  • DG Placements Impact on the Reliability of Typical Industrial Distribution
           System In Saudi Arabia

    • Abstract: DG Placements Impact on the Reliability of Typical Industrial Distribution System In Saudi Arabia
      Pages 91-95
      Author M. H. ShwehdiDr. Suliaman ForteahS. Raja Mohamma
      Electrical Distribution systems that are usually radially configured with one utility power source are inherently exposed to higher rates of outages and interruptions due to the fact that failures of system components including transformers, breakers and switching devices along with fault conditions caused by different conditions are not preventable but rather improvable. Historically at Saudi Arabia (SA), many industrial and residential distribution networks suffered from the problems incurred by the utility grid connection including equipment failure, low power quality or human, animal and weather conditions. The fact that the large-size, the growing demand and the cost with the time requirements for enhancements projects have made distributed generation (DG) in all its application, namely, online or backup to play a key role in the residential, commercial and industrial sectors of the power system. In this paper, the value of DG installed as an online power source of typical industrial distribution network at SA (Abqaiq) is quantified by reliability indices that include SAIDI, CAIDI and ENS. The study outcomes will provide power system engineers with the sense of the reliability benefits of DGs penetration and an approach to assess its installations based on different factors such as the size and location.

  • Novel Selection Approach of STATCOM Device Tailored and Optimized
           Engineering Configuration to Implement in Between Qatar and Bahrain

      This paper presents a nontraditional control and operation of a STATCOM connecting the Qatar and Bahrain in the Gulf Cooperative Council Interconnection. The proposed work will demonstrate precisely STATCOM control parameters, improving the STATCOM performance at different transmission contingencies. The integrity of the proposed control system topology is evaluated through set of time based simulations by using Matlab. Based on simulation results which clearly show an increase of the loadability, reduction of the losses and enhancement of the sustainability of the GCC Interconnection can be achieved.

  • The Effect of Adding a Large Load and Study Stability of Grid with
           Distributed Generated Power

    • Abstract: The Effect of Adding a Large Load and Study Stability of Grid with Distributed Generated Power
      Pages 85-90
      Author Aliakbar AzariS. Abolfazl FakoorianM. Amin NoferestiM. reza Aalam
      In this paper, it has been examined how distributed generation makes effect on grids. The answer to this question can be that there are losses at all levels in the power system like generation, transmission and distribution, however, 75 percent of which occur in distribution grids. Reason for this is the high amount of current lines, due to the low voltage in distribution grids and radial structure of these grids. In this paper adding a large load on the bus located in the farthest part of grids has been investigated and consequently by adding instant and unexpected load to the specified sheen, instability is created in the grid. Grid was analyzed in terms of load voltage and line losses. Simply when a load is connected to Shane unbalanced voltage arising on the desired bus and we must compensate this imbalance in specific way which is elucidated in the following paragraphs.Simply when a load is connected to Shane arise unbalanced voltage on the desired bus and we must to compensate be some way this imbalance.
