Embodiment Construction

[0058] below in figure 1 A first embodiment of the invention is shown in . exist figure 1 A power plant is schematically shown in , which comprises one or more wind power plants WKA. The wind power plant WKA is arranged, for example, on a mountain range above a river valley or the like. Below the wind power plant WKA there is a pumped storage power plant KR, wherein the pumped storage power plant KR is connected via a line LT to an upper storage reservoir OR of the wind power plant WKA. The upper reservoir OR can be designed, for example, as a reservoir in which the individual wind power installations are arranged, so that the upper reservoir OR forms the foundation of the wind power installation WKA. In a further embodiment, the upper storage reservoir OR can be integrated in the mast of the wind power plant WKA or be implemented as a separate storage tank adjacent to the wind power plant WKA.

[0059] Furthermore, the pumped storage power station KR has a generator GE co...

Abstract

The invention relates to an energy store, to a power plant having such an energy store, and to a method for operating the energy store. The energy store has a heat exchanger, which is arranged on a lower basin in a floating manner, which lower basin preferably can be filled with water by means of a first supply line and is designed as a lake, wherein, in separate circuits, water from the lower basin can be fed to a heat pump by means of a second supply line and coolant passing through the heat exchanger can be fed to the heat pump by means of a third supply line such that energy can be removedfrom the water of the lower basin by means of the heat exchanger, causing icing of the water of the lower basin, or in the form of sensible heat, and can be conducted to a load in order to dischargeheat and / or coldness.

Description

technical field [0001] The invention relates to an energy store, a power plant with such an energy store, and a method for operating such an energy store. Background technique [0002] The use of renewable energies has been strongly expanded over the past few years as reserves of fossil energy carriers have become ever more scarce. An increase in the use of renewable energies is also predicted for the next few decades, because in addition to increased raw material prices (which would make the use of fossil energy carriers less economical), energy policy considerations to the adverse effects on the world's climate associated with atmospheric enrichment of carbon dioxide. [0003] Various renewable energy sources are known from the general prior art, for example the use of sunlight, wind power or biomass. However, the two sources mentioned above in particular have a known disadvantage: the use depends on external factors such as the available insolation or the available wind...
