Abstract
Provided is a control device of a home energy management system (HEMS). The control device includes a communication unit connected to an HEMS gateway, a storage unit configured to store information on power consumption of each of home appliances connected to the HEMS gateway, and a control unit configured to predict a power generation amount of a photovoltaic (PV) module connected to the HEMS gateway and generate information on usable time of each of the home appliances on the basis of the predicted result and the information on the power consumption.
Claims11
A control device of a home energy management system (HEMS) having a plurality of home appliances, the control device comprising:
- a communication interface connected to an HEMS gateway;
- a storage configured to store first information on power consumption of each of the home appliances connected to the HEMS gateway and second information in which each of the home appliances is used for each time zone;
- and
- a controller configured to:
- predict a power generation amount as a time-based power generation amount of a photovoltaic (PV) module connected to the HEMS gateway for time zones within a predetermined period,
- set, based on the second information, priorities of the home appliances differently according to the time zone,
- classify, for each time zone, at least one of the home appliances as an operable device on the basis of the predicted power generation amount, the first information, and the set priority,
- generate, based on the classifying result, an operation schedule of each of the home appliances for the time zones, and
- control an operation of each of the home appliances on the basis of the generated operation schedule.
