Overcurrent and Distance Protection in DigSilent PowerFactoryAreeb Abdullah
This project involves the theoretical study of Protection Devices, Protection Schemes, Analysis of Control and Logical Blocks of relays being used in the project and practical implementation of both schemes in DigSilent PowerFactory.
This is the third slide set in series of Introductory course on Power Quality for undergraduates. This deals with transient over-voltages, Ferro Resonance, Over Voltage Protection, Switching Transients, Shielding
here dc-dc boost converter designed in MATLAB Simulink and MPPT controller designed in 2 methods(P&O and incremental conductance).
finally, I connect it to Ac grid via the Dc-Ac converter.
this entire system called grid-connected PV system.
Evaluation of aodv routing protocol performance in wireless mobile ad hoc net...Moaath alshaikh
Wireless Manet networks are relatively new compared to existing communications networks, their birth and evolution because of the rapid development of communications devices. Network nodes are connected without any type of connection or preconfiguration. This type of network is used in multiple areas and positions such as a network between vehicles within the city or a network between students in a room or meeting room. It is used in search and rescue operations and natural disasters because the infrastructure is destroyed. It is difficult to create a network of infrastructure in such cases. Each node in this type of network has a radio field in which to create a path to send and receive packets with other nodes that fall within the same domain. This path is formed by the routing protocol, which is the cornerstone of these networks, "Assessment of the performance of the AODV routing protocol in mobile wireless networks (MANET)", performance values of routing protocol in mobile wireless networks. We selected the most popular AODV routing protocol, simulated using the NS-2 emulator under many simulation scenarios, and guidelines for simulated scenarios, which provide good performance in environments with average number of nodes and data flows with them. We hope to be a valuable reference for colleagues who want to study this type of network.

Wind energy analysis for some locations in libyaMohamed Abuella
Modeling, Planning, and Analysis for Wind Energy in Libya.
17 Locations have been chosen for Modeling, Planning, and Analysis of Wind Energy for Different Locations in Libya, ...they are: Tripoli, Misurata, Tarhunah, Ghanima, Msallata, Zuwara, Gharyan, Sirte, Benghazi, Magrun, Derna, Houn, Gadamis, Sabha, Kufra, Tobruk, Jaghbub
Also, a comparison with Berlin in Germany has been conducted alongside the Libyan locations.
Qualifying combined solar power forecasts in ramp events' perspectiveMohamed Abuella
Applying a qualifying metric for solar power forecasts to assess their capability to predict the ramp events, especially by the combined forecasts, then those forecasts can be implemented for: Managing high ramp-rates of PV solar power generation; Optimal energy management of energy storage systems; Voltage regulator settings on feeders with PV distributed generation.
Using statistical and machine learning techniques to forecast the PV solar power, which can be implemented for: • Managing the economic dispatch, unit commitment, and trading of PV solar power generations with other conventional generations; • Using with situational awareness tools to manage the ramp limitation; Optimal energy management of energy storage systems; • Voltage regulator settings on feeders with PV distributed generation.
