Abstract

A low-carbon economic dispatch strategy considering the correlation of wind-solar and flexible carbon capture is proposed to tackle the challenges of large-scale renewable energy integration. First of all, the wind-solar correlation is comprehensively considered through kernel density estimation and Copula theory. Secondly, the carbon capture power plants with flexible operation mode is analyzed and demonstrated in terms of energy transfer characteristics and peak-shaving flexibility. Ultimately, a low-carbon economic scheduling model is built with the goal of minimizing comprehensive cost considering the difference in carbon emission benchmarks before and after plant modifications. The scenario-based approach is used to capture the stochastic nature of wind-solar generation, and the CPLEX solver is employed for optimization. The results certify that taking the correlation of wind-solar and flexible carbon capture into account in the dispatch process can simultaneously enhance system economic efficiency, low-carbon performance, and improve the wind-solar energy absorption capability.
