Hybrid energy power supply energy storage system and energy storage method

Abstract

The invention discloses a hybrid energy power supply energy storage system and energy storage method. The hybrid energy power supply energy storage system comprises an energy storage main circuit anda plurality of power supply processing branch circuits connected with the energy storage main circuit, the energy storage main circuit comprises a connecting terminal, a direct-current charging device, an energy storage battery and a total storage device, the connecting terminal is connected with the energy storage battery through the direct-current charging device, the total storage device is connected between the connecting terminal and a grounding terminal, and the power supply processing branch circuits comprise input terminals, output terminals, first storage batteries, voltage detectiondevices, DC-DC (direct-current) conversion devices, second storage batteries and reverse prevention diodes. By the aid of a uniform energy storage scheme, the utilization rate of a hybrid energy powersupply energy storage device is increased, cost is reduced, and the service life of the energy storage device is prolonged.

Description

technical field [0001] The invention relates to a mixed energy power supply and energy storage system, and also relates to a power supply and energy storage method for the mixed energy. Background technique [0002] In order to save oil and coal resources and avoid environmental pollution, people have vigorously developed clean energy such as wind energy and solar energy in recent years. [0003] In the prior art, various clean energies are collected and stored separately, and energy storage devices need to be provided for different energy power supply systems. The utilization rate of the energy storage devices is low and the cost is high. Moreover, since the power supply output of wind energy, solar energy and other systems is greatly affected by natural conditions and is unstable, it is very easy to damage the energy storage equipment. Contents of the invention [0004] The present invention proposes a hybrid energy power supply energy storage system and an energy stora...
