The scheduling algorithm concerns the shiftability and interruptability of loads. A single-objective optimization technique is employed by using a cost metric that combines CO 2 emission and the electricity cost. The algorithm runs continuously in time. A Knapsack approach is used to define the set of appliances to run in the next time interval. Household scenarios: Scheduler Output Demand peak flattening can be observed from the aggregation and shifting of appliance loads in 100 residential households.
