Abstract
In this thesis present the literature regarding the assessment of the smart integration of PV/Wind Hybrid Power systems with Egyptian Electrical Network. and in Chapter 2 discussion Sizing and Optimization of PV/Wind Power System: Case study Supplying Large Industry Load in Egypt where the possibility of using a stand-alone hybrid PV/wind power system for electricity generation for large industry load, cement factory, in Egypt is investigated. To increase continuity of supply electrical power to load demand, a backup connection with grid Utility based on smart connection has been used. An economic feasibility study has been made for hybrid PV/wind system to power this large industry load. A case study was done at Assiut Cement Factory in Assiut City as a representative example of large industry load in Egypt. Sizing and optimization of the hybrid system components were investigated using MATLAB code and Hybrid Optimization Model for Electric Renewable (HOMER) software. The energy cost values of the hybrid system agree reasonably with those published before. And present in: Particle Swarm Optimization Technique for Shunt Chapter 3Active Power Filter, this chapter is aimed to design and study the performance of shunt active power filter based on Particle Swarm Optimization Technique (PSO) which is used to find out the optimal gains of PI controllers. PSO technique is designed to control the position and velocity of updating particles till reaches the optimum set. Modified synchronous reference frame theory is implemented to excerpt the reference current waveform. Intensive simulations are conducted based on Matlab/Simulation Tool. Design of shunt active power filter is agree with the proposed results. Optimal control circuit is quite superior as it is more effective even with the presence of non-linear loads and has a reasonably better dynamic response. Finally, Chapter 4: Modelling for improving power quality of Smart Microgrid/Utility Connection. In this chapter discussion the Integration of microgrids which connected to utility is considered as one of the most recently technologies to develop in countries like Egypt. The weather varying condition, power electronics and load demand in the low voltage distribution networks are the main issue problem in microgrid/Utility connection systems. This paper aims to provide a possible solution to some common and dangerous power quality issues and voltage sags, considering a large penetration of distributed generators. A deep energy and power analysis. A Matlab/Simulink developed to model and analysis of microgrid/Utility connection system for study the power quality issue such as total harmonic distortion (THD), voltage fluctuation at different loads.
With the rapid advances of recent digital signal and image processing technologies, it has become possible to perform tampering of digital images, easily. This breakthrough in tampering and intrusion process required new and efficient algorithms for image tampering and forgery detection. This thesis is concerned with the study of image forgery detection. Two models are presented in this thesis for image forgery detection.
