신재생 에너지 및 에너지 공유 활성화를 위한 잉여 에너지 활용 효과 분석

초록

Purpose: Energy use is expected to increase globally, and the use of renewable energy is growing as a solution. Increased use of renewable energy transforms building users into prosumers, and prosumers can form communities to share energy between buildings. In this study, propose methods to utilize the surplus energy generated between energy generation and energy consumption through renewable energy to promote renewable energy and energy sharing. Method: For analyzing the effectiveness of utilizing surplus energy, a virtual community was formed and charged for electricity using simulation. Based on the analysis results, methods for utilizing surplus energy were proposed through the features of KEPCO's electricity tariff system. The utilization methods include the reverse transmission system that sells surplus energy back to KEPCO, the use of the peak load of surplus energy using the hourly tariff system, sharing and using surplus energy with apartment buildings, and sharing surplus energy with buildings with the highest rates. Result: The study compared the rates of each method of utilizing surplus energy to the electricity tariff system. The results of the study showed that sharing and using surplus energy in apartment buildings was the most effective, followed by selling surplus energy back to KEPCO.
