This survey Paper is an ingathering of a comprehensive study of user comfort in smart grid. It is a compounding of different arenas of engineering like communication, electronics, management and power. Many techniques, like demand response, demand side management, real time pricing, time of use, home energy management, etc, are explained according to their role in Smart Homes (She). This is the short discussion about basic units of SH and their interrelationships. These techniques help to improve electricity consumption. In this survey paper, we focus on user comfort, reduction in bill payments, scheduling methods, necessary addition of renewable energy sources, etc. Thus, the user suffers minimum delay in appliance operation and retailer gets minimum peak-to-average ratio. This is a result of evolutionary enhancement of the previous electricity networks schemes towards an improved and maintainable energy schemes.
