“…Further study is needed at system level to ensure the performance of an integrated system. In existing literature, charger research mainly focuses on three-phase converter control and the power flow is mostly unidirectional [16,17,18]. In [18], AC Voltage Sensorless control is studied for the control of a bridgeless power factor correction AC-DC converter.…”

“…Another research work [23] applies load frequency control strategy to achieve bi-directional power flow, however, the odd order current distortion is not considered. For the voltage and current control, conventional inner-current loop and outer-voltage loop controlled PWM converters are adopted in [16,22,24,25,26]. Encouragingly, in [27], a set of experimental results are completed with predictive current control method, this provides a good reference for the model-based study in this paper.…”

This paper studies the bi-directional power flow control between Plug-in Electric Vehicles (PEVs) and an electrical grid. A grid-tied charging system that enables both Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) charging/discharging is modeled using SimPowerSystems in Matlab/Simulink environment. A bi-directional AC-DC converter and a bi-directional DC-DC buck-boost converter are integrated to charge and discharge PEV batteries. For AC-DC converter control, Predictive Current Control (PCC) strategy is employed to enable grid current to reach a reference current after one modulation period. In addition, Phase Lock Loop (PLL) and a band-stop filter are designed to lock the grid voltage phase and reduce harmonics. Bi-directional power flow is realized by controlling the mode of the DC-DC converter. Simulation tests are conducted to evaluate the performance of this bi-directional charging system. The simulation results show that the integrated PCC, PLL, and band-stop filter can achieve fast dynamic response, low Total Harmonics Distortion (THD) of grid voltage and current, and unity power factor.

As the proliferation of electric vehicles continues to grow, it is becoming important to understand the impacts that electric vehicle charging will have on distribution assets. EV chargers are non-linear, multi-state loads. This manuscript presents a design method for the modeling of EV charging units using a VHDL-AMS simulation environment, per IEEE Standard 1076.1. Voltage and current data collected from in-service EV charging stations were used to create harmonic profiles of the EV charging units. From these profiles, generalized models for both Level 2 and Level 3 EV chargers were created. These models were validated within a larger system context using the IEEE 13 node test feeder. A VHDL-AMS tool has been created so distribution engineers may assess the impacts that EV chargers have on distribution assets. The tool may also be used to assist with the selection of transformers, conductors, and protection equipment.
