a power generation system

Abstract

The invention discloses a power generation system, which includes a high-pressure gas system, a channel switching system, a gas-liquid mixing system, a hydraulic power generation system and a control system. The high-pressure gas system, the gas-liquid mixing system, and the hydraulic power generation system are connected through the channel switching system. And controlled by the control system; the control system changes the operating state of the power generation system, and the operating state of the power generation system is divided into energy storage state and power generation state: in the energy storage state, the power generation system absorbs new energy from the grid and converts the new energy into compressed The air is stored in the high-pressure gas system; in the power generation state, under the action of the control system, the air energy is converted into electrical energy through the high-pressure gas system, gas-liquid mixing system, hydraulic power generation system and channel switching system. The invention can alleviate the phenomenon of abandoning wind, light, light and water, and improve the problem of low consumption proportion of renewable energy caused by the difficulty of connecting renewable energy to the grid and the difficulty of consumption after grid connection.

Problems solved by technology

With the development of large-scale wind power / photovoltaic resources, my country's wind power / photovoltaic development has maintained a strong momentum of rapid development, but the contradiction between the unconventional development of new energy power generation and the relatively lagging power grid construction has become increasingly obvious, and large-scale is random and problematic. The connection of wind power / photovoltaic energy to the grid with the characteristics of intermittent, anti-regulation and large output fluctuations has a great impact on the voltage stability, transient stability and frequency stability of the system. Wind power / photovoltaic energy is difficult to connect to the grid. Difficulty in consumption and other issues seriously restrict the reform of energy structure

Hydropower units have the characteristics of rapid shutdown, fast adjustment speed, and wide adjustment range. They can perform functions such as peak regulation and frequency modulation in the system. However, conventional hydropower plants and pumped storage power plants have limited roles in large-scale new energy storage and energy conversion. It cannot absorb abundant wind power, solar energy and other large-scale renewable new energy power, and has certain requirements for terrain and geology
