Abstract
In the present disclosure, an example method is provided. The example method may comprise operating a pumped thermal system in a charging cycle at a first compression ratio, wherein the pumped thermal system comprises a working fluid circulating through, in sequence, a compressor system, a hot side heat exchanger, a turbine system, and a cold side heat exchanger, wherein the working fluid is in thermal contact with a hot thermal storage ('HTS') medium in the hot side heat exchanger and the working fluid is in thermal contact with a cold thermal storage ('CTS') medium in the cold side heat exchanger. The example method may also comprise operating the pumped thermal system in a discharging cycle at a second compression ratio different than the first compression ratio.
