Peak shaving and load shifting power supply system and method based on methanol water reforming hydrogen generation power generation system

Abstract

The invention discloses a peak shaving and load shifting power supply system based on a methanol water reforming hydrogen generation power generation system. The system comprises a control device, a methanol water storage and transmission device, at least two methanol water reforming hydrogen generation power generation modules, a power conversion device, a load and an electronic switch, wherein the control device is electrically connected with the methanol water storage and transmission device, the methanol water reforming hydrogen generation power generation modules, the power conversion device and the electronic switch and controls the working conditions of the methanol water storage and transmission device, the methanol water reforming hydrogen generation power generation modules, the power conversion device and the electronic switch, and the electronic switch is used for connecting or disconnecting a mains supply; when the mains supply is in a power utilization peak, the control device controls the electronic switch to cut off the mains supply and controls an appropriate amount of methanol water to be reformed to generate hydrogen and the power generation modules to run according to the electricity utilization power of the load so as to supply power to the load; and when the mains supply is in a power utilization valley, the control device controls the methanol water to generate hydrogen and the power generation modules to rotate and also controls the electronic switch to connect the mains supply so as to supply power to the load. The system has the advantages of high power supply continuity, peak shaving and load shifting, energy saving, emission reduction and high power supply safety, and is easy to control.

Description

technical field [0001] The invention relates to the technical field of power supply systems, in particular to a peak-shaving and valley-filling power supply system and method based on a methanol-water reforming hydrogen production power generation system. Background technique [0002] At present, the domestic electricity demand is increasing, but the domestic electricity demand management is still at a relatively low level. The power generation capacity of a power plant is usually fixed and cannot be easily changed, but the peak of electricity consumption is usually during the day, resulting in insufficient electricity during the day, and a low point at night, and the excess electricity that cannot be generated is wasted. In order to realize the scientific, orderly, and economical use of electricity, improve the efficiency of electricity consumption, and achieve the goal of energy conservation and environmental protection, the national power department has introduced a ladde...

Problems solved by technology

[0009] When the electrolytic water hydrogen production device or hydrogen fuel cell fails, it can only continue to use the mains power supply; when a single electrolytic water hydrogen production device or hydrogen fuel cell is not enough, it is difficult to increase its hydrogen production and power generation, and the production When the amount of hydrogen and power generation is too large, it is difficult to reduce the amount of hydrogen production and power generation
