To provide a frequency controller which suppresses an increase in an operational cost and carbon-dioxide emissions while maintaining frequency stability.
The frequency controller 1 transmits an increase or decrease command of a generated electric power to generated LFC applicable generator groups 8, 10, 12 to each generator of the LFC generator groups 8, 10, 12 including a LFC applicable fuel battery group 12, based on information of the frequency of a power system 3 which is connected and constituted by a transmission electric line 15 performing power exchange with generator groups 7 to 13 including the LFC applicable fuel battery group 12 for generating the electric power and a load group 14 having a load 39 for consuming the electric power, information of a power flow flowing a line linking with another power system 5, and information of a power flow of the transmission electric line 15 in which the LFC applicable fuel battery group 12 is installed.
