Abstract

The present invention belongs to the technical field of energy utilization, and discloses a highway chain type micro-grid system. The system comprises at least two micro-grid units. The micro-grid unit comprises DC buses, a micro-grid energy management module, a DC power generation module, a DC energy storage module, a DC charging pile and an electricity utilization device; the energy management unit is used for energy management and system protection; the DC charging pile is used for implementing DC fast charging on an electric vehicle; the electricity utilization device comprises DC LED street lights, advertising boards, cameras, and other transportation electricity utilization facilities; and the micro-grid units are adjacent to the highway, and the DC buses of the adjacent micro-grid units are connected by using a controllable connection device, so that the micro-grid units can operate independently and can also form a chain type micro-grid system for interconnection and mutual aid. According to the system provided by the present invention, the distributed new energy is used to realize self-sufficiency of electric energy; and the micro-grid units are evenly distributed, and theproblems of night lighting, the electric vehicle charging and endurance, and electricity utilization of various transportation facilities can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to an expressway chain microgrid system. Background technique [0002] With the development of society and economy, the public road network represented by expressways puts forward new requirements for power supply. First of all, the current main power load of expressways is street lamps. Due to the limitation of electricity budget or the difficulty of construction due to remote areas, most expressways with mileage are not equipped with street lamps, which poses a huge safety hazard. Secondly, the explosive growth of electric vehicles requires fast and large-capacity charging during driving, which poses a huge challenge to the construction, operation and maintenance of traditional power grids. In addition, traffic supervision equipment, communication equipment, billboards and other equipment and facilities are widely used on expressways and are widely distribu...
