Model Study on Optimal Configuration of Double-layer Capacity of Lithium-liquid Flow Battery Hybrid Energy Storage System
Year: 2025
Type: conference-paper
Abstract: Aiming at the complementary characteristics of lithium batteries and liquid-fluid batteries, this paper constructs a two-layer capacity optimisation configuration model for lithium-liquid-fluid battery hybrid energy storage system with the objective of minimising the comprehensive cost. The upper layer optimisation model aims at minimising the investment cost of the hybrid energy storage system, and the lower layer optimisation model aims at minimising the operating cost of the hybrid energy storage system. The model is solved by invoking the CPLEX toolbox. In the calculation example analysis, the wind and load data of a region in Qinghai Province are selected for model validation. Configuring the lithium-liquid-flow battery hybrid energy storage system can reduce the wind and light abandonment rate by up to 11.56%, and the comprehensive cost can be reduced by up to RMB 2,437,800,000, which verifies the validity of the constructed model.
