Study of Spinning Reserve Setting Based on Local Wind/Solar Radiation Features in Unit Commitment

The wind and solar radiation of each location show distinct local features. This paper proposes a spinning reserve setting method that considers the local wind and solar radiation features. Through the statistics of local historical wind speed and solar radiation data, the wind and solar radiation transition matrices are established. Using the transition matrices, the power system's additional spinning reserves to compensate for wind and solar power fluctuations are set. The spinning reserves are then applied to the unit commitment calculations. A case study is performed on a 10-units system using the proposed method.
