#7. Reference - KEPCO FR ESS
As a result of 1st year pilot project, ESS proved superior performance than conventional
power plant
• Better Efficiency
 Battery Capacity Efficiency:
92%
 Duty Cycle Efficiency:
over 98%
• Superior Response Time
 Guideline of PCS Response Time: 200msec
 Rated Output Delay Time(from 0 to 1MW for PCS): 15.6msec
 Specified Output Delay Time by Control Algorithm: 110msec
• Overall FR Efficiency of ESS
 Performance of single 500MW BESS is equivalent to 26 individual 500MW Thermal Power Plant

Editor's Notes

  1. 전력 시장은 그림과 같이 기본적으로 deregulated market이다. 그러나 완전한 deregulated는 아니어서 발전 시장은 개방되어 있지만 대부분 한전의 자회사가 점유하고 있고 완전경쟁이 아닌 CBP 시장이다. 소매 시장은 현실적으로 한전의 독점이다. 한전은 공기업이므로 전력 판매 가격이 정부로부터 규제를 받고 그러므로 전력 가격은 OECD 국가 중에서도 가장 낮은 편이다. 이러한 이유로 수요 증가율은 높은 편이다. 한전은 한국 내 발전, 송배전, 판매에 걸친 지배적 사업자로서 경영 효율성을 심각하게 고민하면서 또한 공기업으로서의 사회적 의무도 고려해야 한다. 이에 따라 신재생 발전, 에너지 효율화 등 다양한 신 에너지 사업을 추진하고 있는데 최근 가장 공격적으로 투자하고 있는 분야가 바로 ESS이다. 다음 장부터 볼 Case Study에서는 이러한 한전을 비롯하여 LG가 어떤 ESS 사업을 추진하고 있고, 그 사업이 한전 또는 발전사업자에게 주는 benefi이 어떤 것인지를 살펴 보도록 하겠다.
