Abstract

Solar power generation influenced by the weather. Using the weather forecast information, it is possible to predict the short-term solar power generation in the future. However, in limited circumstances such as islands or mountains, it can not be use weather forecast information by the disconnection of the network, it is impossible to use solar power generation prediction model using weather forecast. Therefore, in this paper, we propose a system that can predict the short-term solar power generation by using the information that can be collected by the system itself. We developed a short-term prediction model using the prior information of temperature and power generation amount to improve the accuracy of the prediction. We showed the usefulness of proposed prediction model by applying to actual solar power generation data.

태양광 발전량은 날씨에 큰 영향을 받는다. 기상 예보를 사용할 수 있는 환경이라면, 기상 예보 정보를 사용하여 미래의 태양광 발전량을 단기예측 할 수 있다. 하지만, 섬이나 산과 같이 네트워크의 단절에 의해 기상예보 정보를 사용할 수 없는 제한된 환경에서는 기상예보를 사용한 태양광 발전량 예측 모델을 사용할 수 없다. 따라서 본 논문에서는 시스템 자체적으로 수집할 수 있는 정보만을 이용하여 태양광 발전량을 단기 예측할 수 있는 시스템을 제안하였다. 예측의 정확도를 높이기 위하여 이전 온도정보와 발전량 정보를 이용하여 단기 예측모델을 생성하였다. 실험을 통하여 실데이터에 제안한 예측 모델을 적용하여 유용한 결과를 보였다.
