Abstract: A method and controller of dynamically determining a current system curve in a heat power system, in which the heat power system comprises a regulator and sensors. The controller controls an output of the regulator to find the current system curve, collects and checks sensor values with limited accuracy to determine if properties of the sensor values indicate that a point of the current system curve has been reached. When at least two points are found the controller models the current system curve by linear interpolation between the first and second point of the current system curve.

Abstract: The present application provides a steam discharge pipe blowback protection system for use with a steam discharge pipe and a flow of steam therethrough. The steam discharge pipe blowback protection system may include a vent stack pipe and a drip pan with an exit end of the steam discharge pipe extending through the drip pan and into the vent stack pipe. The drip pan includes a slide plate positioned around the steam discharge pipe such that a blowback in the flow of steam causes the slide plate to seal the drip pan.

Abstract: An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.
