator and usage helps to curtail the cost of investment and
\r\noperation costs. The rated frequency in power system is decreased
\r\nwhen the load is increasing unexpectedly; hence the thermal power is
\r\noperated at the capacity of only its 95% for the Governor Free (GF) to
\r\nadjust the frequency as reserve (5%) in practice. The ESS can be
\r\nutilized with governor at the same time for the frequency response due
\r\nto characteristic of its fast response speed and moreover, the cost of
\r\nESS is declined rapidly to the reasonable price. This paper presents the
\r\nESS control strategy to extend usage of the ESS taken account into
\r\ngovernor’s ramp rate and reduce the governor’s intervention as well.
