Abstract

The invention discloses an implementation method of a flexible intelligent direct current electric local area network electric power system, and relates to the field of an intelligent electric network and a direct current electric network. The implementation method provided by the invention ensures that the electric local area network electric power system has wider and more flexible regulation properties, is used for improving the operating efficiency, the reliability and the inclusiveness of the electric power system. According to the specified basic characters and demands of the electric system, and a basic framework and demands of a hardware system of an intelligent electric network management system as well as a framework and function demands of a software system of the intelligent electric network management system, an electric network regulation system is constructed, thus the intelligent power system is formed. The power system seems to build a stepped dynamic direct current electric power library, and the flexible regulation property thereof is beneficial for entering network of the distributed natural energy and other power generation equipment power electricity, thus effectively realizing the electric network storage of the electric power.

Description

1 technical field [0001] The invention relates to the fields of smart grids and direct current power grids, in particular to a method for realizing a flexible intelligent direct current power local area network power system. 2 background technology [0002] No matter at home or abroad, the current power grid is basically an AC network. Except for a few cases, the vast majority of user power grids are also AC networks. The power grid is mainly in the form of one-way power supply from a small number of power producers to users. [0003] Affected by many factors, the current operating efficiency of the AC power grid is low, and the adaptability of the power grid equipment is small. Some new power sources, such as wind power and solar power, are not easy to achieve power grid access. Power consumption units or residential quarters have established local power networks with power user units. In the current operating AC power grid, the user LAN is an important link that affects t...
