摘要
插电式电动汽车(plug-in electric vehicles,PEV)近年来发展迅速,考虑PEV并网后的差异性需求,提出一种计及PEV需求差异的智能电网调度策略:根据需求差异将PEV分为无序充电PEV、可调度充电PEV和可调度充放电PEV,之后提出考虑高低功率调控差异性将可调度PEV分为高功率可调度PEV和低功率可调度PEV。最后,构建以智能电网运行成本最小和电动汽车支付费用最小的多目标优化调度模型。算例结果表明在考虑PEV差异性需求的情况下通过合理调度PEV可以有效提高可再生能源消纳能力、降低智能电网运行成本和PEV车主支付费用。
Plug-in electric vehicle(PEV) has developed rapidly in recent years. Taking discrepant demand of the grid connected PEV into account, a smart grid dispatching strategy considering the demand difference among various kinds of PEVs was proposed. Firstly, according to the demand difference the PEV was divided into unordered charge PEV, schedulable charge PEV and schedulable charge-discharge PEV. Secondly,it was brought forward that considering the difference between high-and low-power regulation and control the schedulable PEV was divided into high-power schedulable PEV and lowpower schedulable PEV. Finally, a multi-objective optimal dispatching model with the lowest operating cost of smart grid and the minimal paying fees for the electric vehicle was constructed. Results of calculating example show that considering the discrepant demand of the PEV the accommodation capability of renewable energy sources could be improved and the operating cost of smart grid as well as the paying fees of the owner for the PEV could be reduced by reasonable dispatching of the PEV.
