Abstract: With the transformation of the global energy structure and the continuous development of smart distribution network technology, the efficient utilization and optimal configuration of the power system has become the key to improve quality and efficiency and achieve green and sustainable development. Based on the existing power supply structure of the oil and gas transmission station of long distance pipelines in western China, the application advantages of the mobile energy storage device are analyzed, and its potential and economic value of improving the existing power system are evaluated. At the same time, in accordance with the characteristics of microgrid structure, a widely-used structure model with energy storage unit as the core is proposed, providing a useful reference for promoting energy allocation and efficient development in similar application scenarios.
