本文通过在停电事件中提供车辆到电网（V2G）方案，研究了停车场在提高可再生能源配电系统可靠性方面的作用。在这方面，市政停车场被视为分布式储能系统，在随机突发事件中，这些单元的可用能量量被概率建模用于可靠性研究。还引入了适当的随机模型来捕捉可再生能源的波动性和间歇性。此外，还讨论了在突发事件中采用的停电管理方案（OMS）对客户可靠性水平的影响。为此，提出了几种基于破产问题的管理系统，以便在系统发生故障时，将可用资源公平地分配给不同的微网/区段。在此基础上，建立了基于非序贯蒙特卡罗仿真方法的通用框架，用于评估应急V2G方案下的不同客户和系统可靠性指标。通过在测试系统上的实现验证了该框架的有效性，并给出了几个案例研究。结果表明，实现电动汽车停车场提供的V2G方案，并辅以适当的OMS，可以显著提高现代配电网的供电可靠性。
This paper investigates the role of parking lots in improving the reliability of renewable-based distribution systems, through provision of vehicle-to-grid (V2G) programs during outage events. In this regard, municipal parking decks are viewed as distributed energy storage systems and the amount of available energy from these units in random contingency events is probabilistically modeled for reliability studies. Appropriate stochastic models are also introduced to capture the volatility and intermittency of renewable sources. Moreover, it is discussed that how the adopted outage management scheme (OMS) in contingency events can affect the reliability level of customers. In response, several OMSs on the basis of bankruptcy problem are proposed to fairly distribute the available resources among different microgrids/sections, once a failure occurs in the system. Subsequently, a general framework based on the non-sequential Monte Carlo simulation method is developed to evaluate different customers and system reliability indices in presence of emergency V2G programs. The effectiveness of the proposed framework is validated through implementation on a test system and several case studies are presented. The results suggest that realization of V2G programs offered by EV parking lots, accompanied by an appropriate OMS, can significantly enhance the reliability of supply in modern distribution networks.
