Abstract

a reflete ABSTRACT The advancement of electric mobility results in greater energy consumption of networks, considering this, microgrids with sustainable generation are presented as a solution for the supply of charging stations. However, not all locations in the world have high generation potential and financial incentives for this sector. Thus, this article presents the design of two microgrids with photovoltaic (PV) generation, BESS (Battery Energy Storage System) and green hydrogen, considering the same load, but different locations, namely the city of Recife in Brazil and Västerås in Sweden. . The objective is to assess the leveled cost of energy (LCOE) for both locations and compare it with the current cost of energy at the charging stations. The simulation was performed with HOMER Pro, in which the result showed that the Västerås microgrid has a power three times greater than the one dimensioned for Recife, which is reflected in the LCOE data. In Västerås, the leveled cost of energy is 4.25 Kr/kWh and in Recife, the cost was 2.67 Kr/kWh. In Brazil, the LCOE was 1.07 Kr/kWh below the current charging cost in Sweden.

为公共充电站供电的微电网pv / bess /绿色氢能源成本:巴西累西腓与vÄsterÅs -瑞典的比较研究

摘要:电动交通的进步导致了网络更大的能源消耗，考虑到这一点，具有可持续发电的微电网被提出作为充电站供应的解决方案。然而，并不是世界上所有的地方都有很高的发电潜力和财政激励。因此，本文提出了两个光伏发电微电网的设计，BESS(电池储能系统)和绿色氢，考虑相同的负荷，但不同的位置，即巴西的累西腓市和瑞典的Västerås。目的是评估这两个地点的水平能源成本(LCOE)，并将其与充电站当前的能源成本进行比较。利用HOMER Pro进行仿真，结果表明Västerås微电网的功率是累西腓一维微电网的3倍，这在LCOE数据中得到了体现。在Västerås，能源成本为4.25 Kr/kWh，在累西腓，成本为2.67 Kr/kWh。在巴西，LCOE比瑞典目前的充电成本低1.07克朗/千瓦时。
