Frequency is the most important parameter in the power system. For satisfactory operation of power system, the frequency should remain constant to its desired value. Almost all components used in the power system itself and electrical appliances are designed for a specific frequency. Some reasons of frequency deviation include: sudden load change (mismatch between supply and demand), faults and renewable energy integration in the grid system. To maintain the frequency in their desired value, traditionally generation side controllers are used. Due to their high operational cost, generation side controllers are not desirable by the power system operators. This research proposes a Demand Response (DR) technique as a promising alternate for the conventional generation controllers. It regulates the frequency by switching the responsive load ON or OFF. The proposed research operates in three different operational modes depending upon generation and load demand.  Mode 1:  When generation is greater than demand side load, the proposed system will switch ON the dummy load to regulate frequency, while in mode 2: Generation is less than demand side load, then the system will regulate frequency by switching OFF the non-critical load using ant colony method. In mode 3: Generation is considered to be equal to demand, in this mode there is no need to switch OFF or ON any load because frequency is already in a desired limit. By using DR program, the amount of reserved required can be reduced and hence it is more cost effective. In addition it provides a wide range of operating time frame, from a few seconds to few minutes.
