Parameter and Power Consumption Estimation of Residental Loads

Abstract

With the development of technology, the behavior of electrical devices has also changed. This makes it clear that the development of the load model and the correct identification of the devices are necessary. This study presents the development of the load model of residential loads such as incandescent lamp, Light Emitting Diode (LED) lamp, Liquid Crystal Monitor (LCD) and vacuum cleaner, and experimentally determining the coefficients of the polynomial load model and the exponential load model. Since the measurement parameters are easy to use and economical, PZEM-004T module was transferred to Excel with Arduino Uno and the coefficients and voltage reduction ratio of these load models were calculated in Matlab. It has been determined that both load models are suitable for the incandescent lamp and the vacuum cleaner. Estimated power consumption based on polynomial load model coefficients and actual power consumption results are obtained. According to these results, the estimated power in the incandescent lamp and vacuum cleaner is below the actual power; In the LED lamp and LCD monitor, the estimated power was found to be above the actual power.
