The main resources used in electricity generation are becoming fewer, while the impact of renewable resources is still quite small. To allow the necessary time for the technology of renewable resources to mature, a requirement is to increase the energy efficiency. In this regard the smart grid concept was implemented, but whose efficiency depends on creation of a framework through which the end user can actively participate in the energy marketplace. End users must be able to understand how the energy is used so that they could find possibilities to increase the efficiency of energy. Within this paper the architecture of a smart system (smart meter) capable to disaggregate the whole energy consumption into individual consumers is presented. This way, the user will have a better understanding on how the energy is used, will find major consumers and will be able to reduce his consumption.
The realization of measurement and control modules for distributed data transmission is proposed, to be implemented on automatic irrigation systems, so that it may lead to an intelligent system of irrigation combined with automatic nutrients' injection, relying on the sensory investigation of the environment and soil parameters' conditions. The decisional algorithm of the control center prescribes combined irrigation schedules according to the exploited crop and to its development specificity, and the investigation is carried out at the irrigation cell level, modularly. The communication data flow exploits the existent infrastructure of power supply of the automatic irrigation systems as a physical support, and it is developed through the Power Line Communications (PLC) technique. The system architecture is so conceived that it should allow its implementation on the automatic irrigation systems of both circular movement (central pivot) and linear movement. When a monitoring, control and data storage application involves the presence of the sensors and actuators on a large area, the FieldPointdistributed input-output systems offer an integrated, modular and economical solution for industrial use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
