Abstract

Energy storages are important to manage the high amount of electricity generation from renewable energy sources in microgrids. Furthermore, the economic benefits of battery energy storage (BESS) such as self-consumption maximization have proven its feasibility. In the present paper, a settlement area with photovoltaic and storage systems is investigated, where electrical loads including the heating load profile by using a heat pump. Different battery operation strategies have been analyzed and compared under consideration of the Brazilian white tariffs with the goal to decrease the grid supply. For this purpose, linear programming has been used. The results have been compared with the flat electricity tariffs to analyze the white tariffs effect on these types of systems. The result shows a significant increase in profit using white tariff. However, considering the investment cost of the battery, 5 years of payback time is required. Keywords—Microgrid, battery energy storage, direct usage, optimal storage operation, white tariff

考虑部门耦合和可再生能源的新结算区柔性电价最优储能运行

能源储存对于管理微电网中可再生能源的大量发电非常重要。此外，电池储能(BESS)的自耗最大化等经济效益也证明了其可行性。在本文中，研究了一个有光伏和储能系统的定居点，其中用电负荷包括使用热泵的热负荷剖面。在巴西以减少电网供应为目标的白色关税的情况下，分析和比较了不同的电池运行策略。为此，使用了线性规划。将结果与统一电价进行比较，分析白色电价对这类系统的影响。结果表明，使用白色关税可显著提高企业利润。但是考虑到电池的投资成本，需要5年的投资回收期。关键词:微电网，电池储能，直接利用，储能优化运行，白电价
