Abstract

The invention discloses a power utilization microgrid power distribution method. The real-time power transmission and power supply information and power utilization state information of a power distribution network are collected; a power distribution network computer network is accessed; various power information processing is performed on a cloud platform; household necessary electricity for residents is ensured on the basis of guaranteeing the power grid power supply performance according to intelligent power distribution management for priorities and power utilization characteristic parameters; meanwhile, in-time and effective information service is supplied to power grid running operation management administrators and power consumers; when the power distribution network is in fault, a fault processing program is started to execute fault positioning, fault isolation and microgrid recovery according to telemeasuring data and remote signaling data transmitted from FTU and by combination of fault information of a relay protection signal and a switch trip signal of a transformer substation. According to the power utilization microgrid power distribution method, rapid fault isolation and fault recovery power supply are realized; and meanwhile, the power supply reliability is improved, the fault recovery capability of the power distribution network is improved, and the economical efficiency is ensured as a whole while the security is guaranteed.

Description

technical field [0001] The invention relates to the technical field of microgrids, in particular to a power distribution method for power consumption microgrids. Background technique [0002] Microgrid is a concept relative to the traditional large power grid. It refers to a network composed of multiple distributed power sources and their related loads according to a certain topology, and is connected to the conventional power grid through static switches. Micro-grid (micro-grid) refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads, monitoring and protection devices. An autonomous system for management and management, which can operate in parallel with the external grid or in isolation. It is an important part of smart grid. [0003] According to the requirements of the "Twelfth Five-Year Special Plan for Smart Grid Major Science and Technology Industrialization Pr...
