Abstract

The Home Energy Management System (HEMS) is a system for the efficient electric power consumption of each household. It can provide real-time electricity cost information according to electricity consumption, and households can immediately control their consumption of electricity. In this study, we analyzed the effects of the HEMS on the stability of demand for electric power. To do this, we analyzed the causal relationship between the amounts of electric power generation and consumption, from the system dynamics perspective. From the analysis, we found that in the current structure, the fluctuation of the quantity of demand became large due to the time delay in households recognizing the electric bill and adjusting their electric power consumption. However, when the HEMS was introduced, it could be seen that electric power demand remained stable since consumers could see their electricity bill in real-time and could manage their electricity consumption by themselves.

Highlights

In July and August of 2016, electric power consumption was the highest ever due to the heat wave in Korea
Despite the increase in power supply capacity in preparation for such a sudden power usage, the power reserve ratio in the case of maximum power demand declined to 8.5% in August 2016 from 16.5% in August 2015
The government is promoting the introduction of the HEMS (Home Energy Management System), a system that allows consumers to actively their control power usage

Summary

Introduction

In July and August of 2016, electric power consumption was the highest ever due to the heat wave in Korea. In order to prevent such a sudden blackout and maintain stable supply, the Korean government has prioritized projects to analyze electricity demand in real-time and lower the error rate by reducing the demand forecast error on the basis of it; and stabilizing the power reserve ratio by guiding households to consume electric power during the light load time. To this end, the government is promoting the introduction of the HEMS (Home Energy Management System), a system that allows consumers to actively their control power usage. We will identify what improvements are made when HEMS is introduced using system dynamics
