Abstract

The invention provides a household multi-energy system, which is electrically connected with a power grid and household appliances. The household multi-energy system comprises a grid-connected inerter, an energy storing device, an off-grid inverter, a new energy generating module and a monitor, wherein the monitor is used for controlling the household multi-energy system to work in the working mode of the grid-connected inverter, the working mode of the off-grid inverter and the new energy generating mode in accordance with the state of the energy storing device, the power consumption state of the power grid and the new energy generating mode. The invention also provides a control method of the household multi-energy system. The energy storing device is added, so redundant electric energyof the new energy generating module can be stored, thus controlling the running of the multi-energy system reasonably in accordance with external conditions, improving the application level of the household multi-energy system effectively, and being beneficial to utilizing new energies reasonably, thereby being environmentally-friendly.

Description

technical field [0001] The invention relates to a family multi-energy system and a control method thereof. Background technique [0002] In recent years, the disadvantages of extensive use of non-renewable energy have become increasingly prominent. Energy shortage, environmental pollution, and greenhouse effect have forced people to pay attention to the development of new energy. The United States and other countries have also issued corresponding subsidy policies to encourage the use of new energy. In this context, a household multi-energy system that can distribute and utilize new energy such as solar wind energy in a large area has been developed. [0003] Most of the existing household multi-energy systems directly convert new energy sources such as solar energy into electric energy for use by household appliances through voltage transformation and stabilization devices. The use of new energy power supply in this way is restricted by factors such as weather, and the ge...
