Patent Images
1. An energy management system comprising:
- a database configured to store history data about load adjustment;
a demand prediction unit configured to predict a demand at a load to which energy is supplied;
a load adjustment range prediction unit configured to calculate a load adjustment range by using the history data stored in the database, the load adjustment range being defined by lower limit and upper limit of load adjustment limits for the predicted demand, the lower limit being based on the demand and load power decrease, the upper limit being based on the demand and load power increase; and
a display unit configured to display the demand predicted by the demand prediction unit and the load adjustment range calculated by the load adjustment range prediction unit.
