Harmony search optimization technique for home management system in smart grid: HSA technique for HEMS

In this paper, we study challenges of electricity consumption management in smart grid, and focus on the different impact of operational time intervals of appliances to ascertain if consumer's comfort can be maximized. The appliance execution process is built on continuous cycle parts, having a demand power rating with objective of obtaining a minimal electricity bill satisfying period, energy need and consumer choice limits. Harmony search optimization technique is propose to schedule home appliances. Results from simulation show that optimization technique is able to yield our set of objectives: electricity bill minimization, energy consumption minimization, peak to average ratio reduction and consumer comfort maximization. Additionally, feasible region (FR) is calculated for appliances which show relationship in terms of cost and energy load.
