Development of a demonstration rig for providing primary frequency response through smart meters

A development of a rig that demonstrates a load control scheme which provides primary frequency response is reported. The rig uses a commercially available smart meter and remotely controlled smart sockets. A load controller implemented in a computer sends control signals to switch smart sockets on and off. The meter communicates with the computer using Modbus protocol through RS485 - RS232 protocol convertor. The controller sends load control signals to smart sockets via Home Area Network which communicates using ZWave protocol.
