当分布式发电（DG），包括光伏（PV）电力系统的体积增加时，来自DG的反向功率流可能会引起问题。为了减少光伏发电系统的反向功率流，通过使用蓄电池进行能量管理有望成为一种解决方案。此外，与负荷控制相结合，预计将减少存储容量。在这项研究中，能源管理方法，通过使用的供应和需求接口（SDI），这是一个设备来控制DG，电池和负载，提出和方法的有效性进行了评估，通过仿真分析。仿真结果表明，所提出的能量管理方法可以有效地减少光伏发电系统的反向潮流，负载控制可以有效地减少反向潮流。还示出了防止从配电线路到输电线路的反向功率流所需的存储容量。
When the volume of distributed generation (DG), including photovoltaic (PV) power systems, is increased, reverse power flow from DG may cause problems. To reduce the reverse power flow from PV power systems, energy management by use of storage batteries is expected to be a solution. In addition, the combination with load control is expected to reduce the storage capacity. In this study, energy management methods by use of the Supply and Demand Interface (SDI), which is a device to control DG, batteries and loads, are proposed and the effectiveness of the methods are evaluated by simulation analyses. The simulation results show that the amount of reverse power flow from PV power systems is reduced by the proposed energy management methods, and the load control is effective in reducing the reverse power flow. The required storage capacity to prevent the reverse power flow from the distribution line to the transmission line is also shown.
