Abstract

Now-a-days, the consumption of fossil fuel is increasing day by day and the major proportion of it is consumed by vehicles and auto-mobiles. To decrease their dependability on fossil fuels, one solution is to electrify the vehicles by converting the fossil fuels based cars into electric vehicles (EVs) that will not only reduce dependability on fossil fuels but also play a key role in reducing the greenhouse effect. However, electrifying the vehicles increases the electrical load that has a significant impact on power system and upcoming smart grid which may eventually reduce the power system reliability. In this paper, the reliability and economic assessment of micro-grid consisting of renewables only, considering non-controllable loads as well as controllable EVs load, is investigated. In order to reduce the adverse effects of EVs on the micro-grid performance, dedicated G2V and V2G periods, taking social behavior into account, are proposed. Hourly load variations of IEEE-RTS-79 are used to examine the proposed model. Sensitivity analysis is well presented to analyze the impact of different V2G coordination levels on the micro-grid reliability.

V2G电动汽车协同下可再生微电网可靠性与经济性评价

如今，化石燃料的消耗日益增加，其中大部分消耗在汽车和汽车上。为了减少对化石燃料的依赖，一种解决方案是将基于化石燃料的汽车转换为电动汽车(ev)，这不仅降低了对化石燃料的依赖，而且在减少温室效应方面发挥了关键作用。然而，电动汽车增加了电力负荷，对电力系统和即将到来的智能电网产生重大影响，最终可能降低电力系统的可靠性。本文研究了仅由可再生能源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。为了减少电动汽车对微电网性能的不利影响，提出了考虑社会行为的专用G2V和V2G时段。使用IEEE-RTS-79的小时负荷变化来检验所提出的模型。采用敏感性分析方法分析不同V2G协调水平对微网可靠性的影响。
