Optimal Appliances Scheduling of Home Energy Management System Using Dynamic Programming Method for Auto Demand Response

摘要

An optimal load shedding method of home energy management system (HEMS) for auto-demand response in residential load is presented. HEMS computes a day-ahead shedding schedule of each smart plug by using dynamic programming for optimal demand reduction. Each smart plug turn-off/on load during demand response event according to the shedding schedule. A case study of 2 hours demand response is performed by using 9 interruptible loads. As result, load shedding is up to 152 WH and the total demand is lower than limitation. HEMS assists human to choose the shedding load and execute turn off and on automatically.
