Problems solved by technology

The power generation system of the traditional microgrid is far away from other system layout areas such as energy storage and power distribution, and other systems such as energy storage and power distribution are arranged in civil engineering buildings. The layout of the power grid is relatively complex. The transportation, installation and site occupation of various equipment bring difficulties to the construction of the micro-grid. In addition, the power generated by the micro-grid causes a lot of loss during the transmission process, resulting in low efficiency of the micro-grid.

Abstract

The invention discloses a microgrid device, especially a wind-PV-ES (wind/photovoltaic/energy storage) integrated microgrid device, and belongs to the technical field of intelligent microgrids. The device comprises a power generation system, an energy storage system, a box body, an intelligent distribution system, and an energy management system. The power generation system depends on the box body and is disposed outside the box body. The energy storage system, the intelligent power distribution system and the energy management system are all disposed in the box body. The power generation system and the energy storage system are respectively electrically connected to the intelligent power distribution system, and the power generation system, the energy storage system and the intelligent power distribution system are respectively in communication connection with the energy management system. According to the invention, all equipment and the box body are integrated into one body, so the installation efficiency of the microgrid device is improved, there is no need of additional civil construction, and the transportation is safe and convenient. Moreover, the high cost of the early construction and later maintenance is reduced.

Description

technical field [0001] The invention relates to a micro-grid device, in particular to an integrated wind-solar-storage micro-grid device, belonging to the technical field of smart micro-grids. Background technique [0002] In the face of many disadvantages such as the uneven distribution of energy and power grid gradually shown in the large power grid, the increasingly complex power grid, the rapid development of load, the more constant power of the load characteristics, and the gradual increase in the proportion of external power receiving in the load center, the micro grid has broad potential. Its core function is to access distributed power sources such as wind power and solar energy, realize self-control, protection and management, realize two-way interaction with users, lead smart life, provide grid flexibility and security, and integrate with large power grids. To become an organic whole is a powerful supplement and effective support for the large power grid. The powe...
