A photovoltaic (PV) grid-interactive system is described in this work for applications that require an uninterrupted power supply. The presented system is such that it allows BLDC motor to run at rated speed at all times irrespective of change in irradiation. A PV-grid hybrid system is a reliable source of supply, whenever the PV system is unable to supply sufficient power to run the motor at rated speed, the grid supplies the deficit power. Additionally, when the motor is not in use, the surplus PV system generated power can be fed to grid. The input voltage of the voltage source inverter (VSI) is regulated by a PI-based outer voltage control and current control is achieved using a proportional resonant (PR) controller. The grid-interfaced PV fed BLDC motor is designed and simulated under various conditions like BLDC motor fed by both PV and grid, BLDC motor not in operation and transition from PV to grid supply. Results from various operating modes demonstrate that the BLDC motor drive fed from a hybrid system operates steadily and dependably enhancing the system performance with reduction in per unit energy cost.

This paper proposed a multi-device L-impedance network based DC-DC boost converter integrated with CLD cell. The proposed structure comprises of three units namely L-impedance, multi-device, and capacitor-inductor-diode (CLD) Cell. The key feature of the proposed structure is that it provides enhanced flexibility to select the voltage gain by selecting number of inductors, number of switches and duty ratio (D). By incorporating CLD cell in the proposed topology the voltage stress across the active switch is reduced. The Limpedance network is responsible for achieving the high voltage gain and the multi-device structure is adopted to reduce the rating of passive components. The derivation of the generalized structure for k-stage L-impedance with m-number of active switches (multi-device) is presented in the paper. Furthermore, the detail analysis for 2-stage L-impedance network with two active switches with its working modes and related equations are presented for 500W. Additionally, to shew the advantages of the proposed topology, it is compared with the existing topologies such as conventional boost converter(CBC), multidevice interleaved boost converter (MDIBC), multidevice switch inductor interleaved boost converter (MDISIBC), quadratic boost converter with CLD (Q-CLD), L-impedance boost converter with CLD (SIBC-CLD) and multi-device boost converter with CLD (MDBC-CLD).

Microgrid monitoring has gained popularity in recent years, owing to their popularity and the power quality disturbances (PQD) caused by renewable energies. Many artificial intelligence-based PQD monitoring strategies have been proposed by researchers. This paper presents a novel method for detecting, classifying and monitoring the power quality disturbances in solar integrated microgrids. Power quality events are detected by analysing the frequency signal with the wavelet synchro-squeezing transform (WSST). The features of power quality disturbances are used to classify them. For PQD classification, the retrieved features are fed into a Convolutional neural network (CNN) classifier, using GoogLeNet and SqueezeNetfier. Thus the accuracy was found to be 99.90% and 93.76% respectively.

N. Samman
My recognition to the Organizing Committee chaired by Professor Nabil Samman for arranging a superb scientific and social program which will offer an unique opportunity for the global community of Oral and Maxillofacial surgeons and all professionals interested in our field to exchange knowledge to share experience and to enhance friendship. The Hong Kong Convention and Exhibition Centre will be the place for a state of the art scientific program where outstanding speakers from all over the world will cover the full scope of our amazing specialty. The 23rd ICOMS will also offer a great opportunity for our young colleagues to learn and to share the results of their scientific work during the different sessions and very specially at the Next Gen Symposium with the theme ‘‘Masterclass from the Rising Stars”.
