Abstract

This project proposes the development of a new system for monitoring and management of residential electrical loads. The work aims to seek a trade off between accuracy and intrusiveness. The basic idea is to combine the best features of two types of monitoring, Intrusive and Non-Intrusive, and provide information to the consumer through a computer, smartphone or tablet through which the user can set preferences for the operation of appliances. Intrusive Monitoring Systems measure each device individually and only organizes the measured values, thus it is an accurate and more expensive technology, but computationally simpler. The Non-Intrusive Monitoring Systems aim to estimate consumption of each load by recognizing their operating characteristics through measurements performed at the primary extension wiring. As the Non-Intrusive Monitoring makes use of only one sensor it is a cheaper system, less accurate but computationally more complex. The union of these two approaches is expected to reduce cost without deterioration of precision. Coupled with the monitoring system it will be developed an artificial intelligence able to decide which appliance should be turned on / off in order to minimize the value of the energy bill considering the time of use tariff and other settings desired by the consumer. The proposed methodology will provide the capability and effectiveness for the residential consumer in reducing electricity costs. (AU)
