Energy Saving in Distribution System using Internet of Things in Smart Grid environment.

Abstract

increase in energy consumption of home appliances is a growing problem in distribution system. The Demand Response (DR) strategy for reducing the energy usage is the key for any energy management system (EMS). In order to minimize the electricity consumption in domestic sector, the smart energy controller (SEC) with Internet of Things (IoT) is essential. In this paper, the smart energy controller is proposed for residential air conditioner (RAC) to save the energy and energy cost using new algorithm based on DR. Hardware prototype of SEC and software is designed to demonstrate the proposed the energy management system (EMS) for control the thermostat of RAC. The proposed DR algorithm is applied under three strategies in which the first strategy considers operation during one day of week from 12 pm to 12 am and the second strategy considers controlling of thermostat by sensing inside room temperature during 12 pm to 12 am of the day and third strategy considers operation of RAC by real time price (RTP) with several cases. The Experimental results of the proposed SEC are compared with each other strategy of EMS. The third strategy provides better results in terms of energy consumption and electricity cost.
