Embodiment Construction

[0017] The present invention discloses a combined system for grid connection and / or stand-alone application, which combines the advantages of two of the most economically feasible renewable energy sources (wind and water) and solves the intermittent problems that limit the application of wind power generation sexual issues. Furthermore, embodiments of the present invention also provide a solution for directly combining wind power with pumped storage hydropower, as well as with conventional hydropower (ie, the flow of rivers). As will be explained, a combined wind-pumped hydroelectric system can be operated as a grid-connected system and / or as a stand-alone system. In some embodiments, active components may be grouped together via a common alternating current (AC) bus or direct current (DC) bus, where, in the latter case, via any available power converter DC bus . Furthermore, inventive embodiments disclosed herein provide novel voltage and frequency regulation through local ...

Abstract

An integrated, wind-pumped hydro power generation system includes at least one wind turbine generator device configured to generate output power for a common bus, and at least one hydro generator device configured to generate output power for the common bus. The hydro generator device is powered by water flow. The wind turbine generator device and the hydro generator device include corresponding local controls associated therewith, and a set of supervisory controls is in communication with the common bus and each of the local controls.

Description

technical field [0001] The present invention relates generally to a renewable power generation system, and more particularly, to a system and method for combining wind power and pumped storage hydro power systems. Background technique [0002] Wind is one of the fastest-generating renewable energy sources. A turbine that uses the kinetic energy of the wind to generate mechanical energy, converting the mechanical energy into electricity. Wind turbines typically have two or three blades that face or face away from the wind. As the wind causes the blades to rotate, the shaft of the turbine rotates. The mechanical energy generated can be used to power a task, such as pumping water, or it can be converted into electricity. When connected to a generator, the rotation of the shaft drives the generator, which in turn generates electricity. [0003] However, the intermittent nature and variable speed of the wind are major disadvantages of wind power systems, which lead to low sys...
