Title:
ENERGY STORAGE AND POWER GENERATION APPARATUS FOR NOVEL SOURCE POWER SYSTEM HAVING HIGH PROPORTION OF NEW ENERGY SOURCES
Document Type and Number:
WIPO Patent Application WO/2022/257442
Kind Code:
A1
Abstract:
Provided is an energy storage and power generation apparatus for a novel power system having a high proportion of new energy sources, which overcomes the limitations of existing energy storage technologies and turns uncontrollable energy sources such as wind power and photovoltaic power into controllable energy sources. Provided is a rotating wheel potential energy storage power station which: uses high energy density particles as working medium carriers, generates power by decreasing potential energy, stores energy by consuming power, recycling the working medium and increasing potential energy, has a large moment of inertia, has sufficient reactive storage and operates with constant-rate load characteristics; comprises a rotating wheel device (111), an upper-level repository and a lower-level repository (108, 114) which store the working medium, an energy storage and material flow system which consumes power and conveys and recycles the working medium, a constant-rate working medium flow control device (109), a generator (105), and a substation (117); and is serially matched with a wind or photovoltaic power station (1304) by means of motors (903) to form a wind-photovoltaic rotating wheel potential energy storage power station of an independent power station. Thus, the wind or photovoltaic power station (1304) is turned into a novel power supply side which has no limitation in respect of the proportion of power from any single energy source, adapts power generation capacity to a varying load, is green and safe, and operates efficiently.
