IPv6-based intelligent power grid hierarchical address configuration method

Abstract

The invention discloses an IPv6-based intelligent power grid hierarchical address configuration method. A new IPv6-based addressing structure is arranged in the method. The method comprises the following steps that: when new user-side intelligent equipment is added into a power grid, the user-side intelligent equipment sends a routing request message so as to position a superior acquisition terminal of the user-side intelligent equipment; a superior acquisition terminal judges the number of subordinate acquisition terminals registered by the superior acquisition terminal at present; if the number is smaller than a first threshold value, the superior acquisition terminal sends a route reply message to the user side intelligent equipment; and the user-side intelligent equipment acquires theuser-side equipment ID of the user-side intelligent equipment and replaces the user-side equipment ID and the type ID in the address information of the superior acquisition terminal with the user-sideequipment ID and the type ID of the user-side intelligent equipment, and the replaced address information is the address of the user-side intelligent equipment. The address configuration method is more suitable for a dynamically layered intelligent power grid communication system and a topological form, and is beneficial to improving the expandability and the configuration flexibility of the network.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular to an IPv6-based smart grid layered address configuration method. Background technique [0002] With the continuous development of the smart grid, its informatization, automation, and interactive network characteristics are more prominent, and more and more IP-based information and communication technologies will be used in all aspects of the power system, including distribution automation and distributed power grid connection. , grid connection of power distribution and energy storage system, two-way interactive service, power consumption information collection, intelligent energy service, electric vehicle charging and discharging, intelligent measurement and other intelligent technology fields of power distribution and consumption. At the same time, with the rapid development of power Internet of Things technology Development, as well as the full life cycle management o...

Problems solved by technology

like figure 1 As shown, the general address format of IPv6 in the prior art is mainly a global unicast address structure, including a global routing prefix, subnet ID and interface ID, and this address structure allocates a large number of bits (64 bits) for the interface ID in the IPv6 address , does not meet the working scenario of the collection terminal and the smart device on the user side

However, if the network node itself is used to configure IPv6 addresses, the security and maintainability cannot be well guaranteed.

The smart grid adopts a dynamic layered system architecture, and its hierarchical structure can vary according to different application scenarios in different regions. The fixed hierarchical structure is not suitable for the smart grid
