  • Patent number: 11593690
    Abstract: Provided is a data prediction system for predicting a future prediction value. The data prediction system has a data management device which manages data and a prediction operation device which models tendency of an error amount of a prediction operation result calculated on the basis of a correlation with a major explanatory variable and corrects a future prediction value. The data management device includes a storage unit which stores prediction target past measurement data observed with a time transition and explanatory factor data explaining the prediction target past measurement data.
    Type: Grant

  • Publication number: 20190279239
    Abstract: The present invention is provided with: a player action prediction unit that predicts the action of a player and calculates a sales order information prediction value; a market physical restraint prediction unit that predicts the state of a power transfer path, which includes grid-connection line available capacity indicating excess transferred power between areas, and calculates a prediction value for the state of the power transport path; and a market prediction unit that predicts a market price on the basis of the sales order information prediction value and the prediction value for the power transfer path state.
