Abstract
A power plant for generating electricity has a high temperature heat reservoir and a low temperature heat reservoir. The plant is operated to store heat during off peak power periods and to use the stored heat during peak power periods to produce additional electricity.
Claims18
A power plant for generating electricity comprising an energy source, turbines to convert energy from said energy source to electricity, a high temperature heat reservoir and a low temperature heat reservoir, said high temperature heat reservoir being solid and being connected to receive at least some of said electricity generated by said power plant, said low temperature heat reservoir being connected to receive steam from said turbines, said reservoirs being connected to return heat energy to said turbines, with a controller for said power plant to operate said power plant to store energy in said reservoirs during off peak power periods and to transfer heat from said low temperature heat reservoir to said high temperature heat reservoir and from said high temperature heat reservoir to said turbines during high peak power periods, said turbines being connected to produce electricity from said heat energy.
A method of operating a power plant for producing electricity, said power plant having an energy source and means to convert energy from said energy source to electricity, a high temperature heat reservoir and a low temperature heat reservoir, said method comprising operating said power plant substantially at maximum output capacity on a continuous basis during high peak power periods and off peak power periods, using at least part of said electricity generated by said power plant during off peak power periods to transfer heat to said high temperature heat reservoir, transferring steam from said means to convert energy to said low temperature heat reservoir, controlling said plant to discharge said reservoirs by transferring heat from said low temperature heat reservoir to said high temperature heat reservoir and from said high temperature heat reservoir to said means to convert energy during peak power periods, thereby increasing said output capacity of said plant.
A method of operating a power plant for generating electricity, said power plant having a high temperature heat reservoir, a low temperature reservoir, an energy source and means to convert energy from said energy source to electricity, said means including a boiler, said method comprising operating said boiler at substantially maximum capacity on a continuous basis during high peak power periods and off peak power periods, using at least part of said electricity generated by said power plant during off peak power periods to transfer heat to said high temperature heat reservoir, transferring steam from said means to convert energy to said low temperature heat reservoir, controlling said plant to discharge said reservoirs by transferring heat from said low temperature heat reservoir to said high temperature reservoir and from said high temperature heat reservoirs to said means to convert energy to electricity, thereby supplementing said substantially maximum output of said boiler.
