【Abstract】 The new power system and smart grid energy storage technology are important measures to achieve "carbon reduction,emission reduction,energy conservation",and are also inevitable measures for developing green economy and clean energy. The article takes subway train energy dispatch and train braking energy recovery and storage as case studies. Firstly,analyze and consider the principles and structural characteristics of hybrid energy storage technology using super-capacitor banks and battery components. Secondly,improve the energy recovery rate of train braking,strengthen the controllability and flexibility of SOC charge dispatch,and provide safe operation guarantee and intelligent detection for the coordinated utilization and recovery of electrical energy. Finally,experiments and simulations showed that the use of hybrid energy storage technology to optimize train braking energy loss per hour reduced the unit mileage by 2 000 W,increased traction network voltage recovery rate by 15%,improved current transmission stability efficiency by 8%,and increased train electricity dispatch efficiency and SOC charging accuracy by about 10% and 12%,respectively. This verifies the effectiveness of the optimized hybrid energy storage scheme technology.更多还原
