Investigation of Variability of Wind/Solar Resources Properties

Abstract

Renewable Energy Sources (RES) such as wind and solar energy depend on the climatic conditions, power grid and other comprehensive factors. Areas with sufficient RES also have large-scale wind power clusters and PV plants connected to the grid. In order to reduce the impact of fluctuating energy on power system, it is necessary to investigate variation of wind and solar energy resources in a region. This paper proposes an integrated method based on the xgboost model to study regional renewable energy resources. Characteristics of annual and monthly variation of aggregated powers in a large area are analyzed. The proposed method can be further used for reliability analysis and planning of intermittent power generation in regional grids.
