Abstract

The invention discloses a household micro-grid system capable of participating in power grid energy optimization configuration. The household micro-grid system comprises a DSP processor, a storage battery module, an external distributed power supply module, an electricity meter, an AC / AC, a load and a power grid, wherein the DSP processor is respectively connected with the storage battery module,the AC / AC and the power grid, and is used for carrying out communication deployment with the power grid, controlling the storage battery to feed to the power grid when the energy storage threshold value of the storage battery is exceeded, and controlling the storage battery to charge when the power utilization valley is reached, the storage battery module is connected with the distributed power supply module, the load, the DSP processor and the power grid, the storage battery module comprises a storage battery used for storing electric energy of the distributed power supply module, an electricity selling meter used for detecting the electric quantity transmitted by the storage battery to the power grid and a DC / AC used for converting direct current into alternating current. The household micro-grid system is advantaged in that power grid energy configuration can be optimized, and power supply reliability is improved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a household micro-grid system that can participate in optimal configuration of power grid energy. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads and monitoring and protection devices. Most of the existing household microgrid designs are simple applications of general factory or enterprise microgrids, without considering the actual situation of household electricity consumption. Most families in China live in residential buildings, there is not enough space to install a large number of distributed power sources, and the power generation capacity is limited, which affects the reliability of household microgrids. Therefore, it is not easy for Chinese household microgrids to separate from the power grid to realize the island ...
