Low-carbon Optimal Scheduling of Multi-energy Systems Based on A Multicollinearity-reduced Conditional Variational Autoencoder
Aiming at the source-load uncertainty problem under wind and solar power output scenarios,the paper proposes a low-carbon optimal scheduling method for multi-energy systems considering wind and solar power uncertainty. Firstly,considering the volatility of wind and solar power output,a scenario generation model for the wind and solar power uncertainty is constructed using a multicollinearity-reduced conditional variational autoencoder (MCLR-CVAE) optimized by a probability distance algorithm,accurately capturing the spatiotemporal variability of the wind and solar power output. Secondly,combining the spatiotemporal characteristics of demand response,a multi-energy system model is established. An integrated source-grid-load multi-energy system optimal scheduling model is formulated with the objective of minimizing the total system operating cost and environmental cost,and multiple scheduling sequence scenarios are designed for the scheduling resources. Finally,simulation results demonstrate that the proposed method can effectively achieve low-carbon optimal scheduling for multi-energy systems under wind and solar power uncertainty scenarios,and the scheduling sequence significantly impacts system performance.
