Intelligent control system between reproducible energy sources and electric supply

Abstract

Intelligent control system is a distributed control system composed of one main controller and multiple branch controllers. Through comm. interface, the main controller is connected to each branch controller. In the system, reproducible energy is connected to storage battery. Through auxiliary charge power supply, storage battery is charged. Monitoring and sampling parameters such as each load, reproducible energy, current, voltage of storage battery, as well as through analyzing and processing, main controller outputs control signal to control charging and discharging storage battery. Through comm. interface, main controller controls branch controller so as to select electric supply or battery to supply power for loads automatically. Being connected to electric supply, the system reduces designed capacity of storage battery, uses reproducible energy farthest so as to raise service life of battery. The system is applicable to consumers and illumination system in DC low voltage.

Description

technical field [0001] The present invention relates to electrical energy storage systems and, more particularly, to control systems for charging batteries or powering loads from batteries. Background technique [0002] Renewable energy power generation includes wind power, photovoltaic power, small hydropower, biomass power, biogas power and geothermal power. At present, the most widely used renewable energy with the best prospects is solar photovoltaic power generation, which uses semiconductor devices such as solar cells to directly convert solar radiation energy into electrical energy. The power generation process does not emit or emit any harmful substances and is pollution-free; the power generation system has no movement It has the characteristics of modularization, and has a series of advantages such as dispersible and local installation, flexible operation, reliable operation, easy maintenance, and short construction period. It is an ideal renewable and clean energy...

AI Technical Summary

Problems solved by technology

The main problem in the photovoltaic power generation system: If the system wants to guarantee the power supply for several days, it must charge the power consumption of several days into the battery for backup in one day, which requires the capacity of renewable energy and the battery to be large enough, resulting in energy consumption. And the waste of batteries will also greatly increase the cost of the system and affect its economy

These technical solutions all have the function of energy switching, but renewable energy often requires commercial power as a supplementary or adjusted energy source. So far, there has been no intelligent control system for switching renewable energy such as solar energy and commercial power.
