Development of Energy Monitoring System for SmartGrid Consumer Application

The number of electricity consuming equipment for existing household end-user is continuing to increase, and some residential buildings already consume more energy than existing building regulations prescribe. The uprising SmartGrid technology with alternative energy sources could be a key to solve this problem, but it is demanding also for a “smarter” consumer with ability to monitor and manage his loads. Such a monitoring system can also improve energy efficiency, as it can change consumer non-saving habits, by teaching him possibilities where the energy can be saved. Therefore the paper is devoted to development of new concept of household energy consumption monitoring system. Due to new approach of energy monitoring, the costs of needed metering equipment and total metering system are lowered. The proposed method provides energy consumption apportionment between consumers instead of precise energy consumption metering for each consumer type.
