A simple energy management system for a micro grid system using rule-based algorithm

Abstract

It is an interesting privilege if electricity consumers can use electrical energy more effectively and economically without sacrificing their needs and luxuries. With energy management system (EMS) in a smart home that supplied by grid and supported by alternative energy sources, more efficient, green-friendly, and economic energy can be obtained. To ensure this, it is a need to develop a reliable energy management algorithm for smart home. In this study, a simple energy management using Rule-Based Algorithm is proposed which could respond to user’s preferences, thus benefiting the user optimally. To meet those needs, an EMS using Rule-Based Algorithm for a grid-connected smart home, which supported with solar panel and battery is demonstrated. Also, in the proposed EMS, the state of charge (SOC) of battery will be controlled by the means of to protect the battery’s life cycle. Rule-Based Algorithm considered in this study has considered three main features: SOC of the battery, price-hourly and the load demand. The proposed system is simulated using Arduino IDE and Proteus Design Suite Software, before validated by a simple prototype to prove the rules functionality. From the results, it has shown that the proposed algorithm able to switch the grid, solar and battery sources well, besides offering lower energy bills without forfeiting their desires.
