Conclusions We presented a decentralized algorithm to derive optimal day-ahead schedules using consumer preferences and appliance usage patterns. The proposed algorithm was empirically evaluated across multiple datasets such as DRED and REDD Cost savings of up to 25% and 30% can be achieved in DRED and REDD for monthly electricity consumption.
