Load frequency control system with smart meter and controllable loads

The advances in the network technology and the emergence of the renewable energy as primary sources have changed the current view of the power system control. Smart meters will become a very important component in future power systems. In the event of an emergency the demand will play vital role in the stability of the power system. Conventionally, when a sudden generation loss occurs the generators have the responsibility to restore the system frequency. This process is expensive, comparably lengthy and increases the CO2 emissions. The smart meters can control the loads and hence secure the system stability, faster than the conventional generators. One of the important issues is to understand the operation of these emerging devices. In this paper, we present a Matlab/Simulink model for load frequency control system with demand-side control through the smart meter. From the simulation the demand-side control can improve the performance of the load frequency control system.
