PSAT Power system analysis toolbox is an open source toolbox which is compatible with MATLAB that makes possible in re-using existing code and merging different software packages into new and less costly applications. This panel paper presents the study of IEEE-6 bus system for steady state analysis with different load level flow methods such as Newton-Raphson, Fast-Decoupled method.
They are necessary for planning, operation, economic scheduling and exchange of power between utilities. The principle information of power flow analysis is to find the magnitude and phase angle of voltage at each bus and the real and reactive power flowing in each transmission lines. Power flow analysis is an important tool involving numerical analysis applied to a power system [1]. Symmetrical steady state is, in fact the most important mode of operation of a power system.
Load flow study in power system parlance is the steady state solution of the power system network. The main information obtained from this study comprises the magnitudes and phase angles of load bus voltages, real and reactive power flow on transmission lines, other variables being specified.
This information is essential for the continuous monitoring of the current state of the system and for analyzing the effectiveness of alternative plans for future system expansion to meet the increased load demand. In the absence of digital computers, the AC calculating board was the only means of carrying out load flow studies. These studies were, therefore, tedious and time consuming [2].
With the availability of fast and large size digital computers, all kinds of power system studies, including load flow, can now be carried out conveniently. Now days there are many software packages are available to perform the load flow analysis. Commercial software packages available on the market e. For research purposes, the flexibility and the ability of easy prototyping are often more crucial aspects than computational efficiency.
On the other hand, there is a variety of open source research tools, which are typically aimed to a specific aspect of power system analysis. There are several high level languages such as Matlab, Mathematica, and Modelica, have become more and more popular for both research and educational purposes. Any of these languages can lead to good results in the field of power system analysis; however, Matlab proved to be the best user choice.
Key features of Matlab are the matrix-oriented programming, excellent plotting capabilities and a graphical environment Simulink which highly simplifies control scheme design. This paper describes a new Matlab-based power system analysis tool PSAT which is freely distributed on line [3]. PSAT includes power flow, continuation power flow, optimal power flow, small-signal stability analysis, and time-domain simulation. The toolbox is also provided with a complete graphical interface and a Simulink- based one-line network editor.
To allow exchanging ideas and effectively improving scientific research, both the toolbox and the platform on which the toolbox runs should be free.
