The invention discloses an energy storage apparatus charge and discharge performance evaluation method of an optical-storage combined power generation system. The method comprises the following steps of measuring rated power energy storage apparatus charge / discharge time; measuring rated power energy storage apparatus charge / discharge response time; measuring rated power energy storage apparatus charge / discharge conversion time; and based on the above time parameters, evaluating energy storage apparatus charge / discharge performance of the optical-storage combined power generation system. In the invention, charge / discharge time performance of the energy storage apparatus, charge / discharge response time performance and charge / discharge conversion time performance are comprehensively considered so that the energy storage apparatus charge / discharge time performance of the distributed optical-storage combined power generation system is comprehensively reflected.
Description
technical field [0001] The invention relates to a charging and discharging performance evaluation method of an energy storage device of an optical storage combined power generation system, and belongs to the technical field of charging and discharging performance evaluation of the optical storage combined power generation system. Background technique [0002] In recent years, countries around the world have increased the development and application of new energy sources represented by solar energy and wind energy. Considering the impact of intermittent and random new energy power generation system grid connection on the stable operation of the power grid, new energy power generation systems with energy storage devices have begun to receive attention, and their research and production scale has gradually expanded. [0003] However, the corresponding detection methods and evaluation standards are relatively lagging behind, which has become a constraint for the industrial produ...
