Algorithm for Priority Based Power Schedulingfor Residential Loads

Abstract

Residential usage of power and its management have become one of the most pressing global challenges in recent years as domestic electricity demand continues to rise. To accomplish the efficient use of power in smart residences, in which technology is used for making every domestic electronic appliance act “smart” or automated, concerns about exchange of information among devices and power management techniques within the houses are required to be addressed. Given that the user has a limited amount of electricity, this paper discusses a system that allows the user to prioritize home appliances based on their daily usage. The mobile application assists the user in determining the appliance's priority and number of working hours as well as check the real-time status of the appliances. Wi-Fi is used to communicate between the system and the mobile application. The mobile application also keeps track of the usage of electricity and informs the user accordingly. The algorithm schedules home appliances based on the priority selected by the user, allowing for more careful use of available electricity. It also aids in distributing the power among the residential loads in both scenarios i.e., in case of sufficient electricity and in case of limited electricity allowing the highest priority appliance to keep working by restricting the power usage of lower priority devices.
