Modeling of power consumption in a small microgrids

Abstract

Development of energy management systems and models of power grids are popular topics of many research projects. Unfortunately, quite often the behavioral tests with load data are not present. It is due to the difficulty of representing and collecting data about the power usage. To obtain such data it is required to deeply analyze operation lifecycle of certain devices and information about statistics of human behavior, as well as the patterns of people actions. Although many devices time profiles have been published, they lack characterization of variability of behavior and uncertainty. The paper presents some alternative ways to model power usage: probability profiles, rules and a mix of them. The purpose is to create a simulator for testing performance of energy management systems in a small microgrid.
