“…This paper presents some research conducted within the SMARTRADE (Intelligent System for Trading on the Wholesale Electricity Market) research project, which has as objective the design and development of an informatics system prototype for forecasting, analysis and decision models for electricity suppliers in order to estimate consumption and production in an appropriate way for efficient transactions in the wholesale energy market. A series of our own studies, like [1] or [2], as well as some established ones, such as [3], [4] or [5], offer detailed definitions of the smart grid concept. Thus, if the term grid refers to the electrical network, the term smart refers to digital technologies which ensure the interaction of customers with the electrical devices.…”
