Toward on Rolling Optimal Dispatch Strategy Considering Alert Mechanism for Antarctic Electricity-Hydrogen-Heat Integrated Energy System

Abstract

Renewable energy will be the important form of energy supply for future Antarctic scientific research station. This will complicate the dispatch of the Antarctic integrated energy system (IES), due to the harsh operation environment and diverse operation situation of the Antarctic system, especially for the problem of equipment outage caused by extreme weather. To cope with that, a rolling optimal dispatch method considering alert mechanism for Antarctic integrated energy system is proposed in this paper. First, the output of the proton exchange membrane fuel cell (PEMFC) is characterized by the feasible region and converted into a linear P-H-T model. By introducing the alert mechanism, a rolling optimal dispatch strategy is then established to ensure the security operation of the Antarctic integrated energy system. Furthermore, the normalized multiparametric disaggregation technology (NMDT) is presented to deal with the bilinear terms in dispatching formulation, in which a mixed-integer quadratically constrained programming (MIQCP) is converted into mixed integer linear programming (MILP). Finally, case study is verified on the actual Antarctic energy system. The results indicates that the proposed fuel cell P-H-T model can enhance the flexibility and economy of the operation system. Also the load shedding can be reduced during the emergency operation by developed optimal dispatch strategy, which improves the resilience of IES.
