Abstract

Electric vehicles (EVs) is an attractive solution to replace traditional petrol cars. The penetration of EVs posts a challenge for power systems since it would inevitably incur undesirable voltage drops. EV load shedding can be performed to regulate the grid voltage. The EV charging location is also an important factor when shifting the EV loads. This paper presents a new schedule-controlled framework with the aims of load shifting and voltage regulation to control EV charging operations for radial distribution networks. The new strategy consists of two stages, of which the initial phase performs EV scheduling in consideration of both EV constraints and power system limitations, and the second control layer checks for voltage violations with essential EV rescheduling. A voltage sensitivity analysis method is employed to alleviate the impacts of EV charging locations. The control scheme is evaluated through a modified standard IEEE 33 nodes test feeder. The results demonstrate the control scheme can effectively satisfy normal demands of EVs and achieve the voltage regulation purpose.
