Abstract

The invention discloses a microgrid system. The microgrid system comprises a cable bus, a municipal power main power, a new energy power generation system, an energy storage system, a load system, a main control switch, a load control switch and an energy storage control switch, wherein the cable bus is respectively connected with the municipal power main power, the new energy power generation system, the energy storage system and the load system in parallel, the municipal power main power is connected with the cable bus by virtue of the main control switch, the energy storage system is connected with the cable bus by virtue of the energy storage control switch, and the load control switch is connected with the cable bus in parallel. The energy system is arranged by using an energy storage technology, so that the power fluctuation can be balanced and inhibited, the stability of the power supply frequency can be maintained; and when the internal voltage of a power grid fluctuates, the energy storage system can also provide reactive compensation so as to maintain the stability of the voltage, the electric energy quality in the microgrid is improved, and the microgrid system has a popularization and application value.

Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to a micro-grid system. Background technique [0002] With the increasingly tense trend of energy in modern society, power grid has become a hot research topic at home and abroad in recent years. Obama proposed the concept of "Grid 2.0", the United States began to upgrade the old grid and applied for hundreds of related patents; Japan has fully launched distributed power generation and energy storage since the nuclear power crisis, and relevant departments have invested tens of billions of funds to support it; The plan regards smart grid and new energy power generation as national strategic development goals. [0003] The power 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. It is an autonomous system that can realize self-c...
