Abstract

The steady increase in energy demand for residential consumers requires an efficient energy management scheme. Utility organizations encourage household applicants to engage in residential energy management (REM) system. The utility’s primary goal is to reduce system peak load demand while consumer intends to reduce electricity bills. The benefits of REM can be enhanced with renewable energy sources (RESs), backup battery storage system (BBSS), and optimal power-sharing strategies. This paper aims to reduce energy usages and monetary cost for smart grid communities with an efficient home energy management scheme (HEMS). Normally, the residential consumer deals with numerous smart home appliances that have various operating time priorities depending on consumer preferences. In this paper, a cost-efficient power-sharing technique is developed which works based on priorities of appliances’ operating time. The home appliances are sorted on priority basis and the BBSS are charged and discharged based on the energy availability within the smart grid communities and real time energy pricing. The benefits of optimal power-sharing techniques with the RESs and BBSS are analyzed by taking three different scenarios which are simulated by C++ software package. Extensive case studies are carried out to validate the effectiveness of the proposed energy management scheme. It is demonstrated that the proposed method can save energy and reduce electricity cost up to 35% and 45% compared to the existing methods.

Summary

Introduction

A scare resource that needs to be efficiently utilized, is considered the most indispensable component in modern society. Energy losses are generally higher due to line losses increased by a factor of double [1]. These energy losses can be minimized by developing an efficient home energy management scheme (HEMS) that plays a crucial role in our daily life due to increasing energy demand [2]. Electricity consumers are not permitted to access the grid side mechanisms due to the high voltage grid and sophisticated device operation They can manipulate on energy consumption to minimize the peak demand while reducing electricity bills [6,7]
