Optimal Heat Production Pattern of CHP through Introducing of Alternative Energy Portfolio Standard in South Korea

국문 초록 (Abstract)

열병합발전(Combined Heat and Power, CHP)은 열과 전기를 동시에 생산하여 에너지 효율이 높다. 이러한 CHP의 에너지 절감 편익에 대해 인센티브를 제공하는 제도 중 하나가 APS(Alternative Energy Portfolio Standard)이다. APS는 CHP가 절감한 에너지량을 정량적으로 계산하여 인센티브를 지급하는 제도이다. 한국 정부가 국가 에너지 효율 개선 차원에서 APS 제도를 도입하기 위해서는 APS 제도 도입효과에 대한 정보가 필요하다. 따라서 본 연구는 APS 제도 도입의 효과를 조사하기 위해, 국내 도매 발전시장에 APS제도가 도입된다는 가정 하에 CHP의 열 생산패턴 변화와 이에 따른 연료 절감량 변화 효과를 검토하고자 한다. 이를 위해 국내에서 상업 운전 중인 CHP의 과거 운영실적과 설계자료를 이용하여 CHP 운전모델을 구축하고 이를 바탕으로 APS 도입 전후의 열 생산패턴과 연료 절감량을 계산하여 비교하였다. 그 결과 APS 제도가 도입됨에 따라 분석대상 830MW CHP를 기준으로 열 생산시간이 1년 동안 2009시간에서 423시간으로 단축되고, 연료 절감량 또한 46GWh에서 100GWh로 증가함을 확인할 수 있었다.

Combined heat and power (CHP) has a high energy efficiency as it produces heat and electricity at the same time. One of the policies providing incentives for the energy-saving benefits of the CHP system is the alternative energy portfolio standard (APS). The APS is a program that provides incentives for the amount of fuel saved by CHP. The South Korean government needs information to introduce APS to improve national energy efficiency. In order to investigate the effect of the APS introduction, this paper attempts to examine the changes in fuel savings caused by the change in the heat production pattern of the CHP system, under the assumption that the APS is introduced into South Korean wholesale electricity market. To this end, a CHP operation model is constructed based on the past operating performance of the CHP system in South Korea. After heat production patterns before and after the APS introduction are derived, the amount of fuel savings are computed and compared. It was found that the introduction of APS can reduce the heat producing hours of CHP from 2009 to 423 hours and increase fuel savings from 46 GWh to 100 GWh in terms of the single CHP with 830MW capacity.
