Abstract

How to improve the comprehensive operation quality of the active distribution network is an urgent problem to be solved. In this paper, an optimal scheduling method for active distribution network considering electricity-heat-hydrogen load and dynamic reconfiguration is proposed. Firstly, the mathematical model of the active distribution network system was established, and the operation rules and tunable potential of electric vehicles, floor radiant heating/cooling systems, and hydrogen energy storage systems were analyzed. Secondly, considering the electrical-thermal-hydrogen load regulation and network reconstruction, the output of each subsystem and the switching state of the branch are taken as the decision variables, and a deterministic optimization scheduling model with the goal of reducing the operating cost, reducing the peak-to-valley difference and reducing pollutant gas is established. Then, the information gap decision theory is used to describe the source-load uncertainty, and a risk-averse scheduling model is established, so that the system has good robustness under the premise of ensuring a certain desired goal. Finally, based on the IEEE-33 node system, the scheduling schemes are compared and analyzed, and the effectiveness of the proposed method is verified.
