One of the cases that pt. PLN (Persero) Load Control Service Unit (UP2B) is a system frequency that often rises and falls. The plant must be able to detect and respond quickly and precisely when such frequency changes occur. For this reason, frequency control is needed so that the system works stably, namely the primary controller (Free Governor) and the secondary controller (LFC / AGC). The use of AGC in Indonesia is still said to be new, compared to LFC which is generally used by existing plants in Indonesia. Because the control of AGC is still relatively new to the need for further development, therefore the purpose of this study is to find out how the response of coal-fired power plants that use AGC compared to LFC and see the control of the frequency response of plants using AGC and LFC at the same time at the time of disruption. To make a comparison, the way that is done is by collecting data on the response of plants using LFC and AGC. From the comparison carried out, it is known that plants that use LFC respond faster to changes in frequency than AGC, but to restore a stable state faster AGC compared to LFC, and AGC control is in the UP2B (Control Center) so that the economic dispatch will be taken into account.} }
