Having the features of safety, reliability, comfort, significant transport capacity, and relatively low time consumption, the electrified railroads are an effective way to solve traffic congestion. However, with the speedy progress of China’s electrified railway, power quality problems such as harmonics and negative sequences have received widespread attention, while more and more problems of regenerative braking energy not being effectively used in the traction power provision system have also emerged. Nowadays, traction substations are charged according to the two-part tariff, and the problem of ineffective use of regenerative braking energy will result in higher charges for the two-part tariff, which has a greater economic impact. The installation of railway power conditioner makes the issue of power quality effectively addressed, thus how to solve the power quality using the remaining regenerative braking energy, reducing the peak load to improve the economy has become the focus of national and international research. Due to the flexible charging and discharging characteristics of the energy storage device, it can make full use of the recycled braking electricity and reduce the peak load simultaneously. In light of the aforementioned background, this paper explores the control strategy and parameter adjustment of the power regulator for railway and energy storage system by using the data collected in an actual substation.

    The coordinated control strategy of battery and flywheel energy storage device is proposed for the real-time data of railroad locomotive traction load. By means of the new system of railway power regulator and energy storage device, the simulation model of actual working conditions is utilized to validate the strategy. The results indicate that the control strategy can perform well in power quality management and regenerative braking energy recovery. Meanwhile, when the peak load arrives, it can maximally and effectively reduce the peak load, thus not only managing the power quality but also further enhancing the economic returns.
