Abstract

In this paper, the capacity optimization configuration of hybrid shared energy storage system based on multi-area integrated energy system is studied. Firstly, the overall architecture of multi-regional integrated energy system with hybrid shared energy storage is established, and the income approach and interaction mode of each subject are expounded. Secondly, an integrated demand response mechanism considering the load-side electricity-heat-cooling coupling conversion is proposed for the regional integrated energy system. On this basis, a bi-level optimal configuration model is proposed, in which the upper model aims at the optimal annual operating cost of the thermoelectric hybrid shared energy storage system, and the lower model aims at the optimal annual operating cost of the multi-regional integrated energy system. Meanwhile, aiming at the uncertainty of wind and solar output in the lower-level optimization model, it is transformed into a dynamic robust optimization problem with time-varying parameters, and a robust optimization over time algorithm based on problem characteristic change guidance （PCCG-ROOT） is proposed to solve the problem. The simulation results show that the proposed bi-level optimal configuration algorithm can reasonably configure the rated capacity and operating power of the hybrid shared energy storage system.
