【 摘 要 】
In order to efficiently utilize renewable energy and solve roadside fast charging of Electric Vehicle (EV) problem, a smart hybrid pole system is proposed in this paper, which integrated with renewable energy Street Lighting Pole (SLP) and EV charging. Besides, smart hybrid pole can also serve as the backup power for traffic lights. In this system, several renewable energy SLPs are coupled together by Direct Current (DC) micro-grid with storage battery, so it is suis for both DC fast charging and slow charging for EV. More importantly, the energy efficiency in this system can become much higher than alternating current (AC) EV charging system, because renewable energy power such as photovoltaic (PV), load and energy storage are all DC subsystem. Then for studying the suitable number in a group of smart hybrid pole, the group model of smart hybrid pole is presented. In addition, the hybrid pole energy storage system can be controlled by a cloud management platform, so it is convenient to make the decision to charge or discharge according to the different power prices. The smart hybrid pole solution is conducive to EV charging and the efficient application of renewable.
