Compressed air energy storage electricity-electricity efficiency calculation method and device based on balance state

The invention relates to a compressed air energy storage electricity-electricity efficiency calculation method based on a balance state. The method comprises the steps that the operation output of a turbine unit is obtained; acquiring air flow of a compression unit; power consumption of a compression unit is obtained; obtaining the air flow of the turbine unit; judging whether the compressed air energy storage system is in a balanced working condition; if the compressed air energy storage system is not in the balanced working condition, the compressed air energy storage system is adjusted to be in the balanced working condition; calculating the total gas consumption of the turbine unit in the operation time; calculating the operation time of the compression unit according to the total gas consumption of the turbine unit and the air flow of the compression unit; calculating system output energy according to the turbine unit operation time and the turbine unit operation output; calculating system input energy a
