Intelligent energy storage machine and operating method thereof

Abstract

The invention provides an intelligent energy storage machine and an operating method thereof. The intelligent energy storage machine is used in a large scale, so that the electrical load of a power grid is relatively stable, the electrical load for the daytime and night is balanced, and the peak load shifting function is realized; and the energy storage machine comprises a miniature wind power and photovoltaic power generation input interface, and a new energy access power system is easily realized. The intelligent energy storage machine comprises a cabinet shell, a control system, an energy device and an energy storage device, wherein the energy device is used for providing energy for the load and comprises a solar energy device, a wind energy device and a mains supply; the electric energy generated by the solar energy device and the wind energy device is stored in the energy storage device; the energy storage device is an energy storage battery pack; the energy storage battery pack is used for storing the energy generated by the solar energy device and the wind energy device and the energy charged by the mains supply; and the control system comprises a wind and photovoltaic complementary controller, a grid-connected inverter, an off-grid inverter, a programmable logic controller (PLC), a battery management system and a bidirectional intelligent electric meter.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and relates to an intelligent energy storage machine and a working method thereof, especially to an intelligent energy storage machine and a working method thereof used in homes and public places. Background technique [0002] With the development of economy and modern industry, society's requirements for electric energy are increasing day by day, and power users have higher and higher requirements for power supply quality and power supply stability. The major power grids are delivering power to various industrial and commercial households with high loads, but the peak power consumption is more during the day, and the power consumption at night is basically reduced, which makes the peak-valley difference of the major power grids increasing day by day, but the power stations cannot stop working . Therefore, it is easy to cause waste of power resources at night. However, wind power a...
