This project aims the study of techniques for monitoring and management of energy consumption with a focus on residential and commercial facilities (consumers) using smartmeters, showing the detailing consumption, identifying the impacts of major equipment on electrical account, consumption and also provide management electricity strategies.The main motivations for the proposed studies come from recent discussions with respect in electrical smartgrids and the growing interest in the use of micro distributed generation systems (micro generation), such as the redefinition of the revenue metering.Especially regarding the measurement system and charging energy, much has been discussed about what would be a new generation of energy "smartmeter". In Brazil and some other countries, considering the context of residential installations, discussions indicate that smartmeters should be capable of: energy measurement in terms of bidirectional flow; communication with central management; horo-seasonal pricing; connection or disconnection due to system prepayment account. These functions represent significant advances with regard to current residential power measurement technology, which is based on passive devices with principle of electromechanical operating and manual data capture, once a month, by visiting employees of utilities, that observes and writes the value displayed on the meter. However, some very important issues in the context of measurement and billing of energy, especially those associated with conservation and power quality has not been discussed in detail, with a view to incorporating new functions to smartmeters.Considering the numerous national and international publications with respect to the influences of non-linear loads or phase unbalance in the electrical system, it was expected that the new powermeters were prepared to deal with such conditions so well determined, in not too future distance, further adjustments necessary to the park meters. Noting that the implementation of such features in meters requires replacement of the entire park meters installed in the country, by electronic meters, generating very high implementation costs for the society.Moreover, it is noteworthy that most of the discussions (and functions) related to so-called electrical smartmeters has explicit concerns from the standpoint of the power utilities or centralized management systems. Thus, consumers continue to be passive users of the meter, though probably they are the funders of replacing existing meters with new ones. The only benefit could be expected from the consumer standpoint would be a choice for an appropriate horo-seasonal rate to their consumption profile.Thus, this project proposes the study of analytical techniques and technologies for the development of energy smartmeters, with a focus on residential microgrids, which besides allowing the basic functions of management of the electric system, typically of power utilities interest, also present the consumer advanced features that enable the management of consumption and generation (if any) of energy in your installation.
