Problems solved by technology
[0003] However, the traditional charging and discharging circuit with energy storage equipment needs to judge and switch the charging and discharging state through various algorithms and logic. When the logic is unreasonable, there will be a problem of repeated switching of the charging and discharging state, resulting in frequent charging of the circuit in a short period of time. Discharge, can not really achieve fast charge and discharge switching

The invention provides a charging and discharging switching method, device and system of a bidirectional converter and a medium. The charging and discharging switching method comprises the steps of obtaining a power actual value and a power given value of energy storage equipment; obtaining a current given value of the energy storage equipment based on the actual power value and the power given value; according to the current given value, the loop charge and discharge state is judged; and determining driving distribution of the bidirectional converter according to the loop charging and discharging state. Compared with the prior art, additional logic judgment and switching of the charging and discharging states of the bidirectional converter are not needed, and the adoption and calculation cost is saved; the charging and discharging states can be recognized according to the variables of the loop, additional charging and discharging state judgment and switching strategies are not needed, control is simplified, and rapid charging and discharging switching is achieved.
Description
technical field [0001] The present invention relates to the technical field of battery management, and in particular, to a charging and discharging switching method, device, system and medium of a bidirectional converter. Background technique [0002] With the construction of a new power system with new energy as the main body, the proportion of wind power, photovoltaic and other new energy power generation in the power grid is getting higher and higher. Due to the randomness and volatility of new energy power generation, it is generally Energy storage equipment will be configured to provide additional power through the energy storage equipment to achieve frequency regulation of new energy, thereby ensuring the system response speed. [0003] However, the traditional charging and discharging circuit with energy storage device needs to judge and switch the charging and discharging state through various algorithms and logic. When the logic is unreasonable, the problem of repea...
