Abstract:
To explore the distributed energy station (DES), an important energy conversion link in the energy system, the characteristics of the station planning and multi-station multi-energy complementarity were studied, and the dual value attributes of "quantity" and "quality" of energy were taken into account, and the constraint of quantity and quality coordination was brought into the scope of DES planning. This paper proposes a multi-region electric-cold-thermal interconnection DES quantity and mass collaborative planning method. Firstly, the transmission model of the DES interconnected cold pipeline is established. Secondly, the DES integrated model, which considers electric-cold-thermal interconnection and new energy access, is established using an energy hub. After that, based on mixed integer linear programming, an exergy efficiency constraint was introduced to build a DES mass-quantity cooperative programming model for multi-region electric-cold-thermal interconnection with the lowest total cost as the optimization goal. Finally, an example is given to verify the rationality and feasibility of the programming model.
