Abstract

The dissemination of energy management system (EMS), which uses renewable energies and energy storage system, is expanded for buildings. The very important point of EMS operation is to forecast a power load for buildings with estimating an accurate power load consumption pattern. Generally, existing methods of load forecasting have statistically and mathematically proposed the complicated and variety methodologies. But, the forecasting methods should quickly provide the results, and have to consider the convenience of operation to apply the management system. In particular, the methodology has to supply a environment that the operator can quickly be reflected the change factor of power load. This study draws the electrical load pattern for a building of the Korea Institute of Energy Research (KIER) through the precedent study about a forecasting methodology of electrical loads, and suggests the forecasting results for the same load by modifying a load pattern of the building using the same forecasting methodology as precedent study.

신재생에너지의 보급과 에너지 저장장치를 활용한 건물 에너지관리시스템(BEMS, building energy management system)의 보급이 확대되고 있다. 이러한 에너지관리시스템에서 매우 중요한 관리 대상은 정확한 부하 사용 패턴을 파악하여 건물의 전력 부하를 예측하는 것이다. 기존 전력부하의 예측방법론은 일반적으로 예측 정확도를 향상시키기 위해 복잡하고 다양한 통계적, 수리적 방법론을 제안하고 있다. 그러나 시스템의 적용을 위해서는 빠른 시간내에 예측결과의 제공이 가능하고 운영의 편의성이 고려되어야 하며, 특히 운영자가 전력부하의 변경요인을 신속하게 반영하기 위한 환경이 매우 중요하다. 따라서 본 논문에서는 전력부하의 예측 방법론에 대한 선행연구를 통해 한국에너지기술연구원 한 연구동의 전력부하 패턴을 도출하였고 이 절차를 그대로 활용하여 원내 건물에 전력부하 패턴을 수정하여 부하 예측을 수행한 결과를 제시한다.
