Utility-friendly Hybrid Energy Conversion System for Apportioning Concentrated Solar Radiation in Real Time Upon Selective Demand Between a Plurality of Solar Energy Conversion Devices, Including a Photovoltaic Receiver

摘要

Extremely fast dynamic control is allowed for hybrid PV/T (photovoltaic/thermal) distributed power production using concentrated solar power by manipulating the transmissive or reflective state of a capture element or mirror or lens that can pass highly concentrated solar light from one energy conversion device to another, such as a thermal collector and a photovoltaic receiver, such as a vertical multijunction cell array. This allows superior quality electrical backfeed into an electric utility, enhanced plant electrical production revenue, and responsiveness to a multitude of conditions to meet new stringent engineering requirements for distributed power plants. The mirror or lens can be physically articulated using fast changing of a spatial variable, or can be a fixed smart material that changes state. A mechanical jitter or variable state jitter can be applied to the capture element, including at utility electric grid line frequency.

1. A hybrid energy conversion system for apportioning concentrated solar radiation (9) in real time upon selective intelligent demand between a plurality of solar energy conversion devices, including a photovoltaic receiver, said system comprising:
a collector trough (10) so sized, positioned, oriented and shaped to concentrate said solar radiation to create a concentrated angular distribution of light (11), said concentrated angular distribution of light possessing at least one of a focal length (L) and a delivery length, as measured from a surface of said collector trough to a relative maximum (FOCUS) of highly concentrated solar light (111) formed thereby; a first solar energy conversion device selected from a thermal collector (T), and said photovoltaic receiver (PV), so formed, sized, shaped, positioned and oriented to receive at least some of said solar radiation from said collector trough via said highly concentrated solar light in said concentrated angular distribution of light; a selectively deployable capture element (Y) so formed, sized, shaped, positioned and oriented to capture selectively on demand at least some of said concentrated angular distribution of light for any of reflection to, partial reflection to, direction to, and conversion by, a second solar energy conversion device selected correspondingly from the other of said photovoltaic receiver and said thermal collector; said capture element so articulatably formed as to be selectively deployable for light capture by at least one of transitioning at least one optical property selected from reflectivity and transmissivity; and gross modulation across a spatial variable comprising at least one of a capture angular range (V) and a capture translational range (Z).
