Energy Storage Operation Scheduling of Electrified Railway Considering Photovoltaic and Energy Dispatching Device
With China vigorously developing green economy and promoting energy conservation and carbon reduction,the mutual utilization of new energy and train braking energy in electrified railway system has been paid more and more attention.In this paper,an electrified railway energy storage allowable scheduling method considering photovoltaic and energy scheduling device is proposed.By integrating photovoltaics into the traditional traction substation,the energy storage and energy dispatching devices cooperate with each other to improve the utilization rate of regenerative braking energy of trains and reduce the electric energy delivered by the grid to the traction power supply system.At the same time,the controllability and flexibility of power supply between source and charge are strengthened.The numerical simulation results show that after the optimization of the proposed method,the power obtained from the traction power supply system to the grid is reduced by 2 500 kWh,which verifies the effectiveness of the proposed method.
