Regional energy interconnected distribution network system based on power routing technology

Abstract

The invention discloses a regional energy interconnected distribution network system based on a power routing technology. Regional power routers, variable-voltage power routers and branch power routers serving as core node devices are networked hierarchically to form a regional energy interconnected distribution network composed of an interconnected centralized control layer, a variable-voltage separate control layer and an interface extension layer which are distributed in a centralized manner and combined. The regional power routers are accessed into a traditional distribution network through a medium-voltage special line or a feed line to carry out AC-DC conversion to form medium-voltage AC and medium-voltage DC ring networks. The variable-voltage power routers are connected to medium-voltage AC and medium-voltage DC buses through medium-voltage AC and DC grid interfaces, and have the ability of AC-DC energy conversion and voltage transformation. AC and DC interfaces classified by function are formed on the low-voltage side, and the low-voltage AC and DC interfaces are extended through the branch power routers. The power routers are networked hierarchically and accessed into thetraditional distribution network. The permeability of distributed clean power generation can be further enhanced, and the requirements of different users for flexibility and power supply reliabilityare satisfied.

Description

technical field [0001] The invention belongs to the field of energy Internet and electrical technology, and more specifically relates to a regional energy interconnection distribution network system based on electric energy routing technology. Background technique [0002] In recent years, in order to alleviate the increasingly prominent energy, resource and environmental problems, a large number of distributed renewable energy power generation devices have been integrated into the power grid, making the traditional distribution network expand from the simple power supply function to the power generation function. In order to cope with the intermittent, decentralized and uncontrollable nature of distributed energy generation and improve the utilization rate of renewable energy, a large number of energy storage devices are added to the grid to buffer energy fluctuations. The power generation mode has shown the characteristics of centralized and distributed coexistence, and th...
