Abstract

The invention relates to a smart micro grid, and relates to the technical field of new energy. The smart micro grid comprises a control inversion system, an energy storage management system, a user end monitoring system, a solar energy collecting system converting solar energy into electric energy and a wind energy collecting system converting wind energy to electric energy; the energy storage management system stores the electric energy and supplies power to a DC load of a user; the user end monitoring system sends obtained DC and AC electric energy change information to the control inversionsystem; and the control inversion system controls the energy storage management system to supply power to the DC load of the user according to the DC electric energy change information, and accordingto the AC electric energy change information, changes DC converted by the solar energy collecting system and the wind energy collecting system into DC by inversion and supplies the AC to an AC load of the user and/or the power grid. Thus, influence on disturbance of the power grid and the user load is reduced greatly, and loss in the power transmission process can be reduced substantially.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to an intelligent microgrid. Background technique [0002] As the world's energy supply continues to be tense and people pay more and more attention to environmental issues, the rational development and utilization of renewable energy has become an important issue. The development and utilization of renewable energy is an important measure to increase the sustainable supply of energy, improve the energy structure, ensure energy security, and gradually restore the natural environment. It is very important for building a resource-saving and environment-friendly society and realizing comprehensive, coordinated and sustainable economic and social development. meaning. [0003] In recent years, renewable energy, especially solar and wind energy, has been vigorously developed in the field of power generation, such as photovoltaic power generation in households, photovoltaic power g...
