Large integration of intermittent renewable energy generation causes the system frequency fluctuation. To solve this problem, more frequency control services will be required. Air conditioners in the commercial sector are one of the potential resources for demand side controllable load. This study proposes a model of coordinated LFC system that considers transient power consumption characteristics of commercial air conditioner and simulates system frequency fluctuation to analyze the effect of frequency fluctuation suppression by air conditioners power consumption control. To demonstrate the usefulness of controllable load, the reduction of inverter capacity in a battery energy storage system is evaluated.
