Dark-fermentation biomass energy power introduced power supply system of renewable energy power grid

Abstract

The invention relates to a dark-fermentation biomass energy power introduced power supply system of the renewable energy power grid. The input end of a first electric energy storage device is connected with the output end of a renewable energy power generator, and the output end of the first electric energy storage device is connected with the input end of an AC converter; the electric energy output end of a dark-fermentation biomass energy power generator is connected with the input end of the first electric energy storage device; a controller comprises a processing unit and a control unit, and the processing unit is electrically connected with the first electric energy storage device and the control unit, and the control unit is arranged at the electric energy output end of the dark-fermentation biomass energy power generator. When the generating capacities of multiple renewable energy power generators, influenced by weather factors as wind power and illumination, in the renewable energy power supply system are insufficient, the controller can introduce electric energy converted by the dark-fermentation biomass energy power generator into the power grid of the renewable energy power supply system, so that the load rate of the power grid and the dumping rate of electric power are reduced, stable power supply of the power grid is achieved, and the utilization rate of renewable energy is improved.

Description

technical field [0001] The invention relates to the technical field of green electric power, in particular to a renewable energy grid that introduces dark fermentation biomass energy power to reduce the load rate of the grid and achieve stable power supply effects for the grid. Grid power supply system. Background technique [0002] In the era of high energy prices and increased energy demand, it is expected that global energy demand will continue to grow. The energy policies of various countries have begun to seek self-renewable energy sources, such as hydropower, wind energy, solar energy, and biomass power. Among them, solar energy and wind energy are the most convenient green energy sources, and they are not subject to regional restrictions. Therefore, they have attracted more attention, and their development is relatively rapid and mature. [0003] At present, there are three types of wind-solar hybrid renewable energy power supply systems using solar and wind power: 1...
