Abstract

The penetration level of renewable energy resources such as wind and photovoltaic in power systems is increasing. The intermittent nature of such resources introduces challenges for frequency and voltage regulation. On the other hand, with increasing the presence of EVs in the future grids and their charging/discharging management can provide ancillary services, such as frequency regulation to the microgrid. In this paper, a new strategy for charging or discharging of EVs in the presence of renewable resources is proposed. In this strategy, with the application of day-ahead load and generation of renewables, a cost signal is obtained to manage EVs charging and discharging process. Based on this cost signal, EVs are encouraged to discharge their stored energy while the microgrid power reserve is low and they charge when the power reserve is high. Moreover, four modes are defined in a way that EVs respond to frequency deviations in both charging and discharging processes. The results show that the proposed strategy in decreasing the frequency deviations and improving the power reserve of the microgrid is successful.

包括可再生资源和电动汽车能源管理在内的微电网频率控制

风能、光伏等可再生能源在电力系统中的渗透水平不断提高。这种资源的间歇性给频率和电压调节带来了挑战。另一方面，随着未来电网中电动汽车的增加，其充放电管理可以为微电网提供频率调节等辅助服务。本文提出了一种可再生能源条件下电动汽车充放电的新策略。该策略通过应用日前负荷和可再生能源发电，获得成本信号来管理电动汽车充放电过程。基于这一成本信号，鼓励电动汽车在微网备用电量较低时放电，在备用电量较高时充电。此外，还定义了四种模式，以使电动汽车在充电和放电过程中对频率偏差做出响应。结果表明，所提出的策略在减小频率偏差和提高微电网电力储备方面是成功的。
