Energy storage conversion system and method based on energy storage bidirectional converter

The invention relates to an energy storage conversion system and method based on an energy storage bidirectional converter, and relates to the field of AC power grid control and regulation, and the system comprises the energy storage bidirectional converter which is used for converting the energy storage bidirectional converter into the AC power grid when the received predicted load consumption power in the next time segment is greater than the maximum load power of the AC power grid. Starting the battery energy storage system to carry out self-adaptive charging processing on the alternating current power grid based on the difference power of the predicted load consumption power exceeding the maximum load power in the next time segment; and the information prediction device is used for predicting the predicted load consumption power in the next time segment based on each total power amount corresponding to each previous time segment. According to the invention, the energy storage bidirectional converter can b
