Analysis of regional energy composition changes in Korea during high temperature cases using EnergyPlus model simulation

As global warming and climate change intensify, electricity consumption is increasing every year, and extreme weather phenomena such as heat waves in particular are causing irregular energy consumption, which is adding serious difficulties to predicting and managing electricity supply. In 2022, during the heat wave period in Korea when temperatures approached 40 degrees Celsius, electricity demand surged, which put a great burden on the power grid, and there were repeated instances of unstable power supply. This situation carries the risk of causing an emergency such as a large-scale power outage.
This study aims to analyze the probability distribution of power consumption to analyze these problems more precisely and to suggest ways to improve power management.
The study analyzed the impact of various weather conditions and temperature changes on energy consumption using the EnergyPlus building energy model. The entire Korean Peninsula was divided into 425 grids at 0.25º intervals, and temperature and power data for each grid were constructed. Through this, the differences in energy consumption changes by region across the entire Korean Peninsula were reflected, providing basic data for more precise power management.
The results of this study will provide useful statistical information on regional energy consumption and contribute to establishing power management strategies to effectively respond to changes in energy demand due to climate change. In addition, the significance of this study is to provide practical assistance in increasing the accuracy of energy resource management through risk analysis according to future population movement and regional development.
