摘要
随着我国大力发展绿色经济和推行节能减碳,在电气化铁路系统内考虑新能源和列车制动能量相互利用被不断关注.文中提出了一种考虑光伏和能量调度装置的电气化铁路储能运行调度方法,在传统牵引变电所内融入光伏,通过储能和能量调度装置相互配合,提高列车再生制动能量的利用率,减少电网向牵引供电系统输送的电能,同时加强了源荷间的供电可控性和灵活性.数值模拟仿真表明采用文中方法优化后,牵引供电系统向电网获取的电能减少了 2500 kWh,验证了所提方法的有效性.
Abstract
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.
