“…In the process of creating load curves, some criteria must be taken into consideration; one of this is to select data from a working day (WD) and a non-working day (NWD). In the study presented in paper [13], the authors have performed an analysis of the daily diagram of the supply voltage for a working day and for a non-working day. The choice to perform the analysis separately for working days and for non-working days was made in order to obtain higher accuracy of the results.…”

This paper presents a data mining procedure to generate a typical daily shape of energy consumption based on smart metering measurements. Such a typical daily shape describes an observed or estimated graphical representation of the variation of the electric load against time. This paper proposes two methods for the development of the novel data mining procedure: i) statistical analysis applied to a set of measured data; ii) cluster analysis using the machinelearning algorithm to determine a typical daily shape. The new procedure can be part of the Smart Metering and more precisely of the Automated Meter Reading (AMR). The results of the statistical analysis using the set of measured data show whether or not the average values are representative for the data set. The results of the cluster analysis extend the potential of forecasting a typical daily shape and of offering tools for potential applications to data mining procedure.

“…In fact, the active energy produced by the DFIG contributes to the stability of the rotor angles of conventional generators and whose variation largely impact the electrical system [7], but the reactive energy provided by the DFIG remains critical for these synchronous generators equipping conventional power plants [8,9]. In fact, the results of works in paper [10] shows that fault occurring in electrical grid has the greatest impact on generator swinging. When such a fault occurs, large currents and torques are produced, and action must be taken quickly if system stability is to be maintained.…”

Wind farm has been growing in recent years due to its very competitive electricity production cost. Wind generators have gone from a few kilowatts to megawatts. However, the participation of the wind turbine in the stability of the electricity grid is a critical point to check, knowing that the electricity grid is meshed, any change in active and reactive flux at the network level affects its stability. With a rate of 50% wind turbine penetration into the electricity grid, the stability of the rotor angle is a dynamic phenomenon which is only visible by the variation of the active energy. The purpose of this journal is to verify the impact of wind turbine integration on an electrical grid, by exploiting the relationship between the reactive energy produced by the Doubly Fed Induction Generator equipping most wind energy systems, and the stability of the rotor angle of the synchronous generators equipping the conventional power plants in the electrical system.
