Wind energy harvesting can be performed using an airfoil structure. Such harvesting can include control of airfoil operation, such as to support harvesting energy from oscillations associated with one-degree-of-freedom (1-DOF, e.g., pitching) or two-degree-of-freedom (2-DOF, e.g., pitching and plunging) operation. For example, control of airfoil operation can include sustaining stable oscillation corresponding to limit-cycle oscillation (LCO) in pitch, or both pitch and plunging degrees of freedom. Examples can include use of a synthetic jet actuator (SJA) to modify a flow attachment characteristic associated with the airfoil structure. According to various examples, a modified Glauert airfoil configuration can be used. The approach herein can also be used to achieve aerodynamic control of aircraft, such as unmanned aircraft.

The invention relates to controlling a wind turbine. A predefined power coefficient data structure and a predefined thrust coefficient data structure respectively comprise values of a power coefficient and a thrust coefficient as functions of blade pitch angle and tip speed ratio. The invention includes using an iterative search algorithm to determine values of pitch angle and tip speed ratio that maximise the power coefficient value in the predefined power coefficient data structure subject to a constraint that the thrust coefficient value in the predefined thrust coefficient data structure is no greater than a maximum threshold thrust coefficient value. A rotor speed reference is determined based on the determined tip speed ratio value and on a received wind speed. The determined pitch angle value is set as a pitch angle reference. The wind turbine is controlled in accordance with the pitch angle and tip speed ration references.

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.

The present application discloses a blade and an axial-flow impeller using the same. The present application provides a blade, comprising a blade tip, a blade root, a leading edge and a trailing edge, wherein the leading edge and the trailing edge extend from the blade tip to the blade root, respectively. The blade is capable of rotating about a rotation axis X which is perpendicular to a normal plane. In a projection of the blade on the normal plane, a circumferential included angle between the leading edge and the trailing edge forms a wrap angle, and the wrap angle decreases gradually from the blade root to a middle blade height of the blade and increases gradually from the middle blade height to the blade tip. Wherein, the middle blade height is an arc line formed by center points of the blade tip and the blade root along a radial direction. The blade of the present application allows for significantly reduced turbulent vortices and reduced intensity in the vicinity of the junction of the leading edge and the blade tip of the blade and in the vicinity of the junction of the trailing edge and the blade tip of the blade during the operation of the axial-flow impeller, leading to evenly lightened load of airflow on the blade, more uniform distributions of velocity and pressure, reduced velocity and pressure pulsations, and reduced noise.

A wind turbine may be fitted with the facility store electricity indirectly using one or more thermal stores. The power-conversion machinery is installed within the wind turbine nacelle which rotates to point the turbine into the wind. The thermal storage is realised in the fixed frame - i.e. it does not rotate with the nacelle. The connection between the fixed frame and the rotatable frame is via one or more rotary heat exchangers. While the energy storage is charging, heat passes through the hot heat exchanger to a hot store or coldness passes through the cold heat exchanger to a cold store or both. During discharging, the opposite flows occur. Each rotary heat exchanger has a shell-and-tube configuration. The tube bundle rotates with the nacelle. The shell comprises one set of surfaces that does not rotate and one that does rotate.
