Intelligent control of battery energy storage for microgrid energy management using ANN

In this paper, an intelligent control strategy for a microgrid system consisting of Photovoltaic panels, grid-connected, and li-ion battery energy storage systems proposed. The energy management based on the managing of battery charging and discharging by integration of a smart controller for DC/DC bidirectional converter. The main novelty of this solution are the integration of artificial neural network (ANN) for the estimation of the battery state of charge (SOC) and for the control of bidirectional converter. The simulation results obtained in the MATLAB/Simulink environment explain the performance and the robust of the proposed control technique

PERFORMANCES DES SECTEURS DE L’AGRICULTURE ET DE L’INDUSTRIE MANUFACTURIERE AU MAROC: UNE EVALUATION PAR L’APPROCHE NON PARAMETRIQUE

This article proposes a comparative analysis of productive performance in the Moroccan agricultural and manufacturing industries sector, over the period 1986-2012, using the Malmquist index. The obtained results show that the gain reached in terms of productivity in both sectors is mainly due to the improvement registered in the technical effectiveness rather than being due to the technological progression. Nevertheless, the total factors productivity (TFP) score in the agricultural sector is by far better than the TFP score in the industrial sector. Thus, the former sector exhibits important gains in terms of productivity with respect to the latter one. Furthermore, the contribution of sectorial productivities in the growth of the real Moroccan GDP generally remains very low in the studied period
