Abstract

The invention discloses a civil direct current system which comprises an energy collecting sub-system and/or energy accumulation sub-system, a dispatching control sub-system, an energy using sub-system and direct current power utilization network. The dispatching control sub-system controls the direct current output of the energy collecting sub-system and/or energy accumulation sub-system, so that the direct current power utilization equipment contained by the energy using sub-system is powered through the direct current power utilization network. Due to the fact that the energy collecting sub-system and/or energy accumulation sub-system mainly collects the direct currents of renewable energy sources such as solar energy, wind energy and fuel cells and the alternating currents of trough mains supply and different energy has different power supply quantity at different dates and time, the direct current output of the energy collecting sub-system and/or energy accumulation sub-system can be controlled through the dispatching control sub-system so as to supply stable direct currents to the direct current power utilization equipment. By the civil direct current system, the renewable energy sources such as the solar energy, the wind energy and the fuel cells and the trough mains supply can be effectively utilized.

Description

Technical field [0001] The present invention relates to the technical field of direct current power consumption, in particular to a civil direct current system and a direct current power supply method that effectively utilizes renewable energy such as solar energy, wind energy, fuel cell, etc. and valley city power. Background technique [0002] Energy and environmental issues have become major problems faced by the world and mankind. The development of new energy sources and the enhancement of the use and efficiency of renewable energy sources have increasingly become the focus of attention of all countries.
