초록

최근 들어 가정 내 태양광과 에너지저장시스템을 도입하여 에너지 자립도를 높이고자 하는 기술 개발이 활발히 이루어지고 있다. 낮에 생산된 전기를 에너지 저장 시스템에 충전해 두고 전기요금이 높을 때 사용함으로써 효율적인 에너지 관리를 수행할 수 있다. 국내에서는 아직까지 가정용 실시간 요금제가 이루어지고 있지 않지만 누진제 상의 일정 목표까지 전기 사용량을 낮출 수 있다. 가정 내 태양광을 도입하기 위해서는 전력 변환장치인 PCS를 필요로 한다. PCS는 직류로 생산된 전력을 교류로 변환하여 사용하고 에너지 저장 시스템의 충방전을 수행하도록 한다. 에너지 자립형 스마트 홈 시스템은 태양광, 에너지저장시스템에 대한 일반인들의 관심이 높아지면서 해외를 중심으로 시장이 형성되는 단계이다. 본 논문의 결과물은 실환경에 설치되어 검증을 수행하였으며 실시간 요금제를 가정하여 에너지 절감 효과를 분석하였다.

Research and development of energy self-consumption introducing photovoltaic and energy storage system at home is very active. This system can manage the home energy in which it charges the electricity generated during the day and uses it during high electricity bills. However, it not yet made up the residential real-time pricing in Korea but it can reduce electricity usage to a certain target on the progressive. In order to introduce the home photovoltaic, it requires PCS(Power Conditioning System). This converts the direct current into alternating current by the electricity generated and used to perform charging and discharging of the energy storage system. The market for self-consumption smart home system is currently increasing because the interests of the general public about solar power, energy storage systems increased. The result of this study is installed on the room environment and the effect was analyzed on the assumption of real-time pricing.
