Abstract

Today, the plug-in electric vehicles (PEVs) are proposed to solve global warming problem which intensifying problem with the advantages of smokeless, soundless, and scentless. However, the uncontrolled charging PEVs impacts on voltage deviation, increasing of losses and decreasing of transformer life in the distribution system. The paper proposes PEVs charging model at residential houses by using load shaving method based on time of use rate (TOU) in the distribution system in Thailand. The model is considered under constraints of the power limitation in the transformer and phase power unbalancing. The results show that the load shaving method can control charging under the constraints whereas the off-peak load time and available time of PEVs are mismatched. Therefore, the total electric energy price with TOU rate is higher than the normal electric energy price. On the other hand, PEVs charging at off-peak time gets electric energy price and percent charging lower than uncontrolled off-peak time.

基于分时电价的插电式电动汽车配电网剃负荷充电研究——以泰国为例

如今，插电式电动汽车(pev)以其无烟、无声、无味的优点被提出来解决日益加剧的全球变暖问题。然而，在配电系统中，不受控制的充电会造成电压偏差、损耗增加和变压器寿命降低。本文在泰国的配电系统中，采用基于分时电价(TOU)的负荷调整方法，提出了pev在居民住宅的充电模式。该模型考虑了变压器功率限制和相功率不平衡的约束。结果表明，在pev的离峰负荷时间与可用时间不匹配的情况下，剃载方法可以在约束条件下控制充电。因此，有分时电价的总电价高于正常电价。另一方面，非高峰时段充电的电动汽车电价和充电率低于非控制的非高峰时段。
