Hybrid power system utilizes wind powered compression for operation of expansion turbine. The hybrid power system includes at least one wind turbine that produces mechanical power, a compressor unit that compresses air, and an expansion turbine that receives the compressed air from the compressor unit and produces power to operate an alternator or a generator that produces electricity. The compressor unit includes one or more compressors coupled to the at least one wind turbine to compress air and may optionally include at least one intercooling device configured to cool the air compressed by the compressors. The hybrid power system may optionally include one or more heating devices configured to heat the compressed air flowing from the compressor unit to the expansion turbine.

In a vertical rotor apparatus that rotates in response to a moving fluid, a shaft defines an axis of rotor rotation. Rotor blades are longitudinally aligned in parallel with the shaft and each rotor blade defines an axis of blade rotation. A sensor generates a signal when any of the rotor blades are within rotor azimuthal angles of blade stall regions. A controller generates blade pitch information for the blade stall regions and an actuator, which is mechanically coupled to each of the rotor blades, alters blade pitch about the axis of blade rotation in accordance with the blade pitch information.

The present invention is an energy storage system comprising a mechanical bellows having an outer flexible material casing with one or more functional elements that operate as actuators for expanding and contracting the outer flexible material casing to store or deliver energy.

Disclosed is a combined energy supply system of wind, photovoltaic, solar thermal power and medium-based heat storage, capable of storing the energy which would have been “abandoned wind” and “abandoned light” temporarily in the form of heat by medium-based energy storage. Heat is released during peaks in the power grid to generate power, which serves the function of adjusting the peaks in the power grid. With the medium-based energy storage, unstable photovoltaic electric energy can be converted into stable heat energy output when a relatively large fluctuation occurs in wind and photovoltaic power generation, and therefore the stable supply of energy sources can be guaranteed efficiently. Furthermore, a second heater can also be used for heating the low-temperature media outputted by a first medium tank (100), or a third heater is used for heating water in a heat exchanger (500), and therefore the energy storage of the medium or the heating efficiency of the heat exchanger is improved.
