In the day today life, the power demand increases with increase in development of technology and modern tools, the utilization of the power progressively raises more than the power generation which results in power demand. To reduce the power demand, it is necessary to focus on the power generation while cost function minimization also plays a vital role. The home power management system is proposed with the objective to reduce the electricity cost and also to avoid the problem of high peak demand. Recently many methods have been discussed in the area of Home energy management, but monitoring and controlling the operation of power units from customer point of view has its own benefits depending on the comfort level of customer. The proposed method consists of a photovoltaic system with battery, PLC and SCADA. This controller schedules the power units in response to the demand of the customer. The available power units comprising of solar power, battery power, grid supply and the utilization of home appliance are categorized and monitored regularly in terms of current sensor. The primary power units, preferably solar are chosen automatically as per the instructions given to the controller. When the primary power unit (solar) is not able to supply power, due to its intermittent nature of generation, the controller shifts to next power units accordingly. The simulation results show that the proposed system based on Home Energy Management (HEM) reduces the electricity cost, peak demand problem and enhances the efficiency of energy use and efficiency. The smart controller is operated based on SHEM and selects the power units accordingly. The case study justifies the effectiveness of the proposed system for energy management system in smart home. The proposed system is developed and simulated in MATLAB/SimPowerSystem (SPS).
