Abstract

In order to improve clean energy consumption and flexible operation of multi energy coupling systems, while reducing the impact of source and load uncertainties on the system, this paper constructs a wind-photovoltaic-electric-heat-hydrogen integrated energy system (WPEHH-IES) including concentrating solar power, and proposes a two-stage robust optimization method with adjustable robustness for spatial polyhedral uncertainty sets. Based on the column-and-constraint generation (C&CG) algorithm, a two-stage three-layer min-max-min robust optimization model is decomposed into a one-layer min main problem and two-layer max-min subproblem. The structure of the two-layer subproblem is simplified by using the strong duality principle, and the optimal solution of the original problem is obtained by alternating the subproblem and the main problem. Finally, the effectiveness of the constructed model and solving algorithm, as well as the flexibility of the output of the multi energy coupling system, were verified through example analysis.
