Abstract

This paper deals with bidirectional power flow based solar photovoltaic array powered electric vehicle (EV) charger with reactive power compensation. This configuration consists of a solar PV array that charges storage battery of EV and feeds the grid with remaining power simultaneously. For extracting maximum power, DC-DC boost converter is used and a three-phase voltage source converter (VSC) is used for the DC link voltage regulation. This arrangement provides extra opportunity to earn revenue at high electricity tariff by discharging energy to the grid. The proposed configuration is equally capable of reactive power balance. A brushless DC (BLDC) motor is used for ancillary purpose and is powered by battery charger under grid outage condition. The proposed charger is modelled and its performance is tested under different conditions of active and reactive power flow control in MATLAB/ Simpower system toolbox with the harmonic contents of grid current within 5% in every mode as per IEEE 519 standard. The charger is designed with three-phase, 230 V, 50 Hz utility grid.

基于太阳能光伏阵列的多功能电动汽车充电器的双向潮流控制

研究了一种基于双向潮流的无功补偿太阳能光伏电池阵电动汽车充电器。这种配置由太阳能光伏阵列组成，该阵列可以为电动汽车的蓄电池充电，同时将剩余的电力馈送电网。为了提取最大功率，使用DC-DC升压变换器，并使用三相电压源变换器(VSC)进行直流链路电压调节。这种安排提供了额外的机会，通过向电网排放能源来赚取高电价的收入。所建议的配置同样具有无功功率平衡的能力。辅助使用无刷直流(BLDC)电机，在电网中断情况下由电池充电器供电。根据IEEE 519标准，在MATLAB/ Simpower系统工具箱中对所设计的充电器进行了建模，并在电网电流谐波含量在5%以内的情况下，对其在不同有功和无功潮流控制条件下的性能进行了测试。该充电器设计为三相，230 V, 50 Hz公用电网。
