论文摘要
插电式电动汽车（PEV）的高渗透可能会使公用事业资产（例如变压器）下载压力下降，从而导致其寿命减少。 PV和电池存储系统（BESS）价格的下降使它们成为缓解这种情况的可行解决方案。在本文中，研究了其最佳协调的经济方面，以评估变压器最热的斑点温度（HST）和生命损失。蒙特卡洛模拟用于在住宅络合物中提供PEVS负载的合成数据，并模拟其随机行为。对于负载，温度，能源价格和光伏生成，2018年获得了美国德克萨斯州大学城市城市城市的实际数据，并开发了一年的案例研究。结果说明了使用BES和PV在经济上有效的结果，并减轻分布变压器的生命丧失。
High penetration of plug-in electric vehicles (PEVs) can potentially put the utility assets such as transformer under overload stress causing decrease in their lifetime. The decrease in PV and battery energy storage system (BESS) prices has made them viable solutions to mitigate this situation. In this paper, the economic aspect of their optimal coordination is studied to assess transformer hottest spot temperature (HST) and loss of life. Monte Carlo simulation is employed to provide synthetic data of PEVs load in a residential complex and model their stochastic behavior. For load, temperature, energy price and PV generation, real data for City of College Station, Texas, USA in 2018 is acquired and a case study is developed for one year. The results illustrate using BESS and PV is economically effective and mitigates distribution transformer loss of life.
