Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of energy storage optimization, and particularly to a full-life cycle optimal configuration method, system, device and medium for a multi-time scale hybrid shared energy storage station. Background Art
[0002] With the rapid development of renewable energy, the importance of energy storage technology has become increasingly prominent. However, the high cost of current energy storage systems remains a major obstacle to widespread application. To solve this problem, the development of shared energy storage and mobile energy storage of electric vehicles has gradually become a new solution. Through shared energy storage, multiple users can jointly utilize energy storage devices, thereby sharing costs and improving economy. In addition, with the continuous increase in the grid connection ratio of renewable energy, the contradiction between power supply and demand imbalance at the seasonal scale has intensified, and the development of long-duration energy storage technology to enhance the stability of the energy system is an inevitable trend.
[0003] However, in the existing technical system, most of the shared energy storage considers electrochemical energy storage at a short time scale, lacking the consideration of the interaction between long-duration energy storage and short-duration energy storage. It is very important to consider the hybrid energy storage method of long time scale and short time scale under the background of high proportion of renewable energy. In terms of the configuration optimization of shared energy storage, only the provision of energy storage services by the shared energy storage station is considered, and the energy storage potential of electric vehicle mobile energy storage has not been further explored, nor the mutual cooperation mode between the two has been studied, and they are only analyzed and processed as isolated objects. At the same time, when optimizing and evaluating the environmental performance of shared energy storage, the current research is limited to the carbon emissions generated by consuming primary energy during the operation stage, ignoring the impact of emissions generated throughout the life cycle of building a shared energy storage station, from raw material acquisition, equipment production to operation and use, on the environment.
