And a load suppression amount performed by discharging a storage battery, generating a distributed power source, and controlling the load of the load itself to control the load adjustment amount of the distribution substation based on the database at a predetermined time , Calculate the load creation amount that creates the load by charging the storage battery and starting the load that can be shifted in time, and calculate the load adjustment amount required under the distribution substation, the calculated load suppression amount and load creation amount Based on the first distribution calculation device (for example, distribution substation adjustment amount distribution calculation device 9) that distributes to each feeder under the distribution substation, and the load for each feeder based on the database at a predetermined time The load suppression amount for each feeder and the load creation amount for each feeder for controlling the amount of adjustment are calculated, and the load adjustment amount transmitted from the first distribution calculation device is used as the calculated load suppression amount for each feeder. And a second distribution calculation device (for example, feeder adjustment amount distribution calculation device 7) that distributes to each pole transformer under the feeder, based on the load creation amount in units of feeders, and at each predetermined time, based on the database, The load sent from the second distribution calculation device by calculating the load suppression amount for each pole transformer and the load creation amount for each pole transformer to control the load adjustment amount for each pole transformer Based on the calculated load suppression amount for each pole transformer and the load creation amount for each pole transformer, the adjustment amount is allocated to each consumer under the pole transformer and a control command is given. The contribution to the load adjustment amount The third distribution computing device for determining by using the adjustment amount and the overall distribution substation load (e.g., the transformers adjustment amount allocation calculating device 8 columns) and having a.
