Review on Home Energy Management System (HEMS) Using FPGA

Abstract

 Now a days, energy saving is one of the most important issue for development of smart grid. The electric grid operation consists of vertical structure consisting of generation, transmission and distribution with the necessary infrastructure to ensure reliability, stability & efficiency. The hardware prototype of HEMS automatically switches the load between the battery & electric grid thereby reduces the energy consumption of the grid. The HEMS is implemented in SPARTAN 3 FPGA board, which in turn sends control signal to the relay connecting the load to the supply. The battery is solar energy charged battery which helps use of natural resource thereby managing the energy system. The FPGA controller checks for both demand limit & comfort level violations of the user. The use of solar operated battery inverter will help in energy management by using the natural energy source,sun to produce energy through solar panel. This will reduce the energy consumed by each household from the grid which in turn reduces the electricity cost.
