Energy management and smart control of home appliances

Abstract

In the twenty-first century, there is a drastic depletion of non-renewable resources and a steady rise in greenhouse gas emission which causes global warming. In this case, it is wise to increase the use of renewable energy instead of non-renewable ones which will reduce the consumption of AC power. Sustainable energy sources like solar and wind are also used to control AC or DC loads, yet the execution is unsteady because of the ecological issues. Hence, it is essential to have a system with various input power sources which could provide power during a power-cut, grid failure and peak demand. It ensures better to maximum energy utilization and also results in a low electricity bill. This paper analyses the battery energy management which is crucial in the lives of the residential consumers by forming a system which can be operated both in grid connected and battery fed modes. To perform switching, it is mandatory to monitor both the input power sources and the loads simultaneously. When the loads are light loads and the charge of the battery is sufficient to drive the load, the loads are driven through the DC source. When the loads are heavy loads or the charge of the battery is less, the consumer cannot rely upon the DC source for driving the load. So, AC source is used to drive the loads. Depending upon the type of load, battery status and grid availability automatic switching takes place between the AC and the DC source.
