A novel smart meter for better control over devices including electric vehicles and to enable smart use of power in smart home

This paper provides a Smart Meter (SM) system for Smart Homes (SHs) which can measure the active energy consumption of each device installed in the building. This system also enables the user to control the devices of SH as per their requirements. It keeps full record of the rated current of each device and automatically switches off the devices when the current through it exceeds a safe limit. It also provides the information of the tariff plan of different utilities which are connected to the SH. This SM has an additional feature of automatic switching to the power supply with minimum tariff at any instant of time. Further, this SM can also regulate the charging facility for the Electric Vehicles (EVs). It has been verified that the EVs battery can be used to schedule the home devices and the proposed smart meter can handle all the scheduling scenarios of the appliances used in the home.
