Ensuring the reliability of power systems critically depends on maintaining a real-time balance between electricity generation and consumption. This task becomes increasingly complex with the growing integration of variable renewable energy sources such as solar and wind. In the case of Spain, where renewable energy penetration is high, generation fluctuations due to weather conditions create operational challenges. This increases the demand for operational reserves, especially online spinning reserves (SR) that can be deployed quickly. This study uses statistical methods to investigate the impact of solar and wind generation on SR requirements. A multiple linear regression analysis revealed a coefficient of determination (R2) of 0.76, indicating that changes in renewable energy output can explain 76% of the variability in spinning reserve needs. Furthermore, a correlation coefficient of 0.82 confirmed a strong positive relationship between renewable generation variability and reserve requirements. These findings highlight the necessity of incorporating renewable generation uncertainty into reserve planning. Traditional approaches that rely solely on load forecasting are no longer sufficient in systems with high renewable penetration. Instead, a more comprehensive planning strategy that considers demand variability and generation uncertainty is essential to ensure system security and operational flexibility.
