Abstract: Solar energy systems based on photovoltaic (PV) cells have attracted considerable interest in recent years due to their abilities of clear and seemingly limitless generated energy. Solar energy systems based on microinverter architectures are earning in publicity as they are less prone to shading and PV cell malfunction since each PV panel in the system has its own low power inverter.In this thesis two alternative modes of operation for the current source flyback microinverter are suggested : the discontinuous conduction mode (DCM), where a constant switching frequency (CSF) control method is applied, and the boundary conduction mode (BCM) between continuous conduction mode (CCM) and DCM, where a variable switching frequency (VSF) control method is used. These two control methods are analytically studied and compared in order to establish their advantages as well as their suitability for the development of an inverter for grid - connected PV applications.An optimum design methodology is developed, aiming for an inverter with the smallest possible volume for the maximum power transfer to the public grid and wide PV energy exploitation. The main advantages of the current source flyback microinverter are very high power density and high efficiency due to its simple structure, as well as high power factorregulation. The design and control methodology are validated by Powersimulation software (PSIM) and a laboratory hardware prototype is buildusing analogue and digital devices.The microcontroller type (PIC - 18F45K22) is used to implement perturb and observe (P&O) maximum power point tracking (MPPT) algorithm, and C language is used for programing the microcontroller. The simulation and experimental results are obtained to verify the proposed flyback microinverter.

Abstract: اصبحت محركات التيار المستمر عديمة الفرش شائعة جدا في الكثير من المجالات مثل في الصناعة والتطبيقات المنزلية؛ وذلك يعود الى مميزاتها العديدة على محركات التيار المستمر ذوات الفرش والمحركات الحثية؛ مثل كفائتها العالية, كثافة قدرتها العالية وحجمها الصغيرنسب | Brushless DC (BLDC) motors have become very popular in various fields such as in industry or home appliances; and that is due to their many advantages over the brushed DC motors and the induction motors such as their higher efficiency, high power density and respectively low volume. The traditional and most popular way to drive BLDC motor is by using six - step or trapezoidal technique. This technique however has several problems such as high torque ripple and high distortion in the currents. This thesis presents a BLDC motor drive system where the performance of the motor is improved on various aspects. The first aspect is to improve the speed response by using particle swarm optimization (PSO) technique to find the optimal parameters of the speed controller. The second aspect is to reduce the torque ripple associated with the traditional driving technique and also improve the dynamic response of the motor by using vector or field - oriented control to drive the motor. The third aspect is improving the total harmonic distortion (THD) of the voltages and currents by using multilevel inverter. The last aspect is driving the motor in sensorless operation for reduced cost and for applications where speed and position sensors cannot be used; this operation uses a flux - linkage observer with a phase - locked loop (PLL) structure to estimate the position and speed of the rotor. The control methods are modeled using MATLAB/Simulink program and the results show that the proposed systems has significant improvement in performance as compared with the traditional technique in terms of speed response, torque ripple and THD of the voltages and currents

To this end, the generator unit is equipped with an automatic load frequency control (LFC) to adjust the active power produced and restore the frequency and tie line power exchange to their nominal value.The total model of a hybrid power system has a high dimension. The classical design tools are inadequate to cope with all dynamic features. Artificial intelligence techniques are found to be a promising tool to optimally minimize the transient dynamics and control efforts in a load frequency control. This thesis shows the execution of various Artificial Intelligence techniques on the tuning of PID controller in a load frequency control system to compute the PID controller. The techniques of genetic algorithm technique GA, particle swarm optimization PSO and artificial bee colony ABC were applied on four areas, six tie lines power system. The dynamic model was formulated in state variables form. A comparison between these techniques with different performance indices was presented. Results of the test system 1 and 2 were computed and compared. They showed that in test system 2 the load frequency controller can chase the load fluctuation in a short time. The IAE performance index gives an optimum dynamic performance using ABC. From the outcomes, they show that the test system 2 outputs regarding settling time and maximum overshoot were the best performances.

The charger is the most important part of the solar system because the only limited - age part of this system is the storage batteries. Storage batteries are essential in all standalone PV power systems. Their efficiency and life time affects significantly the overall PV system performance and economics. The storage battery's effectiveness depends on the charging process. Hence, this thesis deals with the study, simulation and design of an intelligent charger fed by solar system due to the latest technologies.The developed charging method entitled "the decreased charging current based on state of charge" is adopted in this thesis to charge a lead - acid battery. The principle of decreased charging current is to make the real charging current as close as possible to the maximum acceptable current.

Abstract: The Wind Energy is one of renewable energy and has become very popular and more attractive, as a result of many factors, some of these factors are, rising oil prices, worldwide awareness of the decline in world oil production, an raise in the price of natural gas. Therefore the need for renewable energy has been very important.This work deals with Doubly Fed Induction Generator (DFIG) based wind turbine. By studying the performance of DFIG connected to the grid with constant and variable speed wind. Three cases are considered and implemented using Matlab/Simulink. The first case is studied the effect of the size of capacitance at DC - bus with constant wind speed using space vector pulse width modulation (SVPWM) switching frequency 10KHZ and two values of capacitance.The second case is studied the effect of three phase fault condition, at 33KV line.The third case is that when the input is variable speed wind, the simulation results illustrate that is with variable wind speed and conventional values of PI controllers gains the generator system behavior show increasing in rising time and maximum overshoot of generated power, the control circuit is needed for optimization to improve the generated power. This optimization can be made by tuning the controllers parameters with optimal values, so the optimization is made by using Particle Swarm Optimization (PSO). The new optimal controllers parameters(PI - PSO) make the system more efficient from the results by reducing the ripple of DC - Voltage and maximum overshoot.

Abstract: يعتبر تخمين حالة منظومات القدرة الكهربائية من الامور المهمة في تشغيل منظومات القدرة وخصوصا في حالة الحمل الزائد على شبكة الطاقة الكهربائية من خلال دوره في ضمان تشغيل اكثر اقتصاديا وامانا. تم في هذا العمل دراسة تخمين حالة منظومة القدرة واقتراح طريقة فعا | Due to the increasing stress on power system networks, state estimation recently became a main matter in the operation of power systems through its important role in ensuring the secure and economical operation of the power system. This work presents a study of a problem of power system state estimation, and proposes an efficient and reliable optimization approach to solve the power system state estimation problem. Two programs have been proposed and implemented in order to overcome the disadvantage of the classical optimization problem and search for the optimal solution of state estimation in power systems, the first program is a conventional state estimation program based on Weighted Least Square (WLS) method, and the second program is an intelligent program based on Particle Swarm Optimization (PSO) technique. All programs have been implemented using MATLAB and have been developed to solve the state estimation problem of the Iraqi Super Grid network (400kV). The proposed programs have been examined and tested on the 14 - bus IEEE and 30 - bus IEEE test standard system. The results were compared with those of the previous published papers. Then, the two programs were applied on the Iraqi Super Grid network (400 kV). The tests proved that the two methods are very efficient and suitable for on - line applications since they are concise and require few computations. The results show that the convergence of the (PSO) technique to the optimal solution is more accurate than (WLS) method. On the other hand, the PSO has an acceptable execution time compared with the freezing time of Iraqi Supervisory Control and Data Acquisition (SCADA) system approved by the Iraqi national grid.

Abstract: يعد تخطيط شبكات التوزيع الكهربائية من الاولويات في الوقت الحاضر في العراق نظرا للزيادة الهائلة في الاحمال الكهربائية والتوسعات المفروضة على الشبكات نتيجة التوسع العمراني الكبير والسريع.يتحقق الاداء الامثل للشبكة بتقليل المفاقيد‘ تحسين الجهد (Voltage pr | Planning of electrical distribution networks is considered of highest priority at the present time in Iraq, due to the huge increase in electrical power demand and expansions imposed on distribution networks as a result of the great and rapid urban development. Optimum performance of the electrical network is achieved by reducing losses, improving voltage profile and alleviating overload for the system components. Such operation provides for energy salvage and redundancy in the electrical network. A planning method is proposed in this work to achieve optimum operating conditions of the network by combining the network reconfiguration in conjunction with the insertion of capacitors of optimal sizing and locations. This method is classified as a huge discrete non - linear optimization problem due to the large number of variables along with the presence of constraints and objectives. The power losses and voltages in buses for all cases are obtained by backward/forward load flow method. The proposed planning of distribution networks is based on the powerful and advanced CYMDist software as a tool for the simulation of distribution networks and performing the required analysis. CYMDist is practical and efficient analysis software, which is used by many electrical companies worldwide as well as the Iraqi ministry of electricity.Optimal network reconfiguration and capacitor placement methods are tested on IEEE 33 - bus and IEEE 34 - bus test systems, respectively. The results show excellent matching as compared with previous work mentioned in the literature.The work is implemented on an actual sector from Baghdad city distribution network, which is Al_Bayaa 11kV, 145 bus, four feeders system. The presented results show that minimum active power losses with improved voltage profile had been achieved. So the network can operate normally without any constraints violation.

In this work, the effect of different types of disturbances on the performance of fixed speed of wind turbine generator type Squirrel Cage Induction Generator (SCIG) connected to the power system has been investigated, because it has features which make the best choice in some cases, despite the less efficiency compared with other types of generators. Also, this work aims to study and analysis the effect of (STATCOM) on the wind turbine generators because of its advantages in improving voltage stability of the grid and improving the quality of the productive power. The proposed work is performed using MATLAB/Simulink. The intelligent systems have been used to obtain the best performance in terms of extracting more power from wind energy as well as increase the stability of system in situations of disturbances and the results obtained have been compared with conventional control systems.Three types of controllers are proposed in this work; the first controller is the Proportional - Integral (PI) based on classical trial and error method, the second controller is PI - controller based on Particle Swarm Optimization (PSO) technique for optimal tuning (gain) to improve the performance of the system. The results obtained proved that the PI - controller based on Particle Swarm Optimization (PSO) technique is better than based on trial and error method. The third controller is (Nonlinear Auto regressive - Moving Average) NARMA - L2 based on (PSO). Finally, the results of the proposed controllers show that NARMA - L2 controller is more effective on the stabilization and improves the performance of the system compared with PI - PSO controller

Abstract: With limited enhancement or expansion of the transmission infrastructure, the contemporary power systems are operating under more stressed conditions. It becomes important to fully utilize the existing transmission system to supply load demand as much as possible, thus eliminating or reducing the need for new transmission investment. Flexible AC Transmission System (FACTS) technology provides a method to fully utilize the existing transmission lines as well as new and upgraded lines. However, the implementation of FACTS devices in the transmission system has introduced new power system dynamics that must be addressed in the area of power system protection, such as rapid changes in line impedance, line current and voltage. This thesis reports the results of comprehensive study carried out to explore the impact of mainly two of the FACTS devices, Static Synchronous Compensator 'STATCOM' and Unified Power Flow Controller 'UPFC', on the distance protection relaying system in order to identify important issues that protection engineers need to consider, that is during the stages of design and operation of the protection system. Simulation studies are carried out using MATLAB/SIMULINK. First, the distance relay has been modeled and validated with FACTS device models using test systems from literature. Then the distance relay performance is analyzed and evaluated for various fault and loading conditions in the presence of FACTS devices. A comprehensive study and results for one of the Iraqi 400kV transmission lines (KDS4 - NSRP transmission line) are presented and useful recommendations can be presented to the General Directorate of electrical Power Transmission for Middle Euphrates region / Iraqi Ministry of Electricity. II Abstract Generally, the results show that the apparent impedance seen by the distance relay would be different from that of the system without FACTS devices. Due to this, the distance relay may malfunction, resulting in undependable operation of the power system protection during faults. Furthermore, the results show clearly the dependency of the distance relay operation on many design and operational factors. These include the FACTS device type and its use purpose, the FACTS device connection point or location, the fault type and fault point location along the line, the power flow,...etc.

The thermal limit of transmission lines and transformers was studied in cases , with DG and without DG, to detect the lines or transformers which exceed the limit in order to processed it. The voltage stability of distribution network has been investigated, using L index (which aims to detect the vulnerable load buses of an electrical power system). Also the rotor angle transient stability of DG units has been calculated to specify the critical clearing time (CCT) of each circuit breaker in distribution network when one of transmission lines is exposed to three phase to ground fault. The developed algorithm has been verified using two test systems IEEE 33 - bus distribution system and the WSCC 9 - bus test system, furthermore applied to a part of Iraqi distribution network (Al - Najaf Al - Ashraf distribution network). Two softwares are used in this work , the first is Matlab R2013a for implementation of the PSO and voltage stability algorithms while the second software is Power World Simulator 15 for implementation of the thermal limit of transmission lines and transformers, and rotor angle transient stability of DG units.DG contributed significantly to reduce the power losses in Al - Najaf Al - Ashraf distribution network, where there is a reduction by about 96% in active losses. Also DG processed the overload of large substations and the stability of buses in the network.
