An effective planning approach for integrated energy systems considering equipment operating characteristics

Abstract

Aiming at the accuracy of modeling in existing integrated energy system planning methods, a comprehensive energy system p lanning method that takes into account the actual operating efficiency of the system is proposed. First, the output model of various equipment units based on the basic structure of the integrated energy system is established. Then, based on the traditional energy hub model, a correction model for the work efficiency of energy equipment to construct an improved dynamic efficiency model of energy equipment is established. With the goal of minimizing the comprehensive cost of the integrated energy system, an integrated energy system planning operation model that takes into account the operating characteristics of the equipment is proposed. Finally, the planning method proposed in this paper is verified through simulation. The results show that: compared with the traditional planning method based on energy hubs, the method proposed in this paper improves the actual part-load performance of the system by improving the accuracy of energy coupling equipment, making the proposed planning model more reasonable and economical.
