Estratégias de planejamento para otimização do consumo residencial de energia elétrica: uma abordagem baseada em smart home e sistemas fuzzy

Residential energy consumption has grown steadily over the last decades, becoming a problem for companies in the electricity sector, for consumers and for the environment. The traditional measurement systems are not sufficient and have limitations in providing adequate real-time information about consumption. As also, they are not prepared to deal with variable energy costs in the context of a market with dynamic prices that depend on the energy mix. The future of electric grid, called Smart Grid, will not only be designed with measurements based on the residences, but also on the individualized equipment consumption level. From the residential side, consumers generally suffer from a lack of information on the specific equipment energy consumption impact and, consequently, on the required behavior to reduce its consumption. In this context, this work aims on a smartphone monitoring system concept, to control energy using fuzzy logic, in order to provide to the user ways to maintain his energy consumption, through consumption profiles, within the user-defined consumption patterns. The energy reduction demand through the consumption profiles working with habitant dependence degree on the electrical equipment present in the residence, promote a smaller impact on inhabitant well-being and the daily life.

Implementação de um sistema supervisório em unidades geradoras de energia elétrica de sistemas isolados instalados em municípios do estado do Amazonas
(Universidade Federal do Pará, 2021-08-30) SILVA, Jefferson Emilio Maciel da; LEITE, Jandecy Cabral; http://lattes.cnpq.br/7279183940171317
This master's dissertation consists of an exploratory research carried out by monitoring the maintenance activities carried out in the Thermoelectric Power Plants installed in the cities of the State of Amazonas, with the objective of implementing a monitoring system for electrical quantities coming from engines, also called Engenies Electric Power. This is a field research with qualitative approaches, taking into account the implementation of an automated system to capture the variations in electrical quantities (Voltage, Current, Power and Power Factor) of these energy generating units. The capture of these data, which are the variations of electrical quantities, occurs with the use of PLC, transducers, Modem, among other equipment, which are stored in a database (computer) that using a Supervisory System modeled for this purpose, providing the visualization of these data, in real time, in a friendly and interactive interface. From the monitoring of these data, via a Supervisory System, and with the use of data manipulation tools from the SCADA system, an interface for the generation of graphics was modeled, which significantly contributed to the interpretation of these data. And in addition, make it available remotely, to everyone involved in the activities of the plants, thus being able to access the Supervisory System from anywhere in the world, through the internet.

Smartcom: uma arquitetura inteligente de gerenciamento de consumo de energia para smart home
(Universidade Federal do Pará, 2017-08-25) OLIVEIRA, Edvar da Luz; FRANCÊS, Carlos Renato Lisboa; http://lattes.cnpq.br/7458287841862567
With advances in information technology for a variety of areas, such as health and wellness, Smart Home based solutions using Internet of Things (IoT) technologies are gaining in popularity, including energy-saving alternatives based on Home Energy Management Systems (HEMS). This thesis defines an innovative architecture, called SmartCoM, which is implemented to monitor and manage residences using IoT technologies. Such a strategy involves defining the parameters that can affect the interoperability between measurement, management and the layers of data communication, which are the resources necessary for the hardware devices to perform the intended monitoring and measurement. In addition, an interface is defined by a middleware layer to integrate the management of external installations and the visualization of data through cloud services. The SmartCoM architecture is defined end-to-end in detail from the consumer's point of view and optimization strategies are employed for both the end customer and the utility. In order to evaluate the proposed architecture, a case study was elaborated, from which the viability of developing solutions for Smart Home according to the requirements described in SmartCoM is observed.
