In a power system stabilization system for stabilizing a small-scale electric power system to which electric power generated by a rotating power generator is supplied, an electric water heater receives electric power from the electric power system and heats water, a system frequency measuring device measures system frequency of the electric power system, and a hot water controller increases the power consumption of the electric water heater when the system frequency exceeds a reference frequency, and decreases the power consumption of the electric water heater when the system frequency is less than the reference frequency.
