Internet of Things (IoT) enabled Smart grid (SG) is one of the most advanced technologies, which plays a key role in maintaining a balance between demand and supply by implementing demand response (DR) program. In SG, the main focus of the researchers is on home energy management (HEM) system, which is called demand side management (DSM). Appliance scheduling is an integral part of HEM system as it manages energy demand according to supply, by automatically controlling the appliances and shifting the load from peak to off peak hours. In this paper, the comparative performance of HEM controller embedded with heuristic algorithms; harmony search algorithm (HSA), enhanced differential evolution (EDE) and harmony search differential evolution (HSDE) is evaluated. The integration of renewable energy source (RES) in SG makes the performance of HEM system more efficient. The electricity consumption in peak hours usually creates peaks and increases the cost but integration of RES makes the electricity consumer able to use the appliances in the peak hours.We formulate our problem using multiple knapsack theory that the maximum capacity of the consumer of electricity must be in the range which is bearable for consumer with respect to electricity bill. Feasible regions are defined to validate the formulated problem. Finally, simulation of the proposed techniques is conducted in MATLAB to validate the performance of proposed scheduling algorithms in terms of cost, peak to average ratio and waiting time minimization.
