Abstract

The invention discloses a battery charging method and terminal based on an optical storage diesel micro-grid system. The method comprises the following steps: monitoring the battery electric quantity of the optical storage micro-grid system in real time; when the generating capacity of a photovoltaic inverter in the optical storage micro-grid system is lower than the power consumption of the optical storage micro-grid system and the power of a battery is lower than a first threshold value, a diesel generator is controlled to supply power to an electrical load of a user, a rectifier is controlled to be electrically connected with the diesel generator, and the rectifier is started and controlled to output current to supply power to the optical storage micro-grid system. Enabling the battery to be in a non-charging and non-discharging state or a charging state with a current lower than a preset current threshold value; when the electric quantity of the battery is lower than the preset first threshold value, the diesel generator supplies power to the user load, and meanwhile, the rectifier is introduced, so that the diesel generator can supply power to the optical storage micro-grid system, the problem that the optical storage micro-grid system cannot be restarted due to serious power feeding of the energy storage battery in severe weather is solved, and the service life of the optical storage micro-grid system is prolonged. And the stability of the optical storage micro-grid system is ensured.

Description

technical field [0001] The invention relates to the technical field of electric power control, in particular to a battery power supplement method and terminal based on an optical diesel storage micro-grid system. Background technique [0002] In the early days, in areas where the power grid could not be laid, such as remote mountainous areas or islands, electricity consumption was a big problem. Local residents usually purchased diesel generators to generate electricity. The amount of diesel used is high and the economic cost is high, and a large amount of air is generated when diesel is burned. Pollutants destroy our living environment. [0003] Photovoltaic power generation has become the first choice for green energy configuration. However, in areas without power grids, it is impossible to directly integrate the AC power generated by photovoltaics into the power grid. At this time, an energy storage system needs to be configured. Charge and discharge. [0004] The photo...
