The electrical power transmission system serves as the vital artery that supplies energy consumption centers, as it represents the link between production and distribution stations. This system consists of a set of stations and lines with varying electrical loads in Basra Province. High loads are concentrated in its eastern side due to the high population momentum compared to the mostly uninhabited western side, which consists of desert regions. The transmission process faces a range of problems, including load instability from energy supply sources, high line losses, as well as congestion in some stations and lines. To improve energy transmission efficiency, it is necessary to rehabilitate and update the lines and stations by developing and upgrading their physical components, or by utilizing solar and wind energy as ideal solutions to the energy system's problems. It has been shown that the use of these energy sources reduces the burden on transmission networks by 18.3%, 43.4%, 23.64% for the spring, summer, autumn, and winter seasons, respectively.

The renewable energy is regarded as one of the basic necessities in which many countries have relied to move the wheel of development forward, The rate of energy consumption was considered as an indicator of nations and peoples progress as electric energy represents the infrastructure of various contemporary activities that many countries adopt in their economic growth. The programs of energy development is not taken into account unless there are developing plans not concerned with change, progress and not to deplete fossil fuel resources, which has been depleting in recent times because of the increase in demand for electricity and for the high in oil prices, research concerned the possibility of finding a new resource of electric energy, The solar and wind energy in an important step to solve the problem of electric power crisis in Mosul city and the beginning of energy self-sufficiency . The research aims to identify the concept of developing the renewable energy industry and its types, in addition to know the impact of the natural geographical features in Mosul city to clarify its role in developing the renewable energy industry to know the appropriate sites to establish sites for solar cells and wind farms and their establishment in the study area, for the problem of power outages was regarded as one of the basic problems facing the Iraqi state, including Mosul city, this asked us to study this problem through renewable energy to reach methods to solve it. The study showed that there are three levels of spatial suitability to choose solar cell sites which are inappropriate areas and occupies 2.8km 2by 4. %1of the area of Mosul city. It included the areas that are in the shadows of the hills facing the solar radiation, whose slopes are towards the north, and suitable areas of medium degree which occupies 115.9km2, %2.58which includes most of the city’s area that's increased in the east and west of the city for relatively high which occupies 80.3km 2by%3.40. It includes most of the city’s area and increases in the east and west of the city, being high areas and their slope towards the south that receive large amounts of solar radiation.

After studying the reality of electric power service, which is the backbone of the development of cities and their civilized, technological and economic progress after their recent entry into the various fields of life. By reviewing the service reality of this sector in the study area, the results showed that there is a significant lack of infrastructure in electrical power services from major and secondary stations with voltage 11/33/132/400 K.V. as a result of the significant destruction of its infrastructure. Which was the reason why the study area was unable to benefit from the energy generated from the Mosul dam station, which made there a significant shortage of this service towards the population and covered the annual increase of energy required for the study area.

In this paper two power elements for power controller in transmission line are presented: Variable Frequency Transformer (VFT) and Rotary Power Flow Controller (RPFC). In addition, here a new Optimal Power Flow (OPF) with these elements is presented. In this paper, it has been made use of the Impedance and Admittance nonsymmetrical matrix and the matrix of loss or coefficient B are calculated in a new method. It has also been indicated that the system is not optimized if optimal power flow is not considered in locating and power of flow controller in line. The proposed method was applied to a 26-bus and 6-generator system and the results were satisfactory. [ABSTRACT FROM AUTHOR]

This paper presents a study about of a fuzzy Controlled STATCOM, which can be applied for mitigation of the voltage flicker in a distribution system. The voltage flicker is produced by a large variable load absorbing continuously changing currents such as an arc furnace. The DSTATCOM includes a voltage-sourced PWM inverter and its control system. The control strategy of the DSTATCOM plays an important role in maintaining the voltage flicker. Here, the DSTATCOM controller is designed with two types of controllers, linear proportional-integral (PI) and nonlinear fuzzy logic. The simulation of the DSTATCOM with 3MVar reactive power on a 25 KV distribution network is carried out in MATLAB/SIMULINK software. At the end of the paper, fuzzy controllers were evaluated by comparing its performance with the PI controllers. It is observed that the fuzzy controllers are very superior in mitigating the voltage flicker. [ABSTRACT FROM AUTHOR]
