Abstract
The Urban rail transit has become very popular, but the traditional power supply system of urban rail transit cannot accept the emerging green energy, for example, photovoltaic. At the same time, the free flow of energy cannot be realized. The energy router (ER) can perfectly realize the coordinated control of energy. According to the power supply characteristics of urban rail transit, this paper proposes a coordinated control strategy of energy router suitable for rail transit. Based on the state of charge of super capacitor, stabilize the voltage of 1500V input DC bus and 600V intermediate bus, At the same time, the energy consumption of train operation and the energy generated by braking are considered. A new control strategy of energy router is proposed, which realizes the coordinated control of photovoltaic, wind power, energy storage, AC load, the operation and braking of metro.
