Abstract

Energy management is being highly regarded throughout the world. High-energy consumption in residential buildings is one of the dominant reasons of excessive energy consumption. There are many recent works on the demand-side management (DSM) and smart homes to keep control on electricity consumption. The paper is an intelligence to modify patterns, by proposing a time scheduling consumers, such that they can maintain their welfare while saving benefits from time varying tariffs; a model of household loads is proposed; constraints, including daily energy requirements and consumer preferences are considered in the framework, and the model is solved using mixed integer linear programming. The model is developed for three scenarios, and the results are compared: the 1^st scenario aims Peak Shaving; the 2^nd minimizes Electricity Cost, and the 3^rd one, which distinguishes this study from the other related works, is a combination of the 1^st and 2^nd Scenarios. Goal programming is applied to solve the 3^rd scenario. Finally, the best schedules for household loads are presented by analyzing power distribution curves and comparing results obtained by these scenarios. It is shown that for the case study of this paper with the implementation of 3^rd scenario, it is possible to gain 7% saving in the electricity cost without any increasing in the lowest peak power consumption.
