Optimal sizing of hybrid energy storage system under multiple typical conditions of sources and loads

Year: 2024

Type: article

Abstract: Hybrid energy storage system (HESS) can support integrated energy system (IES) under multiple time scales. To address the diversity of new energy sources and loads, a multi-objective configuration frame for HESS is proposed under comprehensive source-load conditions. First, the IES operation model for minimizing the electricity purchase rate of IES and the HESS planning model for minimizing the levelised cost and the average reserve idle rate of HESS are established. Then, under the full condition scenarios based on APC, a HESS planning scheme is optimised by the NSGA-III and TOPSIS method. Finally, compared with single scene, the rated power and capacity of BESS differ by 5.46 times and 6.1 times, respectively. Based on full-condition scenarios, the proposed frame can integrate various operating conditions and effectively avoid the limitations of single conditions. The capacity of HESS accounts for 9.06% of new energy sources and BESS plays a dominant role at 74.82%.
