Abstract: The drastic increase of residential load consumption in recent years result in over loading feeder lines and transformers for the Iraqi northern area distribution system especially in the city of Mosul. Solution for this problem require up to date research study consumers load to find the proper solution to stop excess overload in the transformers and the feeders. This paper include the regional survey for samples of consumers representing typical types of different standard of living and energy consumption by distributing questioners contain list of information such as load type in daily use. Also current readings are recorded for the individual consumer for the months of the year 2006. In addition to those readings, energy consumption is recorded once every two months. The registered readings are used in conjunction with the list of questioners to find a sample (for different loads) that coincide with the list of questioner for current and energy readings. Resulting in the feasibility of using the sample to know the peak value of current for any consumer not included in the list of questioner and for any new consumer, since it become possible to decide the size of the transformers and feeder lines, to overcome the problem of overloading in any part of the distribution system. The Artificial Neural Network (ANN) is used in this paper to find the above mentioned sample.

Abstract: Static synchronous compensation (STATCOM) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, STATCOMs are employed for reactive power support only. However, with the integration of energy storage (ES) into a STATCOM, it can provide active power support in addition to the reactive power support. The control method of a STATCOM with an energy storage device is discussed in this paper. To determine the switching level control, SPWM (Sinusoidal Pulse Width Modulation) methods is used. This paper will introduce an integrated STATCOM/BESS for the improvement of dynamic and transient stability and transmission capability. This work suggests a simple and easy to implement PI controller to control the operation of ESTATCOM placed at the weak point of Mosul city 132 kV ring system. The whole system including the ESTATCOM and its controller has been simulated after some kinds of disturbances and the results show improvements in the dynamic active and reactive power capabilities of the system.
