A Student Friendly Toolbox for Power System Analysis Using MATLAB

In book: Matlab - Modelling, Programming and Simulations
Source: InTech


Programs developed in this software package cover all the topics of basic power system analysis course. Examples from various widely available textbooks (Bergen & Vittal, 1999; Elgerd, 1983; Glover, 2007; Grainger & Stevenson, 1994; Saadat, 2009; Stevenson, 1982; Wood & Wollenberg, 1996) are taken as examples. These textbooks are used all over the world. So, students running the software find a familiar environment around. Apart from this, other examples can be tested using this toolbox since the programs are written in a generalised

    • "Load flow analysis is used to carry out this study on the power system network. [1] To obtain the complete description of the power system, therefore, it is necessary to know the voltage at node points or buses and the power flowing through the elements of the system. Due to the growing demand of power and the unbundling of the network, the power system network has become very complex. "

    ABSTRACT: Slack bus is a bus with generating unit and used to balance the real power (P) and reactive power (Q) in the power system while performing load flow studies. This study therefore, investigated the best slack bus suitable to be used in the load flow study of the Nigerian 330-kVtransmission network with nine (9) generating stations. The method involve the load flow analysis of the existing network with Egbin, Shiroro and Kanji generating stations chosen as a slack bus at different instances and simulated using Newton-Rapson method and Gauss Seidel. This study revealed that the use of Egbin power station as a slack bus brought about the lowest power mismatch in the network. The result also indicated violation of voltages in some of the network and high reactive power loss.

    ABSTRACT: In this paper, a new methodology for stability assessment of a smart power system is proposed. The key to this assessment is an index called betweenness index which is based on ideas from complex network theory. The proposed betweenness index is an improvement of previous works since it considers the actual real power flow through the transmission lines along the network. Furthermore, this work initiates a new area for complex system research to assess the stability of the power system.
