초록
에너지 저장 시스템(energy storage system, ESS)은 발전설비에서 생산된 전력에너지를 저장하여 필요한 시점에 사용할 수 있도록 전기에너지를 화학적으로 저장하는 체계이다. 따라서 에너지 저장 시스템은 에너지 이용 효율향상, 전력공급 시스템의 안정화에 기여할 뿐 아니라, 이산화탄소의 감축 및 화석연료의 고갈문제에 직접 대응할 수 있게 한다. 이차전지인 납 축전지는 현재까지 가장 기술적으로 안정되어 있고, 경제적이며, 신뢰성이 있는 축전지 중 하나이다. 이에 본 연구에서는 납 축전지를 적용한 에너지 저장 시스템의 국내외 실증사례를 조사하여 사례별로 정리하여 관련 연구에 참고하고자 한다.
Energy storage system is an energy reservoir which can store the electrical energy produced by the power plant into the chemical energy at the time whenever it needs to use. Accordingly, the energy storage system can help to improve the energy utilization efficiency and the stabilization of the power supply system. In addition, it can cope with the issues of carbon dioxide reduction and depletion of fossil fuel. Lead-acid battery in the secondary battery fields is one of the most developed technologies. It is also economical, reliable storage device. Therefore, the instantiation case of energy storage system using lead-acid battery was investigated for the reference studies.
