Abstract: The invention relates to a method for storing energy by converting the energy into thermal energy and then generating power by means of a gas turbine set with a compressor (1), an expander (6) and a power generator (8), comprising at least one (3) and a second (4) low-temperature storage unit, where the electric energy is stored only in form of high-temperature heat (above the turbine outlet temperature TOT) in a thermal storage unit (5). Depending on the requirements, a compressed gas from the compressor (1) is heated to a temperature approximating the turbine outlet temperature TOT in a low-temperature storage unit (3, 4) and then heated to a temperature level of at least turbine inlet temperature TIT in a high-temperature storage unit (5) using stored heat from electric energy and supplied to a gas turbine (6) in order to generate power.

Abstract translation: 本发明涉及一种通过将能量转换成热能然后通过具有压缩机（1），膨胀器（6）和发电机（8）的燃气轮机组发电来存储能量的方法，至少包括 一个（3）和第二（4）个低温存储单元，其中电能仅以热存储单元（5）中的高温热（高于涡轮出口温度TOT）的形式存储。 根据要求，来自压缩机（1）的压缩气体在低温存储单元（3,4）中被加热到接近涡轮机出口温度TOT的温度，然后被加热至至少涡轮机入口温度 TIT在高温存储单元（5）中使用来自电能的储存热量并供应到燃气轮机（6）以产生电力。

Abstract: The present invention relates to a process of storing energy through the conversion of thermal energy and subsequent power generation by means of a gas turbine set with compressor, expander and power generator, with at least one and with a second low-temperature reservoir, and a high-temperature reservoir with bulk material as the heat storage medium, the electric energy is stored in the form of high-temperature heat above the turbine outlet temperature in a thermal reservoir, that during the power generation phase a compressed gas from the compressor is heated in a low-temperature reservoir to a temperature near the turbine outlet temperature and subsequently heated in a high-temperature reservoir with stored heat from electric power to a temperature level of at least the turbine inlet temperature, and that the ratio between the bed height in flow direction and the mean particle diameter of the bulk material in the high-temperature reservoir is at least 10.
