A Novel Energy Management of Smart Home with Multi Knapsack Load Monitoring Analysis

The paper presents Home Energy Management System (HEMS) obtained from smart grid for residential consumers. The system integrates conventional source of supply from grid with renewable energy resources of solar system .The paper provides with the method of obtaining meter reading, total load consumed  as well as individual load consumed and about load demand in a particular time of interval. The paper describes the IEEE 802.15.4 standard protocol wireless sensor network technology. Zigbee technology uses these standards which is an application software module using small, low power and data rate communication technique enabling to monitor and control the home appliances. Further the paper describes the use of web services and smart phone to monitor and control the load appliances. Lab view software is used for simulating home energy management centre and study the results. The microcontroller interface linked with Zigbee transceiver which uses standard RS 232 protocol/ interface bus for pc communication. In addition wireless protocol is used for communication with Android gadgets.
