Abstract

The invention relates to a power distribution system in a microgrid island environment, comprising a first power measuring module, a second power measuring module, a communication module and a control module; the first power measuring module is used for measuring first electric energy data of a user load at an initial moment and sending the first electric energy data to the control module through the communication module; the second power measuring module is used for measuring second electric energy data of a distributed power supply at the initial moment and sending the second electric energy data to the control module through the communication module; the control module is used for determining the power value of the distributed power supply at the initial moment according to the first electric energy data and the second electric energy data, comparing the power value of the distributed power supply and the preset power value of every user load and controlling the output power of the distributed power supply to every user load according to the comparing result.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a power distribution system in a microgrid island environment. Background technique [0002] With the development of social economy and the growth of energy consumption, traditional power generation can no longer meet the growth of social electricity consumption, and at the same time it is facing problems such as energy shortage, system aging, and environmental pollution. 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. Microgrid has the advantages of flexibility, high efficiency, environmental protection, and diverse energy sources. It is mainly a controllable unit composed of distributed power sources, loads, and energy storage systems. The proposal of th...
