신재생에너지 전원이 피크타임 전력 공급에 미치는 영향

Abstract

구조개편 이후 전력수급기본계획은 사업자의 자율의향을 토대로 수립되고 있으며, 다양한 신·재생에너지 발전소들이 본격적으로 전력시장에 진입하고 건설의향을 제출함에 따라, 신·재생에너지에 대한 수급기본계획 반영 방안 연구가 * 연구에 도움을 주신 손양훈, 박종배 교수, 그리고 대학원생 하정우 씨께 감사드린다.

With the concern of the potential problems which can be observed in terms of the power supply of renewable energies, we need to analyze the impact of additional power generation capacities of renewable energy sources on peak load. Each renewable energy sources are dependent upon wind speed, solar radiation, head differences caused by lunar calendar. Considering that these exogenous renewable energy sources follow their own stochastic distributions, we analyze the probability distribution of the impact of each renewable energy power supply on peak load. As a conclusion, we note that traditional tools used for the analysis of power supply such as capacity factors are no longer appropriate for the analysis of renewable energy sources in that perspective.
