Abstract

These days the consumption of fossil fuel is increasing substantially and the major proportion of it is consumed by transportation sector. So, electrification of vehicles is one way to minimize their dependence on fossil fuels which also plays a significant role in reducing the greenhouse effect. However, vehicles transformation enhances the electric load which has a significant impact on current power system and upcoming smart grid which may eventually affect the reliability. In this paper, the reliability and economic assessment of micro-grid consisting of renewables as well as diesel generators, considering non-controllable loads as well as controllable EVs load, is investigated. To further improve the reliability of micro-grid, dedicated G2V and V2G periods are considered. Solar irradiation, wind speed and hourly load data of Dammam region are used to examine the proposed model. Sensitivity analysis is well presented to analyze the impact of different combinations of renewable sources and diesel generators, different V2G coordination levels, storage efficiencies and charging/discharging rates on the micro-grid reliability.

V2G电动汽车协同微电网可靠性评价与经济性评价

近年来，化石燃料的消耗正在大幅增加，其中大部分是由运输部门消耗的。因此，汽车电气化是减少对化石燃料依赖的一种方法，这在减少温室效应方面也起着重要作用。然而，车辆改造增加了电力负荷，这对当前的电力系统和即将到来的智能电网产生了重大影响，最终可能影响其可靠性。本文研究了可再生能源和柴油发电机组成的微电网在考虑不可控制负荷和可控电动汽车负荷的情况下的可靠性和经济性评估。为了进一步提高微网的可靠性，考虑了专用的G2V和V2G时段。利用达曼地区的太阳辐照、风速和逐时负荷数据对模型进行了验证。通过灵敏度分析，分析了不同的可再生能源与柴油发电机组组合、不同的V2G协调水平、储能效率和充放电率对微电网可靠性的影响。
