Multi-energy storage device coordination system and method based on wind-solar-electric-heat-gas conversion module

Abstract

The multi-energy storage device coordination system and method based on the wind-solar-electric hot gas conversion module belongs to the field of energy technology; the system mainly includes a wind-solar-electric hot gas conversion module, a control module, an absorption refrigerator, an absorption heat pump, and a compression refrigerator. Compression heat pump, heat storage device, cold storage device and pipeline solenoid valve group; the method includes calculating the real-time output and input power ratio of the system; obtaining the current reserves of the cold storage and heat storage devices and the predicted power generation of the hydrogen storage device; and based on the real-time input and output relationship Parameter ratio, storage status of heat storage, cold storage, and hydrogen storage devices are adjusted by controlling the relay group and wind-solar-electric hot gas conversion module; pipeline solenoid valves and compression refrigeration are controlled according to the energy storage status of the heat storage device and cold storage device. machine and compression heat pump work; the invention can provide various working modes according to different needs; it can not only ensure the rational utilization of energy, but also maintain high efficiency and flexibility of the system.

Description

technical field [0001] The invention belongs to the technical field of energy, and in particular relates to a multi-energy storage device coordination system and method based on a wind / electricity-heat-gas conversion module. Background technique [0002] Energy has always played an important role in the social and economic development of human beings. At present, non-renewable fossil energy such as oil, coal and natural gas is still the main energy source for the survival of human society. As the global economy and population continue to grow rapidly, the world's demand for energy is also increasing. However, due to the non-renewable nature of these fossil energies, with the over-exploitation of human beings, the non-renewable fossil energies are about to be exhausted. This makes the energy crisis increasingly prominent. At the same time, the massive use of fossil fuels has also had a serious negative impact on the earth's environment. For example, substances produced af...

Problems solved by technology

Wind power, solar energy, etc. are affected by natural conditions, and their output power is intermittent and random. The large-scale grid connection of this type of renewable energy has brought huge challenges to the stable operation of the power grid.

In many cases, it is difficult to match the demand on the load side with the energy supply of distributed clean and renewable energy, resulting in large-scale abandoned wind, abandoned electricity and other energy waste phenomena
