[0006] However, the above research does not include research on the optimal configuration of the electric-gas multi-energy system, and there is no optimal configuration model for various devices in the electric-gas multi-energy storage system, such as energy storage batteries, P2G equipment, gas storage equipment, and gas pipelines. In addition, in the optimal configuration of multi-energy storage systems, the uncertainty of the type of energy consumption of users is not considered, and the feasibility of electric energy substitution after the addition of multi-energy storage systems is rarely discussed.
