Energy management system for residential solar home system through load shifting

Abstract

Energy Management System (EMS) is a framework that allows energy consumers, such as industrial, commercial, residential and public sector organizations, to better control their energy consumption. It assists businesses in identifying and improving energy-saving technology, particularly those that may not necessitate a large upfront expenditure. This project proposes a EMS in residential solar home system (SHS) through load shifting method. This approach has been established to reduce the energy consumption during peak hours, by shifting away the demands during peak-time to the off-peak time. The decision on the switching algorithm is depending on the time-of-use tariff and electricity pricing. Therefore, each house load has been categorized into fix and transferable load which will be undergo in process of load shifting in order to reach a target of reducing daily electricity bill. Through this method, a modified load profile will be generated and this profile will be analyse further with each solar home system power generation of each house . Through this implementation of load shifting approach, major daily cost reduction of electricity could be achieve and it make the house residential less dependent towards the national power grid. Therefore, the objective of this project is met and EMS using load shifting method is carried out successfully.
